1985-86 RoV
newsletters
Already in 1985, long before
Internet made it all easy, a group of USA/Canada XZ550 or Vision riders started
to communicate and had an RoV-newsletter.
As this early enthusiasm is
now more than 20 years old, it is worth to record.
NightVision of the ROV-forum has some early newsletters. He
scanned the numbers 1, 2, 3 and 6 and mailed these to me. The first issue
already discusses stators and starter clutches! In number two is a discussion
on the (in)famous Vision stumble (they called it Vision lag in those days).
I expressly want to thank don_vanecek (who preserved these old issues and sent them to NightVision) and of course NightVision
who send me this and other information and who suggested to me to make this
information available to anyone who is interested.
I will proceed
as follows: the first ROV Newsletter, of November 1985 has 6 pages. I will
publish the first issue completely. Later issues I will read for interesting
information and I will publish the information I consider as interesting.
Anyone wanting the complete content of the issues 2, 3 and 6 can ask me (XZv2@hotmail.com) or NightVision.
At present, at
the end of May 2006, the # 1, 2, 3 and 6 Newsletters are ready. If there are
any more numbers around somewhere, it would be great to have the complete set
here available for anybody interested.

Vol. 1 No. 1 Riders of VISION Newsletter November 1985
Welcome to the first issue
of Riders of VISION Newsletter.
It started when Torn McKaskle wrote the following letter which appeared in Cycle
Magazine.
"I was pleased to read
your comments on the Yamaha VISION in the April issue. I certainly enjoy mine.
The looks may not appeal to some, but at least it doesn' t try to look like
something it isn't (i.e. a Harley). Form follows function. 1 would like to
hear from other owners who are interested in starting an owner's club."
Tom (now Rider of VISION#1)
received many letters expressing an interest in forming a club. Unfortunately,
Tom was not able to continue in his efforts to form a club due to unforeseen
circumstances. He asked me to fellow through.
My name is Paul Robinette
(RoV#028) and am very enthusiastic about a VISION
club. At the present time I have no idea where this is going to take us. I say
"us" because a club of any kind is never made up of an individual.
You are the club.
What we do now is up to all
of you who receive this first newsletter.
At first I was stumped about
what to do or write. Tom sent me your letters and it was your letters that gave
free the insight on how to proceed with this VISIONary
endeavor.
What to do was to start off
with a newsletter, according to your letters.
The best news to write for a
newsletter is your letters!
It is your letters of
enthusiasm, ideas and questions that we will share with our fellow Riders at
VISION.
From Tacoma, Wash.
Brian DeFrees (RoV#019) wrote Tom, “I read of your
interest in beginning a club. I just purchased a new '83 VISION in April after,
having relished ownership of one for years. I am pleased to respond to your
invitation. Boy, 1 surely do love this bike”. That
says a lot because I've owned a Suzuki GS1000 shaft, '82 Goldwing
and an '83 Nighthawk among others.
I sincerely hope you become
deluged witte responses for
the club -- nationwide.”
The responses have been more
than nationwide. Toms' letter has generated interest among our brother Riders
of VISION north of the border! Paul Moore (RoV#014) wrote from Newmarket, Ontario, Canada,
"Please count me in if you want to form a VISION owner's club. My VISION bas given me hours of enjoyment during the last three
seasons and with a little luck, many more. Yamaha built a great bike in
the VISION and it is a shame more people don't know about it. Please write me
as soon as possible. I am willing to help organize the club on this side of the
border.”
Ok Paul, this is it! What we
need is more enthusiasts like you to join us!
Everyone receiving this
newsletter is a member of the club. You owe no dues and your membership number
was determined by the date that Tom received your letters. Your RoV# is marked on the mailing label used to send this to
you.
The only requirement at this
time is participation. You all showed an interest and willingness to make a
VISION club work. By taking the time to write again you will obligate me to at
least publish one more RoV Newsletter. What you write
in response to this newsletter will determine our future course.
One of our Naval members is Bruce Rodgers (RoV#021) of the U.S.S. Guadalcanal. He
offers some guidelines for forming the club. "First establish how big you
want to go. As small as the Yamaha 'T' Register or as big as
the AMA (the American Motorcyclist Association). We need to find out
how many registered owners Yamaha has.
Second, find out what the
potential members would like to sec offered from the club. Maybe a questionaire would be appropriate.
Third, establish a baseline
for dues ....”
Bruce also discussed
patches, t-shirts and affiliation with the AMA.
Everything is open for
discussion at this point except dues.
Why? Because I feel
responsible for this organization that Tom has entrusted to me. I do not want
to mislead anybody about the future of Riders of VISION. Clubs come and go and
only time will tell if WE make this club work. So no dues.
Contributions will be accepted to defray the cost of postage and miscellaneous
expenses. If you wish to contribute money, just address it to me at the return
address on the envelope that you receive this newsletter in. You will receive
credit against any future dues that the Club decides upon (the Club wilt decide
that -- not me!).
For the future record 1
nominate Tom as President of the Riders of VISION Motorcycle Club. Do I hear a
Second?
Bruce also volunteered in
the military tradition to submit technical articles about the VISION based upon
his expertise gained at various mechanical and motorcycle schools. We'll all be
looking forward to your articles Bruce'! Thank you.
David Kimmey
(RoV#013), of North Miami Beach, Fla. writes that he is involved with County
Wheels News, a local motorcycle monthly newspaper. He writes, "I would
like to see a sort of semi-monthly newsletter published which would hopefully
provide VISION owners with much needed tips and information. Individuals who
are experiencing problems in certain areas could write to the central address
for information."
Dave also suggested letters
to motorcycle magazines to announce a VISION club and possibly paid
advertising in the magazines.
I like his ideas and look
forward to see how the rest of you feel about them. (Well, except for
semi-monthly maybe ... unless I get some help. Say Dave, you're a journalist
….) Seriously though, I am willing to go as far with this as possible. We would
need somebody more mechanical than I am though to act as an "Information Center". With enough contributions (letters, letters, letters!) our
newsletter should prove invaluable for VISION owners.
From Olrleans,
Ont., F.L. Baldwin says he is owner #675 of VISION and that he is also
interested in organizing VISION owners.
He writes, "I intend to
proceed by contacting the main magazines, identifying an organization is being
developed and request owners contact me with a few relevant facts such as 1)
name and address, 2) year and serial number, 3) where purchased, 4) likes and
dislikes, 5)
other bikes owned, 6) history of problems, 7) type of riding/usage, 8)
options/accessories and 9) misc. info."
R.L. feels the information
he hopes to compile will be useful for all VISION riders and is the minimum
needed for a VISION organization. Baldwin asks
if anyone is interested in helping and offers to put anyone into the listings.
I am unclear at this time if
the writer plans to go it alone or wants to be considered a Rider of VISION
number Three. Until we hear otherwise we will consider our Canadian friend
RoV#3 and I for one will send the information about my bike up North. Address
any letters to: R.L. Baldwin, 6029 Vineyard Drive, Orleans,
Ontario, Canada KIC 2T7
Dr. Luther Leake, (RoV#023) of Arden
Hills, Minn. asserts,
"VISION owners seem to be an ideal group to organize since the bike had
such a short production life, appealed to those 'special few' and is just such
a great motorcycle. Also I think VISION owners need a voice in dealing with
potential part-, and accessory problems.
Did you get the VISION belt
buckle mailing list from Yamaha? I bet
they would give a club a good deal on them, and they could be offered with club
membership."
No, we don'
t have the VISION belt buckle mailing list from Yarnaha.
Yes, they would be a great offer for the membership. I hereby appoint myself to
check further into this idea and wilt let all of you know the results by the
next newsletter. I do need to know how the general membership feels about the
club getting involved in offering merchandise to its members and prospective
members. (Again -- letters, letters, letters!)
From a little further south
by east Jim Gentry (RoV#022), of Walterboro, S.C. writes about his experiences riding a VISION at the
AMA convention held in the mountains of Virginia.
"The above mentioned
convention was great! I mean I had a fine time. My wife had to tag along and
she does'nt ride. She has sort of like a phobia where
she says she can just feel pavement sliding across skin.
Out of all the motorcycles:
there (Viginia ‘85) I saw only one VISION. It was
ridden by a Motorcycle Safety Training Instructor with whom I talked.
Said he had been riding his
VISION ever since he got it in '82. Also said he had seen your letter in the
magazine.
Of interest: he solved the
mushy front brake problem with a braided
metal (brake) hose.
The main purpose of this
letter is to say that if you think we should have a club I' me for it"
It would be fun to see more
VISIONS at a run. As Jim, found out it can also be educational. (We ‘ll hear from Jim again.)
Carl Mailander
(RoV#007) of Webster City, Iowa wrote on the subject, "I am writing in
response to your letter that appeared in Cycle magazine. I love my VISION too
and would be interested in hearing front you if you can get an owners club
started. I think it would be a lot of fun to have a VISION Bike-In sometime if
enough people are interested.”
Front Carmel, Calif. James Perkins (RoV#030) said,
"Let me know as soon as you have a VISION Ride-In organized. The Monterey Bay Peninsula
would be perfect for a ride-in with all the tourist attractions and sights
here.”
A ride-in certainly would be
fun. 1 for one would love to see what Riders of VISION have done with their
machines and exchange ideas with them. This is the time of year to plan such
an idea .. but it may be a
bit premature at this time. Let me know (letters, letters, letters!).
Going on long rides seems a
natural for VISION riders. Bernice Miles (RoV#006), of The Dalles,
Ore. Writes: “I've owned a 1983 VISION since March 1994 (got it “new"} and
so far I’ve got 17,000 miles on it with no troubles. My husband and I took a
6,000 mile trip last sommer across Canada to Lake
Superior, Iowa, Kansas, Colorado end Arizona. The only trouble I had with the
VISION was a big knot on the front tire that 1 noticed in Page, Ariz. at the end of the
day. The tire had 24,000 miles on it then.
There was a motorcycle shop
in Page that had only started up six months before our arrival that took care
of the tire while my husband and I had breakfast."
Outstanding! My only
question Bernice is what did your husband ride on your tour? 1 hope it was a VISION! Please write again about your tour
(and other VISION experiences too!). Another VISIONary
tourer is Frank Moore (RoV#017) of Austin, Texas.
Frank has rode his VISION over 25,000 miles in sixteen
months! His travels have taken him from Key
West, Fla. to the
high Sierras of Chihuahua.
“Returning from Key West and the Everglades I was on the east side of Lake Okechobee when the right
front exhaust pipe came loose from
the engine. Loud! ! ! A fifteen year old boy at a
garage replaced the two metric bolts in ten minute for five dollars.
Then in the rural boondocks
of eastern Mexico
the rear battery connecting bolt came loose.
I couldn't see the problem
because the rubber boot hides that terminal. Again a fifteen year old boy came
to the rescue. The young local rode by on a bicycle, and soon jump-started the
VISION with a truck battery and two pieces of baling wire!
In Mexico the common people were
overwhelmed by my Yamaha. One KZ750 owner noticed my YPDS belt buckle matched
the bike! They all asked the price of the bike and 1 modestly gave them the
lowest retail quote. Because the displacement isn’t stated on the side, even
bikers assumed it was at least a 750.
I think VISIONs
have the potential for being a “cult" bike, so let's start organizing the
right kind of cult!”
He went on to say that he
was headed to Manitoba
for August and to let him know what was happening with the club. Sorry Frank,
by now you’re back and really wondering -- please blame it on your editor,
accept my apologies and write us about your Canadian adventures! (right -- letters, letters, letters!)
Frank also wrote about his
mechanical experienes with his VISION.
"Luggage racks: YPDS
makes the best VISION rack. It's custom, fitted close
to the seat over the rear wheel. Even a full tail trunk won'
t let the bike be unmanageable going down a mountain fast -- which I’ve done.
Saddlebags: the black bags
by Yamaha with white and red horizontal stripes are excellent. You leave two
webbing straps mounted on the passenger saddle.
The fastex
buckles on the straps and on the bags are easy to use. But you can't carry the
bags and a passenger. I put the bags in my puptent
when I get to the Campsite.
Tal trunk: small or medium trunks will fit on the
factory luggage rack (but not the larger trunks). 1 never got a top-rail for
my trunk because I believe the load could be top top-heavy.
Tankbags: even a 24 liter Bagman fits (but that much will
crowd you).
Tires: My '82 VISION has no clearance problems with
the Dunlop MP90H-16 Tour Elite or the Conti Supertwin
425/B5V-18 on the rear wheel. A Dunlop 110/90V-18 Sport Elite tire fits on the
front. Unless you should have bought a GPZ or Interceptor the tread compounds
of the above tires will give you plenty of cornering power. 1 thought the Tour
Elite handled better than the stock Dunlop.
Alternator: The early VISIONs (and Ventures) need to have their stators replaced.
I recommend having it checked out during the last month of warranty. The new
parts are improved.
Crash bars. Essential! If a
VISION falls on its right side the sharp edge of the brake pedal punches a hole
in the side case. Do not start the engine if anything falls inside the case. A
factory case only costs about sixty dollars."
Thanks Frank for your
information. Sharing ideas and experiences help make a club, according to Dick
Richardson (RoV#029) of Omaha,
Neb.
"I bought a new '82
VISION (gray) the other day and so far certainly enjoy it.
But, there are several
changes that can be made to the '82s in the suspension area. It would be nice
to know for instance, which changes do make a difference. Also, my bike has the
new carburetor kit in it but there is still a flat spot at the low end.
Possibly the carbs need a good cleaning?
Questions, answers end
experiences with fairings, suspension, rear dampeners, tires, gasoline and
touring and traveling help make a club!"
Right you are Dick. I hope
this newsletter will help answer some of your questions. (Yep.
Letters, letters, letters!).
Karl Retzlaff
(RoV#010) of Waukon, lowa also wrote about a lean
spot in the carburation of his ‘82 VISION. He says
that he hasn’t been able to find anyone that knows a fix for the problem. I am
sure that one of our Riders of VISION will accept this challenge.
As I promised earlier
(remember Virginia
’85) we'Il hear from Jim Gentry again. In his second letter he offers some
mechanical experience.
"Have you had any
trouble with the starter in cold (40 degree or less) weather? In case you
haven't I'm going to tell you about mine so that you will know.
I was cranking the engine
last winter and all of a sudden the starter began free wheeling so that I
thought the “bendix" (as in car starters) was
broken. I don't have a dealer within fifty miles so I took off the case cover
and made a rig to pull the flywheel. For my trouble I found there is nothing to
break in the VISION starter mechanism. It consists of a little gear on the
starter and two reduction gears, the second of which is on the crankshaft and
has a collar that projects into the flywheel.
When this is rotated by the
starter it carries three case-hardened rollers forward until they jam in the
slanted cavities of the flywheel when the engine is turned.
What I think happened was
that the last reduction gear picked up cold stiff oil and carried it to these
rollers and they stopped getting a "bite". I decided that if this
problem happened again the thing to do was to put the bike in fifth gear and
push it backwards a tad. This would rotate the flywheel backwards and tend to
jam the rollers.
A few weeks later it
happened, I did and it worked!"
J
im also gave some of the
reasons he likes the VISION, "I think the VISION is a great bike. I like
its large capacity gas tank, the heel rests, the place for my knees to fit, the
good mirrors, the eager engine, the 1985 (!) styling, the flat comfortable
seat and on and on and ...
Hope I haven't bored you too
much. Yours truly, James D. Gentry."
Not at
all. I hope to hear from everyone
again. Please write soon.
Now it's only fair to tell
you a bit about myself. I bought my VISION May 5, 1984 and have since put on
18,000 miles of commuting and touring. I belong to the AMA, the SRRA (Sierra
Road Riders Assoc.) and the Ft. Ord Fog Busters Motorcycle
Club. 1 am a civilian, my wife Mary is in the U.S. Navy and we ride our '82
VISION with the Fog Busters on many poker runs in the SRRA.
My other interests include
Ham radio (KF6X0), science fiction and folk guitar.
We love our bike and have
tried a few changes on it. Our favorite modification is a touring saddle from
Corbin. I put aircaps on the fork, but frankly they
don't hold enough air to be reliable. I tried an Easy Streets luggage rack to
hold a trunk but that was less than successful also. Next rack (on order) is an
Amco.
A Touring Elite on the rear
and a 110/90 Sport Elite on the front has eliminated the "bicycle"
handling of the stock tires.
In eighteen months I have
tried three different "fairings". A simple handlebar mount windshield
worked, but I wanted more. Next I tried Yarnaha' s Sport Fairing and was very pleased with the way it
looked. Now I have Rifle's Sport Fairing and I am very pleased with the way it
works (looks allright too)"
That's it for now, fellow Riders of VISION. Ride easy
and remember, letters, letters, letters.

Riders of Vision
Newsletter No. 2 February1986
Happy New Year and welcome
to the second issue of our newsletter! I ‘d like to
start this issue with a BZ for our U.S. Navy Rider of Vision #21 Bruce Rodgers
(Bravo Zulu is “Navy Talk” for congratulations on a job well done). Bruce
submitted two technical articles for our newsletter and was responsible for
sending us the FOR VISIONS ONLY catalog from Dyersberg
Cycle Corral.
Speaking of new members, we
have tripled our membership since the publication of “FYI” in “Road Rider” and
“New Clubs” in “Rider” magazines for January.
……. As I write, we have over 90 Riders of VISION on our membership roll.
Care and Feeding of a VISION
Welcome to 1986 and the year
that your VISION gets another year older or have you
been following Yamaha’s recommended service procedures? (Bruce discusses the
normal maintenance that should be done, and that the Yamaha
and the Haynes Workshop Manuals will “provide a very good PMS [Planned
Maintenance Schedule] for you”)…….
Kenny Steinberg (RoV#17)
writes: “Maybe other members have solutions for the only problems I have.
First, I have found excessive helmet buffeting on the highway with the original
screen on the full fairing. Second, I find the 1983-height bars a bit too low.”
RoV#10, Karl Retzlaff answers: “One modification I did to the bike was
to cut the windshield down about two inches. I traced the original shape of the
shield two inches lower using a compass with a felt tip pen in it. I then took
an acrylic knife – used for cutting plexiglass – and
scored the line until it was deep enough to break the piece off. I used sandpaper
to smooth the rough edge down. Now the buffeting is all but gone.”
Karl says further that he
has very few complaints about the VISION
"The
main one being the carb lag and the fact that, in my
opinion, it's geared too high.
It would be nice
if the bike could be geared to turn, say, 4600 RPM instead of the 5300 it does
at 60 MPH."
Our infamous
carb lag we will take up soon. For now I can tell you that Cycle Corral has the
"Euro Gear Set -- increases top end by seven mph, drops rpm by 500 rpm,
can be installed in one hour (factory Yamaha parts) -- $125.00", according
to their For VISIONS Only catalog. Yes, this catalog is worth having! Blair
Strain, RoV #11 suggests how to cure another common ailment of the VISION. Oil
leaking on the left side near the sender. According to my dealer this was an
unofficial (but well known) problem particularly in the ‘82s. She saws,
"My leak was fixed only after I told them how to do it and to do it right!
"To
solve the oil leak you must clean all the oil off the wires (inside and outside
the cover) and pack silicone rubber around and between the wires. The best way
to do this is to remove the case (get a new gasket first) and use Yamaha Bond
4 to smooth onto around the case and gasket."
She also
mentioned the stator problems we discussed in the first newsletter. For the
newcomers -- the new replacement stators solve the problems. Check with your
dealer to determine which one you have.
Jim Gentry
(RoV#22) says: “You high milers should get another bike to ride for profit and
save the VISION for fun. I’m serious. In my opinion the VISION is a collector’s
item ’s item now.”
Bruce Rodgers
contributions are at the beginning (on maintenance) and at the end of
Newsletter 2: Curing Vision Lag.
There you are
going down the road or at the stop light and for whatever good reason, you want
to dump the clutch and grab a handful of throttle.
Generally,
what happens is your VISION starts to move a little and then the tach hits
between five to six thousand rpm and the ol’ VISION wants to snatch your socks
off. Am I right?
Well, no one
in their right mind can argue with the power delivery from six to ten thousand
rpm, but getting to the proper zone can sometimes be a trying experience (or
you're an expert clutch slipper).
If you own an '82 XZ55ORJ, what you're experiencing
is VISION lag.
The reason
it's happening? Your engine is getting too much air when you jerk the throttle
plates open. It takes time for the fuel to be drawn from
the “well" known as the fuel float bowl. After the initial lag from 1500 -
5500 rpms the air that is passing through the carb venturies is of sufficient
velocity that the fuel gets drawn up in proper proportion for the engine to
take off like the Vee it was meant to be.
Yamaha
realized it had a problem with idle stability as well as low-speed and
mid-range performance. Yamaha sent to all its dealers a Technical Bulletin
(M83-003) dated Jan. 1, 1983, subject: XZ55ORJ Intake System, Modification
(kit).
Basically, the
kit consists of a new top for the air filter box, which now has a vacuum
diaphragm, controlling the proper amount of airflow into the filter and two
new jets.
The jets are: main
jet for the front carb and a larger pilot air jet for the rear carb. The part
number for this kit is 70391-10093-00, Intake System Modification Kit and the
dealer cost is $66.96. Unfortunately, some of us did not have this kit
installed on our bikes prior to delivery and we didn't know enough about the
problem to complain at tune-up time to the dealer.
You say you
bought your bike less than a year ago as a left over?
You're in
luck!
In the same
tech bulletin it states; "Warranty will cover the installation of this kit
for all XZ55ORJ owners who complain of poor idle stability and low speed
performance". So what are you waiting for?
For those of
you who are in the same boat as me, I'm going down to the local Yamaha dealer
and shame him into installing this kit.
If you are
fortunate enough to already have this modification or are riding an '83 VISION
(XZ550RK) but still experience some VISION lag, Stuart Cooper recommends the
following steps.
1. Synch the
carbs.
2. Raise the
float levels (both) to 37 mm.
3. Install one site larger main
jets.
4. Install one
size smaller air correction jets.
5. Adjust HO
and CO to proper settings.
6. Last. If
there is still some hesitation jack up the accelerator pump by shimming the
spring with small flat washers.
Stuart Cooper
recommended that a Yamaha dealer install the modification kit, but if you're
feeling froggie (or mechanically inclined, go for it with the excellent Yamaha
Factory Service Manual for $19.95, or the Haynes Manual for about $11,95. I
want to thank Stuart Cooper of Dyersburg Cycle Corral, Keep on with your
VISION. Bruce L. Rodgers, RoV#21.
The 7-page
Newsletter 2 ends with the contribution of Mark Tuttle Jr. (RoV#68) that the
1983 36 mm carbs of the RK fit right on the ’82 RJ model, use the modified air
box or the original ’83 airbox,
Ride easy,
riders of VISION

RIDERS
OF VISION
Newsletter No
3 March 1986
Surprise(!)
and welcome to the third issue of Riders of VISION Newsletter.
First thing
this month is club business.
We are now
almost 180 members strong and still growing, thanks to the free advertising in
Rider, Road Rider and Cycle World magazines. Your letters to the club are
increasing and show a strong interest in an active organization. Requests for
patches, pins and other items we don't have are also increasing.
To really
increase our membership roll however, we need more advertising and publicity.
To show and offer more to the membership, we need a more solid financial basis
to operate from than voluntary contributions.
According to
your letters you are willing to pay club dues of ten to twenty dollars a year.
As I said
before, I won't determine dues -- but you have told me it's time to do so. This
is asking a lot for such a young and small club. We also must realize that we
will lose some of our members because of this. Your letters convince me that
this is something we have to do if we want to thrive as a club. Therefore,
membership dues for the Riders of VISION shall be $10 per year. You may pay for
up to three years in advance. If you have ever wished for an opportunity to be
a Life Member of a club when it was first forming (and inexpensive) this is it.
Life Membership to the Riders of VISION shall be $45.
To save
confusion at the bank, Please make out checks to Paul Robinette, with a memo on
the check that it is for RoV dues.
All
memberships shall be dated from April 1986. This offer will be open for the
next three months. An accounting of funds shall be published in the Riders of
VISION newsletters.
Any money you
have already contributed may be used towards your annual or Life membership.
(We have a complete record of contributions.) The funds shall be used for
operating expenses, advertising and financing club materials such as patches,
pins, tee shirts etc.
Treasury
Report for January and February Month Balance
Donations Expenses $
00.00
Jan.'86 $ 00.00 $20.00 $ - 20,00
Feb.'86 $96.00 $82.26 $ - 9,26
I don't have
exact expense records for 1985, but we have broken even between donations (all
on record) and our expenses. Having dues will strengthen the treasury to the
point where we can buy pins, patches and other goodies for ourselves at a
reasonable cost. Eventually, I hope to
see the newsletters printed as a bi-monthly tabloid with photographs. We
need a membership rate of about 1000
members in order to make this feasible.
I also hope to
see regional Riders of VISION ride-ins!
California
Easter get-together
I'd like to
take this opportunity to invite any RoVs who can make it to California, to
attend the Sierra Road Riders Association Easter Run, March 30. I will be
riding with the Ft., Ord Fog Busters (on my VISION of course) and would be
thrilled to have any of you as my guests. Sign--in fees are tentatively $4.50 a
person and include a metal run pin from the SRRA. This is a family outing with
an Easter Egg Hunt, games and prizes for adults and children, at the Allen Witt
Park in Fairfield, Calif. There won't be a poker run, but there will be a lot
of fun! Trophies will also be given out for long distance riders ... must mail
in their sign-ins in advance if over 500 mile, ...
While this is
not an official RoV function, I hope to see some of you in person!
Drop me a
postcard if you're going to be in the area and I will call you about getting
together and the last minute details. For those of you just too for away to
even think about this, Happy Easter to you and yours. Rest assured, we will be
thinking about you. We'll let you know how this works out in the next newsletter.
Yamaha Family
Affair run scheduled for June
Robert E.
Lawyer, RoV #4, would also like to get together with other Riders of VISION.
Bob and his wife Diane write, "We will be attending the Yamaha Family
Affair in Pigion Forge, Tenn., June 13, 14 and 15. We would sure love to see
other VISION owners attend. In 1984 there was only one VISION there (to our
knowledge). In 1985 there was only two VISIONs participating. If there is
interest in having a VISION "Ride-In" we would love to help with the
preparations and such.
"Hope to
see at least some of you in June!

Hope some of
our RoV’s can participate in the Yamaha Family Affair and send a letter for our
newsletter' (yep, letters, letters, letters!)
See you at the
races!
Another opportunity for RoV to get
together in June is reported by Kevin Flates, RoV#104
"If you
put out another letter before the motorcycle races in June at Ellart Lake
(part badly
readable) so that any members can reach me."
The
following true story was submitted for the last newsletter, but we just didn't
have the room that it deserved.
A faded
VISION
by Jim
Gentry, RoV #22: Saturday, and the day dawned crisp, clear and cool.
The BMW was
tucked in the shop for its 5000 mile check and the VISION demonstrated its
eagerness to go by starting, even though the temperature was under 40 degrees.
It was 30 miles to work and time was short, so away we went smoking it down the
road at mostly 70 mph with the MAC straight-through mufflers snarling their
song.
The trip
ended uneventfully and all that remained was for the VISION to return me home
that evening.
Frost
covered the seat that night, but again the VISION cranked without its starter
drive pawls slipping and we began our homeward run. The first 15 miles passed
with only a few "misses" which I guessed were telling me to switch
the fuel selector to reserve. A few miles later there seemed to be a slight
loss of power which 1 attributed to pulling a hill.
Cruising two
lane blacktop at night requires much mental concentration, but eventually a
red light registered in my mind. The red light was coming from the VISION's
dash, of course. My automotive experience caused me to think "alternator',
with the emphasis on 'will I make it home?".
By the time
I made the stop sign at Sniders Cross Roads I knew my eight valve Vee twin was
very sick, but why?
The oil
level was OK, but starting up about an hour after cool-down produced much
knocking sounds from the engine.
So, fellow
Riders of VISION members, for the time being my VISION is dead!
As I said,
this story was submitted some time ago and I haven't heard front Jim since, I
hope there is a happy ending to this hard-luck story. He also wrote about bis
experiences with the MAC exhaust system for the VISION.
MAC Exhaust
system short-sighted for VISION?
Flash! My
MAC exhaust system arrived Jan. 6, 1986. I do not recommend the MAC system. I
would have gladly paid more for more quality!
Here's what
was wrong.
The bolt
holes in the flanges that hold the front pipes to the engine were not lined
up. I spent several hours working with them. I finally had to take a moto-tool
and grind out a hole to get the pipes to fit properly. Almost cross-threaded a
bolt more than once.
There were
no instructions or suggestions with the system. One bracket was missing. One
non-part was included. The bolts for the clamps were too short!
No new
gaskets for the front cylinders were included. Mine leaked after installation
and it was necessary to undo all my work:, make gaskets and re-install the whole
mess.
I had to
drill holes in the non-part to make a bracket that holds the rear of the
mufflers together.
It appears
that the rear wheel cannot be removed with the mufflers in place.
(other than
all of the above, the system is OK, but noisy. One thing for sure, it's hard to
believe a VISION engine could make so much power with all the restrictive
garbage inside the stock mufflers!
Sounds like
Jim's new year has gotten off to a poor start. Sure hope things have improved
by the time he reads this newsletter!
We are still
getting a lot of questions about the VISION's stators from RoV.
Stators: Out
with the old, in with the new!
Tom Berry,
Rider of VISION #87 writes, "Concerning the stator problems that I was
blissfully unaware of, what are the symptoms? Is there a particular production
date or serial number after which the better stator was factory installed? My
warrants expires this coming May and I'd sure hate to have to buy a stator
myself."
Bill
Stevenson, RoV #84 says the stators fail because of heat. «My stator burned up
on a trip to Canada-last summer. the new stator is being protected by more
frequent oil changes (every 1000 miles) and in hot weather (over 80 deg.F.) by
using SAE 50 oil. VISIONs run hot and the stators are destroyed by the heat. On
warm days I stop to fill up the fuel tank: and the gasoline boils!"
Hank
Daniels, RoV #116 was told that some VISIONs came with bad stators. "Like
all members, I am very happy with my VISKIN ('83) and plan on keeping it a long
time.
"The
only problem, I've had was a burned out stator while 1 was down to Daytona for
Pike Week last year. I rode down front Pennsylvania and part way through Pike
Week when my battery went dead (1:00 in the morning, a block away front Boot
Hill Saloon, no less).
"I bump
starting it, I got back to the hotel. I called the local Yamaha shop in Holly
Hill and they took me right in. The point is, the mechanic said this was the
second VISION he had with a bad stator. There was also a rider there with a
Venture Royale (Double VISION?) that had a bad stator too!
"I
talked to a Yamaha rep. at the display test set-up at the
race track: and he said some VISIONs did indeed come through with bad stators.
"I had to
put a used stator in my bike because there were none available new in a 100
mile radius of Daytona and I had to ride the bike home. lt
cost me $180.00 to fix the bike, by a used stator and replace the ruined
battery.
"1
called Yamaha Corporation when 1 got home and after much discussion, they
agreed to install a new stator at no charge. When it was all over, I had a bike
with a new, updated stator and I was out $180.00. Yamaha wrote me a letter
stating that they would do no more on this matter."
The
information that I have about the alternator stator is that there is no tech
bulletin specifying serial numbers of affected bikes. The old stators
fail because the protective coating on
the windings break-down under use. The average miles on the affected bikes is
from 4,000 to 7,000 miles when the stator fails.
There are no
warning signs. You just can't start or go. The average price of repair is about
$180.00. The new replacement stators have a different coil insulation that does
not break down under normal usage. Some riders report that Yamaha will replace
the old stators when they fail even though the bike is out of warranty. That is
one of the reasons to support your local dealers, they can help you deal with
the corporation if they want to. The 1982 models are more likely to be
affected, but as Hank reports above, the '83s may also have bad stators.
Same problems
lend themselves to creative solutions. We've had some feedback about handlebars
from Riders of VISION.
Getting a
handle on the VISION
Vince Wright,
RoV #49, a photographer by trade decided the best change to make to a VISION
was to modify the handlebars. "For touring, the lean forward position with
a full fairing was tiring for me, even with the higher bars of the '82 model.
"So, I had a machinist cut the aluminum bars, make a block that can bolt
together, giving me an upward and backward lift to the bars. Just guessing
here, but it probably moved them back almost three inches, and up about two
inches, which also spreads them out. It is about the limit for the stock
cables, bet it makes all the difference in the world for plowing across the
Nebraska landscape!"
Henry
Schroeder, RoV #41 also wrote about getting a grip on the VISTON.
'The
handlebar and footpeg locations on the '82 and ‘83' VISIONS are not the save.
The '83 had lower bars and higher pegs than the '82. It is possible to change
bar or peg locations with the appropriate parts. "The bars require only
the upright posts. The pegs require the complete peg-bracket assemblies, the
brake pedal and the shift link rod. The swap is fairly simple, but wilt require
the removal of the fuel tank if putting '82 bar posts on the '83. It will be
necessary to re-route some of the cables to avoid having them pull when the
bars are turned to full lock.
"There
are quite a few new '82 chassis parts in West Coast cycle dismantlers.'
Torn Berry,
RoV #87 offers to save the trouble of looking for parts.
"Tell
Kenny Steinberg, RoV #17 that I'll trade my '82 height handlebars for his '83
style bars. Those of us without fairings (or with small ones) could use a lower
bar'
Also, if he
wants to trade his slightly more rear-set '83 footpegs, brakes, brake lever and
shifter lever for the '82 style, I'd be happy to oblige him. We might both be
more comfortabel"
Tom also
commented on modifying windshields.
VISIONs in
the wind
"Karl
Retzlaff was lucky indeed that he didn't ruin his windshield by 'snapping' off
the previously scored upper portion.
'A better way
is to mark the line to cut, mask over both sides of the shield with masking
tape, retrace the line and very carefully cut along the line with a sabre saw.
"The key
here is taking it easy; that is cutting slowly. You will get some slight
melting which is easily dressed down with a file. Repolish the new edge with
400 or 600 grit wet-or-dry sandpaper and water.
"Voila!
Lower windscreen!"
Again we get
to hear from RoV #84 Bill Stevenson. 'I have the factory fairing on my '82
which is like that on the 1983s. The helmet buffeting is my only complaint.
Karl Retzlaff's fix of cutting it down is going in the wrong direction for me.
"There
is at least one company in Florida that makes a replacement windshield with a
higher airfoil than is stock. Has anyone tried this fix?"
Well, uh,
haven't heard anything like that yet, but RoV#85, Buzz Glaesemann of N.Dakota
may have the best idea yet ... 'Thank you for accepting me as a member and for
the very interesting and useful information contained in the first two
newsletters.
"I am 57
years going, have been riding for about 10 years and presently own a XS1100F
and a '83 VISION. I like my 1100 for the long-haul but my VISION is the most
fun and relaxing to ride.
"I have covered
about 80,000 miles in 27 states so-far by motorcycle and one of my goals is to
ride to and in the other 21 continental U.S. as time and funds permit.
"I too
have been bothered by wind buffeting from the stock fairing windshield. Lacking
a taller replacement windshield, I purchased a Laminar Lip from Laminar Inc.,
P. O. Box 12332, 1514 Fairview, Columbus, OH 43212, telephone (614) 488-5158.
(lt is advertised
in Cycle World for $29.95.)
"I tried
attaching it according to the enclosed instructions, but this was not
satisfactory to me. I attached it with two screws on each side instead of one,
using short lengths of small rubber hose for thick washers between the
windshield and attachment.
"I find
it works well for me and worth the investment.
"I sure
hated to drill holes in the stock windshield though. "I also removed the
windshield and reattached it with silicone sealant between the screen and
fairing body. This eliminates the water and dirt which formerly found their way
between them. Keep up the good work. Yours truly, Buzz--."
Thank you,
Buzz and everyone who writes with such nice compliments (and good
information). Robert Stone, RoV #15 also wants to pass out some compliments.
"Greetings
from, the mountain state (W. Virginia)! 1 really enjoy receiving your
newsletter almost as much as riding my VISION. I was getting just a tad worried
because 1 thought maybe you were having trouble with the club.
"I guess
I should of written, eh? (yep.)
"I am
the proud owner of a black '82 model VISION. 1 cannot express the joy I have
had riding this bike. This makes about the twelfth bike I've owned and nothing
can compare with it.
"I would
also like to give a special thanks to the guys at Bub's Yamaha here in Beckley,
W.V. They have really helped me in sprucing up my bike's looks and performance.
They have a great service department.
"If you
get a chance, mention these guys in your next newsletter. "Ok Robert, but
only if you tell us (in detail) what the guys at Bub's Yamaha did that
obviously made you so happy!
Henry
Schroeder, RoV #41 has one more contribution for us.
Beating the
heat on the VISION
"A
common problem on water cooled bikes is for the fuel tank to get uncomfortably
warm on hot days, especially while riding slowly in traffic.
"This is
caused by hot air from the radiator flowing up under the fuel tank. Blocking
the hot air, while allowing cooler air from the front of the bike under the tank,
will let the tank run cooler.
"I used
1/16 inch neoprene sheeting cut to fit the triangular space between the upper
frame rails, the steering head bracing and the opening between the steering
head and the airbox.
"It is
held in place by tie wraps (See the diagram.)"
Areas to be
blocked off to reduce fuel tank heat ///////

Thank you,
Bill, for the interesting idea.
Questions,
questions and questions!
One of the
important things about RoV letters is questions. Your questions guide the
direction that future newsletters follow. Here are some questions for
consideration by all Riders of VISION. If you have some answers, share them
with us.
David Klever,
RoV #60 writes, "Mg VISI()N is still 100 percent stock as it left the
dealer. However, I do have some questions and concerns.
"At 800
miles, coolant started to leak: out of the hole on the right side of the
crankcase cover. My local dealer replaced the water pump seals. I did not
detect any leaks during the summer, but a month after I put it away for the
winter, I noticed coolant starting to seep out of the hole again. Has anyone
else had a similar problem?
"Also,
the cooling fan will not run until the temperature gauge needle is bumping up
next to the red zone. My dealer says this is normal. However, it is somewhat
unnerving to be stuck in traffic with the needle almost in the red! "Has
anyone tried to put a radio on an '83 model?"
Bill
Stevenson, RoV #84 also has some questions.
"I am
particularly interested in brakes. Has anyone done any testing to know what
works best? Mark Tuttle, might you share the details of the four piston caliper
modification?
"Another
area of interest. Has anyone played with cam timing? This modification could
result in cooler running and more low-end torque at the expense of same peak
power at high rpms.
"Has
anyone tried a sidecar?"
Pat Carmon,
Rider of VISION #56 queries, "Has anyone tried a Tracy Vortex fairing? I
would like information on fit, looks and protection since I am considering
purchasing one.
"I would
also like to hear from any Riders of VISION who have installed the Spec II
exhaust system. From a fellow motorcyclist and Rider of VISION, Pat."

promised in the second newsletter, a listing of VISION articles as compiled by

RIDERS
OF VISION
Newsletter No
4 June
1986
Welcome to
the Summer Riders of VISION newsletter.
The first
item of news that I have for all of you is the fact that my wife and I are
moving to Guam this summer. This change of address was not anticipated for at
least another year.
1 had hoped
to be able to do more with this organization before 1 left, but sometimes life
is like that.
This will be
the last newsletter that 1 edit. Hopefully, this won't be the last newsletter
that I see!
Now is the
opportunity for you to become an editor. Send me your request for consideration
as soon as possible, as I will be leaving in July. You do not need prior
experience (though it is helpful) or a lot of fancy equipment (though it
probably wouldn't hurt) to edit Riders of VISION. The members send more than
enough material to issue the newsletters.
1 use a Model
4P computer with enhanced Sripsit for word processing and Profile 4 Plus for
record keeping. An inexpensive DMP105 printer does the original which I then
have "printed" by a copy shop. Frankly, the quality can stand to be
improved -- but it has kept the costs down.
If you have
compatible equipment I will send you the disks with the data and newsletter
files. Otherwise, I will supply you with
hardcopy of all the material. After selecting you as the next editor of
RoV I will also send you the balance of the treasury that belongs to Riders of
VISION.
lf you don't
become the editor, don't panic! We have many talented people in RoV and I am
sure that one of them will step forward to keep this organization going.
Frankly, (again) I feel that this will be a good change for RoV as a new editor
means new ideas.
In the
unlikely event that no one steps in to carry on (a lack of vision that I doubt)
it is my intention to donate the balance of the treasury to the 1986 Pony
Express Ride for Liberty, in time for the cross-country relay team of bikers,
Sept. 2.
On that date,
the riders will leave the last stop of the original Pony Express route
(Sacramento, Calif.) to collect the money raised across America. The first
relay team will collect a check from the governor for the money that California
riders raised, before recreating the PonyExpress concept and riding to the next
state line. There they will meet that state's chosen Pony Express riders, who
will continue the run to that state's governor, and so on across the nation.
The last six
riders will meet in New York City near the end of September, where the
saddlebags and checks will be collected and presented to the Statue of Liberty
Ellis Island Foundation.
If you would
like more information about this Ride for Liberty, write to: Pony Express Ride
for Liberty, c/o Patti Nelson, P.O. Box 199, Cleverdale, NY 12820 or call (518)
656-9207
Bravo Zulus!
The next
order of business is to give credit to those who have been most helpful to me
as the first editor of Riders of VISION. Tom McKaskle, Rider of VISION #1 for
the original idea and encouragement. Bruce Rodgers, RoV #21 for his many
submissions of material and ideas. James Gentry RoV #22 for his excellent
letters and all of you Riders of VISION with
the vision to believe that our favorite motorcycle from Yamaha is worth
the time and trouble to form this organization.
I would like
to especially thank mg wife Mary E. Robinette who helped me with the tedious work of licking stamps and the
other onerous chores of publishing a newsletter.
As my
associate editor, she was also responsible for any correct grammar and spelling
that may have slipped into the newsletters!
Our financial
report for this gear follows.
Treasury
Report for January - May 1986: there is $ 696.34 in hand (I do not include the
Dues paid and Expenses, XZv2)
We now have about
118 Paid memberships. We have had a total of almost 400 inquiries and have sent
out about 400 newsletters in response to them. One set of newsletters to
England and another set to Singapore!
The Red-Faced
Rider of VISION
I sometimes
have to admit to making an error, as evidenced by the following letter.
"Dear
Paula, Oops, sorry about that Paul, but you know how it is when you're called a
she, when you're really a he. To give you some background, I'm a 37 gear old
banker who's married and likes to ride.
"Here's
a couple of bucks to help with expenses; your doing a good job, but remember –
he, not a she. Please correct this in the next issue, Thanks." Signed,
Blair Strain, RoV #11.
My apologies,
I'll quit trying to guess on some of the names that I'm not familiar with!
The unique
form of our VISIONs always elicits comments from people looking at our bikes. In the next letter, from an industrial designer
in New Jersey, Larry Simms, RoV #345 we get a peek: at how the VISION's form
came to be, as well as the reasons for the lock of VISION's from Yamaha.
The sad saga
of VISION 1982
"Dear
Paul, Enclosed is a copy of the letter from GK Design ...
They sent me
10 complex but fascinating pages on their Oriental design philosophy. Any
interested readers may contact me for more information.
"Dear
Mr. Simms, Thank you very much for your kind letter ... We are glad that you
enjoyed our exhibit at the Worldesign conference. 1 have enclosed herewith a
copy of the panel texts. The idea of relating the Buddhist philosophy to industrial design is our original. The Buddhist tone comes from the fact that our
president, Kenji Ekuan, was a Buddhist priest in his younger days before he
became a designer.
"Your
reference to the Yamaha motorcycle was quite interesting. We (GK Industrial
Design Associates) have been designing Yamaha motorcycles for the Japanese,
U.S., European and other markets for over 25 years, and needless to say, we
were responsible for developing your favorite 1982 Vision as well. "There
are basically two reasons why the Vision was not a commercial success. One was
that the styling was too advanced for the time. Secondly, its cost performance
wasn't outstanding enough to justify its initial high price.
"The
1982 Vision was designed to be a performance bike, and our goal was to make it
into the most advanced super sport bike in terms of both styling and riding
performance. Unfortunately, because so much time and money was invested in
developing the engine that the other parts of the bike couldn't be fully
developed to match the quality of the engine. And the results showed in the
races.
"The
difficulty of developing a performance bike, unlike a touring bike, is that it
has to be NUMBER ONE and duly proven at the race tracks. Number two is simply
not good enough to the consumers, it seems. No matter how expensive the bike,
if its performance proves that it's NUMBER ONE, the price is justified, and this
is reflected in the sales. Though Vision is a very good motorcycle, it failed
to reach that status. When the bike was redesigned the following year into a
touring version, it began to sel1.
"So,
that's the sad saga of Vision 1982." Signed, Marlene M. Horiuchi,
Coordinator, Overseas Department.
And that is
the word from Tokyo, Japan.
Interested
readers may write Larry Simms, RoV #345 at: 300 Gorge Road, Cliffside Park:, NJ
07010.
Larry also
wrote RoV about the problems associated with storing machines and some of their
possible solutions.
VISION
storage problems and solutions
"Internal
combustion engines," Larry writes, "and the machines that house them,
hate to be stored. Yet, most VISION riders bought their machines after a
substantial period on the shelf. I compounded the problem with a year's hiatus - with no preparation - after the first year of
operation.
"The
biggest problem I had is that rubber and plastic started to fail - mostly the
petcock valve and the O-rings on the coolant pipes. The coolant pipes are a bit
tricky because much of the right side engine must be disassembled. I was 800
miles from home, so (I) let a dealer tackle it.
"After
searching three dealers and two recyclers for a replacement petcock, I finally
found a guy who showed me the microfiche exploded view of the part. There's a
$4 rebuild kit which is easy to install which completely remedies the problem.
"Incidentally,
when this valve fails, no fuel flows in the main or the reserve petcock
positions. You can keep running indefinitely on "prime" position;
Provided that you remember to switch the valve off when you park, and that you
remember you're operating with no
reserve!"
A report on
the "Euro Gear Set"
Rider'-of
VISION #27, Vernon Cockle writes, "Dear Paul, just a short note to let you
know that since my last letter to you, I purchased and installed the "Euro
Gear Set" from Dyersburg Cycle Corral.
"Upon
receipt of the new clutch basket and primary gear, I calculated the gearing
change to be about five to six percent. My tachometer did confirm this (after
installation). The rpm difference at 60
mph is about 300rpm. This means that with stock tires, the VISION will turn
about 5000 rpm at 60 mph. I also have a 120/90 Dunlop Sport Elite on the rear
which lowers the rpms an additional 150 to 200. (Now I turn 4800 rpms at 60
mph.)
"The
labor involved for installing these two new components is quite easy. It
involves the following processes:
1. Drain the
engine oil and coolant. Remove the right engine case.
3. Remove the
clutch release plate and all the individual plates.
4. Remove the
clutch basket (a 30mm socket is needed).
5. Remove the
primary gear.
"On the
fifth step it should be noted that the gear bolt should actually be loosened
with the clutch still assembled and the
bike in gear with the rear wheel locked.
A 30mm socket is needed.
"The new
clutch basket and primary gear are easily installed and the engine then
reassembled. Be sure to properly install the "clutch release plate".
An arrow on this plate should align with
the round mark on the "clutch center".
Spec II
exhaust system for the VISION
There has
been a lot of inquiries about the Spec II exhaust
system for
the VISION. Vern Anderson, RoV #115 reports, "Pat Carmon, RoV #56 asked
about the Spec II exhaust system.
"I have
installed the system on my '82 VISION. The Spec II exhaust fits perfectly!
Bolts right on, with no filing or bending. The exhaust note is louder than
stock, but for me, not objectionable.
"As for
performance, the engine feels stronger at low to mid rpm. At 6,000 to 8,000 rpm
it feels flat, then comes on good to redline. I have the airbox fix on mg
VISION. Spec recommends changing the main jet on the rear carb to the same as
the front, which is a 122.5. If someone else has used the Spec II system and
has further suggestion as to jetting, I would like to hear from them.
"I have
a Yamaha Sport Fairing for the '82 VISION in perfect condition I will sell for
$50. Call me after 5:30 p.m. CST at (312) 627-5422." Signed, Vern
Anderson, RoV #115.
Stopping the
VISION
Jerry Hester,
RoV #112 in Tenn. wrote us about brakes, among other things.
"In
answer to Bill's question (RoV #84), Performance Machines' caliper brace assembly
is excellent. It equals or surpasses mans OEM double disk setups. Be sure to
shim the unit as instructed. Being aluminum, the torque figure for mounting the
assembly is eight to 10 foot/pounds, which varies from Yamaha's recommendation
of 25 foot/pounds.
"I had
to call Performance for this information. Do not try to use the stock brace
line, replace it with a Russell braided steel unit. For best results install a
Telefix 65-15-28 lork brace and # 1108 fork springs as recommended by Tuttle.
The Fox Shock is worth the expenditure.
"After a
good deal of experimentation I would like to make the following
recommendations. Use Suzuki's formula for fork oil, 50% 10W-30 motor oil, 50%
transmission fluid. Check with a Suzuki dealer for details. Front tire,
Metzeler #33 Lazer 100/90 and rear tire Dunlop H391 190/90. I've bested same
pretty hot machinery with the above modifications in our mountainous terrain.
"Now for
my question, does anyone have a seat pan or Corbin Gun Fighter Saddle for sale?
Would like to hear from other VISION riders in the Southeast." Signed,
Jerry Hester, RoV #112, 1602 Rustic Homes Lane, Signal Mtn., TN 37377, (615)
265-0148 (days), 886-3074 (nights).
Thanks, Jerry
for the contribution. Now's the time for me to say, "that's it, folks and
ride easy, Riders of VISION, and thank you all for your support. I'll be
looking forward to the next RoV newsletter by your new editor!

RIDERS OF
VISION NEWSLETTER#5 SEPTEMBER, 1986
Welcome
riders of Visions to the new Riders of Vision. I look forward to working with
all of you to make this organization something that works for all of us. This
newsletter will be short, partially because I haven't had enough time to get
the systems in place to make the paper work run smoothly, and partially because
I haven't received much information from members yet to put into it. This is
to be expected when a club moves from one coast to the other as quickly as we
did.
NEW BUSINESS
In an attempt
to streamline my job and maximize our resources as a club, I'd like to try to
implement a few standards. I know what your thinking, new guy comes in and gets
power hungry- starts making a lot of new rules.
If these
guides seem out of line, drop me a note and tell me so. Any alternatives you
people come up with that make sense only make my job easier.
1. It seems
only fair that the newsletter be sent to paid members. It's production costs
are high enough and our income as a club is so small that I think this is a
necessary evil. I'm not sure how Paul was handling this, but unless you members
think this is wrong, this will be the last newsletter I'll circulate to unpaid
members.
2. Paul said
that all dues were to be scheduled for April payment. I would like to set up a
schedule of quarterly payment with payment due the first day of the first month
of the quarter. I'll even send you all reminders if you will take a minute and
let me know when you paid your dues. Paul was unable to give me this information.
3.I've
received a lot of requests for back issues, enough, in Pact, that the cost of
producing them and postage is significant. I've decided that it would be only
fair to charge $2.50 for each one. Any less would be less then paid members
have paid; any more might make them unavailable to some members.
4.I'd like to
put together a photo album of members and their bikes. This volume would be for
posterity, obviously. I don't see any feasible way to allow all of our members
to see it; if you do see a way, let me know. In any event, send in your
pictures those of you who haven't already. Maybe when we are able to include
color photography in the newsletter, we could use the photos for that purpose.
OLD BUSINESS
There is some
confusion as to how much dues are. Paul chose $10 a year and $45 life as
reasonable amounts and this choice seems to be popular with the membership. Once
things settle down a little, I will be able to tell if this will generate
enough income to do the things we may want to do in the future.
CORRESPONDENCE
I received
three advertisements aimed at the entire membership. The first came from
REGABOOTS in California. They make a rather complete line of motorcycle spats
and have offered a 20% discount off of their normal price range of $32.00 to
$46.00 to all members. An evaluation of their product can be found on page 92
of the May, 1986 issue of CYCLE WORLD. Their address, in case you want more
information is: REGABOOTS 9016 Wilshire Blvd. #345 Beverly Hills, CA 90211 Their phone number is (213) 932-1895
The second
one came from DRESSER JACK'S MOTORCYCLE ACCESSORIES. They carry after market
Gold Wing parts, ultra-sonic animal warning devices, and offer custom patch and
badge production for clubs. The first two items may be of dubious worth to us;
the last item may be one we would be interested in in the future. That address
is:
DRESSER
JACK'S MOTORCYCLE ACCESSORIES 111 E. Oklahoma
Ponca City,
OK 74601
The third ad
came from R.J. Leather sales. Jon Barletta promises at least a 10% discount for
all members on tires, batteries, fork braces, luggage racks, hard and soft
luggage, lights, helmets, leathers, grips, turn signals, and a great many other
items. The address is:
R.J. Leathers
Sales 105 W. Mahoning Street Punxsutawney, PA 15767
Patrick
Carmon of Pittsfield Massachusetts wrote in about our old problem of defective
stators. Yamaha sort of left him hanging about his stator, indicating that he
would have to foot the cost himself. I called Yamaha's Customer Relations
department myself and asked (as a man representing 400 customers for what it
was worth) and I think they may have given me the official poop. The man I
talked to said that they would pay for parts only to replace stators in bikes
that met any of these criteria:
- that the
bad stator was causing emission problems in a unit bought from a California
dealer
- that the
bad stator was in a bike less than 5 model years old and with less than 12,000
on the odometer.
I was told
that this was what Yamaha was telling their dealers, and that they were telling
everyone else to talk to their dealer. I understand that the new stators are
made differently to handle the heat problem. If you wish to lock horns with the
beast yourself, the address is:

what happens, and GOOD LUCK!
Ray Baldwin
write to say that he was leaving the club. He found a great deal on a new
Interceptor and used his Vision as partial payment. The man he sold it to all
but toteled the bike the second day he had it, so we say farewell to Vision
#577.
Eric Larson
from North Bend, Oregon write in to ask two questions; I pass these questions
to you. The first concerned the mounting hardware for the National Cycle Plexifaring.
The hardware he got will not allow the fairing to sit back far enough. Is there
other hardware available? His other question was about crash bars. If you have
seen any that fit this bike, or can help with the fairing problem, write him at
the address below and then drop me a note so I can tell everyone else.

Brian
Champagne of Bakersfield, California write in looking for an
answer to a
problem. "I have unsightly whitish stains all over my engine that look burned
on coolant or some sort of coating burned off. I've tried S.O.S. pads, engine
degreaser- nothing even mars it. HELP! It's ugly!" Got any Ideas? Write
'em in. Brian also asked about T-shirts. I'll be checking into this soon.
Robert Burget
of Hayward California wanted to pass along his ideas about several after market
items he has tried.
Michelin Hi
Sport tires- 110/80 front and 130/70 rear: great traction, they make you want
to lean over far enough to drag footpegs, and they don't wear out as fast as
some folks say.
Dunlop Sport
Elites: O.K., but require a lot of warm up.
Fox Shock:
pricey, but high quality and adjustable and rebuildable. Sure beats stock.
Ferodo Disc
Pads: noticeable improvement, cheap.
Reynolds
brake lines: great improvement for $40, '82 riders can forget about dual disks!
Progressive
Suspension fork springs: No more front end dive, air caps not required!
Progressive
Suspension rear spring (blue): not recommended, this is way too stiff for any shock
body. If your girl friend weighs 300 lbs., call me and you can have mine for
free.
Chip Baker of
Port Townsend, Washington write in to say that he has had excellent results
with his Metzeler Marathon (rear) in the 120/90 size.
Don Nuttall
from Richmond, Virginia passed along some changes to his bike that may help
some of you.
"Roller
bearings from a 650 Yamaha smoothed out the steering at low speeds.
A steel shim
under the center bolt of the top triple clamp solved a problem with movement in
the steering head. The problem felt just like loose steering head bearings but
was caused by the center bolt not holding the top clamp tight. A manual switch
was installed parallel to the fan thermoswitch. This allows manual override on
hot days in city traffic. The engine doesn't run high in the temperature zone
when the fan is turned early.
Luther Leake
asks "Does anybody have any easier methods or tools for getting at the
spark plugs? Removing the front plug is almost a 45 minute job! Also are there
any better ideas for getting at the valve tappets?" If you can help him
with either of these very real problems, write me. He also mentioned the Vetter
Sting, a fairing that he has had a good time with and one that comes color
matched to the Vision.
I did some calling
around and found the Sting very hard to come by with a rectangular headlight
opening. Vetter has stopped making them.
Along these
same lines I was curious about what the status was of either of the standard
fairings for the Vision from the factory. I called the main office at Yamaha
and found out that the sport fairing, while not being made anymore, is still
available in black and silver through a dealer at a price of the dealers
choosing. The full fairing found on the '83 model has to be ordered in pieces;
they were net even sure that they had the pieces to construct a complete unit
in one color. If you were looking for one through a dealer, forget it. If you
have one on your bike new, don't drop it!
LAST BITS
We have our
own bank account new; this should make it easier for both you and me. Our
balance right new is just under $400. I'd be happy
to send a
copy of the books (such as they are) to any member interested.
Don't forget
to write in when you paid your dues, and remember that most of the information
for this newsletter comes from the membership, so write!
Those who
haven't paid their dues....... well?
Send photos!
Be on the
look out for our Christmas issue newsletter . Any ideas on making winterizing
an easier task? Write them in!

RIDERS
OF VISION
NEWSLETTER #6 DECEMBER,
1986
I've lived on
the east coast in cold or fairly cold climates all of my life, so I know as
much of the disappointment of putting my bike up for a while as anyone. Perhaps
this year was worse than usual, partly because I finally wore out the marginal
rear tire that came stock on the bike giving me the perfect excuse for putting
a good Metzeler tire on in it's place, and partly because of the weather.
Between June lst and September lst, we in Maine received only 17 days of
complete sunshine. That's bad even for us. 1 suppose it's a tribute to the
tenacity I have for the sport that I managed to put 400 more miles on my RJ
this year than either of the other two years I've owned it.
A lot of you
know the scene. It's about 10:30 on a Saturday morning in midNovember. By
sheer will, you've somehow gotten the temperature outside up to 38, maybe 39 degrees
and you decide that with no wind and the sun shining you'll go for a ride (my
cut-off point is 50 degrees normally, but in mid November standards go out the
window.) It takes only 3 or 4 miles for two things to become remarkably clear.
The first is that with the sun so low on the horizon, it seems only to shine on
those parts of the road that are the least fun, leaving your favorite sections
in a deep freeze. The second is that you remember that on an unfaired bike it
makes little difference if the wind is blowing or not. You've never lost the
feeling in your hands so quickly as you have on this ride. It's not fun
anymore. A little voice is telling you "It's time!"
You pull in
and go through the "de rigeur" of putting the bike away for 4 1/2 of
the longest months of the year. Once your done, it suddenly hits home! You
panic, and run inside and renew all your motorcycle magazine subscriptions.
Indian summer invariably comes one week later and no one can understand why
you've so irritable during this time.
Soon, the
first snow comes, and a whole plethora of sports and scenery that goes with it.
It's a wonderful time of year. Skiing, the holidays, warm wood fires, all of
these help you to forget. They don't cure the urge, but they help.
OLD BUSINESS
I'd like to
try to explain my plan for dues payment a little better then 1 did in the last
newsletter. I read it again and I was even confused. Each member will be asked
to pay his or her dues again once a year only. Instead of everyone paying in
April as Paul suggested, I will send each of you a reminder each year at the
beginning of the quarter in which you last payed your dues. So, if John Q.
Public payed his dues on May 5, 1986, I would send him a reminder on or around
April 1, 1987 to pay his dues. If he had payed his dues on November 12, 1986, I
would send him a reminder that his dues were due sometime after October lst but
before December 31st in 1987. Does it make sense now?
I realize
that a number of the members will be disappointed with what I have to say, but
I felt it was necessary to abandon the ROV number system. I understand the
pride with which some of you held these numbers, but from a more practical
standpoint, they were doubling my workload. This kind of a system would only
work if all members used their numbers whenever they corresponded with me. I
could not have membership information catagorized by number and also by name. I
hope you will forgive me if this isn't what you want; I will still keep a
record of the original numbers for posterity, but new numbers will not be
issued.
NEW BUSINESS
I've been in
contact with George Henshaw, an ROV member who runs a small custom printed
sportswear shop in Cincinnati. He has been doing some work on a design for a
T-shirt, and since I like to think we take care of our own, I'd like the club
to patronize him for shirts. What 1 would like to know from each of you is this
- which of these two options would be more appealing. He can produce the design
on inexpensive white T-shirts for a cost of $5.95 plus two dollars for
shipping. He can also put the same design on 100% cotton long sleeve shirts
with up to these color graphics for $12.75 plus two dollars each. These prices
are only good if the club orders more than 48 shirts. Since I'm not sure if the
members will order 96 shirts, I don't see how we could have both. If I hear
from enough of you, I'm sure that we could work something out.
So, when you
get the chance, let me know how many shirts we'll need. This information will
let George and I know what to do. By the way, George said that while he had a
design, he was open to any suggestions you would care to send him. His address
and phone number are:

CORRESPONDENCE TECHNICAL
Bruce Rodgers
wrote in with some suggestions for re-jetting carbs after the installation of
the Spec II exhaust system. "Main jets 122.5, air jets 130, idle mixture
screw 3 1/2 turns from seated position. I have no lag anywhere in the RPM
range. A note of caution, if the carbs aren't in synchronization, nothing will
work to get rid of the lag."
On that same
note, Andrew Biehle has done extensive work on his carbs and has gone to a
great deal of trouble to send me information on what he did in great detail. I
present you with a broad overview of what he did and if this sounds like
something you would like to try, you can get in touch with him.
First, Andrew
worked to better balance the two carbs. "I found out that my back carb was
not set up right to begin with. My pilot air jet was #135 instead of #130. My
main gas jet was #120 instead of #127.5.
I enlarged my pilot gas jet from a #60 to about a # 80 pilot gas jet by
drilling a set out with a #69 thousands drill bit. I changed my pilot air jet
to a #145. This let my bike start better." He further altered his power
nozzles on the tops of his carbs. "The power nozzle is the pipe_ in the
top of the carb where the air jets are. It works by vacuum, when air is pulled
down the carbs, gas is pulled up the pipe and into the carb. The pipe or nozzle
has a hole in the side that works as a jet. Just one of my power nozzles had a
hole in the side, so I took the tops of my carbs to my dentist. He was nice
enough to drill the same size hole in my other power nozzle............. This
better balanced my carbs and gives them the gas they need on the top end and
open throttle.
Andrew goes
on to explain a method he used to cure all hesitation on his bike. "The
main problem with the carbs is the top
opening is a lot larger than the inside barrel that goes to the intakes. The
power nozzle works from vacuum, so when the top opening is made smaller, closer
to the size of the inside of the carb, this gives you better vacuum all the way
to the top of the carb..... When you give it throttle the gas is there, because
of better vacuum so there is no delay in response and good power all the way up
the RPM range." Andrew narrowed the top of his carb by constructing and
installing two pieces of sheet aluminum as diagramed below:

Andrew also
replaced his air intake box for two individual air filters of his own design.
He sent me some color photos and the filters are very attractive.
I wish the
club had the resources for me to reproduce all the information Andrew sent me
so that I could pass it along.
It's obvious
that he spent a lot of time on his intake system and probably knows as much
about it as anyone. If you would like a copy of what he sent me, send me $2.50
to cover the cost of copy and postage and I'll send it along.
I'm also sure
that Andrew would be willing to answer any questions you may have. His address
is:

Jerry Fisk
of Botavia, New York wrote in with what
sounds like the best solution for Brian Champagne's problem of blemishes on his
engine cases. He has tried with good success the three steps below for
refinishing the cases.
1. Zip strip to
take off the rest of the clear coating from the factory.
2. wet sand
with 400 - 600 wet paper, lots of soap and water or buff with woollike buffing disc using Simichrome,
Mother's or Blue Magic.
3. Recoating
with clear coating #PNT 65000-04-00 from Yamaha
Thomas Oswald
from Grand Island, New York sent me a note about a problem he had and cured.
Perhaps it will help some of you.
"On two
seperate occasions I had problems with the Vision losing power when I opened
the throttle. It felt as if I ran out of gasoline. The problem was the rubber
tubes running to the YICS. The tubes take some sharp bends and they are not stiff
enough to prevent collapse when under vacuum. Yamaha replaced two of these
tubes. A friend came up with a better idea. For $3.00 I bought rubber gas line
(the same inside diameter as the YICS tubes) and 4 hose clamps. With a
screwdriver, socket and socket extension, I installed the tubes in about 10
minutes without removing the fairing. No more trouble."
I got a note
from Joe Kamplin of San Francisco, California about a shimmy he had in the
front of his bike and what he did to solve the problem. "I settled on the
air assist front forks. When I first tested them I found 3 psi in the left leg
and 8 psi in the right one. I evened them up to have exactly 6 psi in each leg.
'That ended the shimmy problem - for about three weeks, when the shimmy
returned. My summation on the above is that the air chamber seals aren't
sealing properly, and it would take a long trial and error period to rectify
the leaks. But I would suggest installing a cross-over tube into each fork leg,
so you're getting the exact same pressure in each leg, and whenever the shimmy
returns, pump a little more air in."
Gerald Toby
from Kissimmee, Florida wrote in to warn us all of a problem that may arise
with the kick stand kill switch. "Here's the story ...... every once in a
while, it would stop for about a second or two and then keep running. The
headlight, tach, and motor would shut down. Turnsignal and horn would still
work. There was not a set way or rhythm for this and no one knew what it
was." After a time, Gerald found that the source of the problem was the
kick stand. "I had to play with it 2 or 3 times before it would start.
Time to go to my dealer for help. There we agreed to replace the relay, not the
switch. A new switch would probably do the same thing......... Her's the
kicker! The bike ran like a new bike! Better acceleration, better running, much
less carb hesitation....... Gerald even claimed that his engine smoothed out
enough to make both mirrors much more useful.
Jerry Hester
wrote in to pass along a method for eliminating vibration in your throttle
grip. "you will need after market grips such as GRAB-ONS that use a
plastic cap to cover the end of the bar and two packs of Daisy BBs. If you have
already installed this type of grip, simply remove the cap carefully. Turn the
bar to the
Ieft and pore the BBs into the throttle handle (it's hollow and made of
plastic), install grip cap in normal fashion. The BBs will not interfere
with throttle operation, but will
dampen the majority of the buzz."
Karl Ratzlaff
wanted to know Don Nuttall's address and phone number so he could get more
information on Don's steerinq head fix:
Don Nuttall,
2306 Dragonfly Lane Richmond, Virginia 23235
1 have no
record of him being a paid member, so you might ask if he is interested in
doing so. I think 1 sent him a copy of the newsletter, Karl, but I never heard
anything back.
M. L. Le Duc
from Webster Texas dropped me a line to make some recommendations about tires.
He claims that the Metzeler ME33 and ME99 are not good choices for the '83
model, saying that they were too wide for the wheels and exhibited a tendency
to fall into turns and wobble on deceleration.
I have these
tires mounted on my oven '82 and find them to be very good. Perhaps there are
enough differences between the ergonomics of the two years to explain the
discrepancy. Le Duc does go on to highly recommend Continental TK22 100/90V18
and TK44 120/98H18 "RC" "rally compound" BMW replacement
tires which you can order through Dennis Kirk. He also recommends Golden
Spectro 4 20W50
Jim Lockridge
from Redmond,Washington wrote in to ask if anyone has found a place on a Vision
to mount a Kryptonite lock without interfering with attachment of luggage. If you know of a way,
let him know at:
10602 171st
Ct. NE Redmond, WA 98052
Mr. Le Duc
wrote again asking if anyone can answer either of these questions:
1. What are
the beginning and ending serial numbers for the RK model?
2. How many
'83 RK models were built?
He was able
to-find out that Yamaha has no warranty registrations for 98 RK's out Yamaha
would rot answer any other questions. If you have this information, please forward
it to:

For those of
us still looking for a good looking fairing that doesn't cost an arm and a leg,
Larry Beals wrote in to tell us that Greer Sport Fairing is in the process of
designing two new fairings for the Vision. Larry also would like to see a group
from our club at Aspencade next year. If you are interested, you can reach
Larry at (518) 885-1643. Might be a good place to show off our new shirts.
Dick
Richardson from Omaha, Nebraska sent me some information on some products he's
tried, the most interesting being the Cyclear "Cutlass" clear fairing
"which I am 75% happy with . It blocks the air out does swirl the noisy
air into the drivers area."
Tommy Manping
from Keystone, Florida wrote in to let the membership know that "I live
just 90 miles north of Daytona and thought maybe we could throw some sort of
get together on or around Daytona Bike Week. I live on SR100 which is a road

Julius Bere
wrote in with some information on a new exhaust for the Vision.
"Wolf
Racing Products Inc. has just produced a new exhaust system for the Vision. I
am the first person in North America to run with these pipes. It is a two
(two?) into one pipe that is tucked tight into the bike and sweeps up high in
the back. The pipe runs up the right side of the bike. The system gives the
bike a real sport look and sound. The bike also seems to be quite a bit quicker
on take-off and acceleration on the straights. Gary (the president, Gary Wolf)
said it should not require any rejetting. It also gives you easy access to the
oil plug, and you retain the side and center stands. The exhaust is all black
with an alloy canister on the back. The system will retail for about $250.00

LAST BITS
- To those
members living in other countries, please remember to send your dues and other
payments in American currency, or at least send an amount that is the same
value as it's American counterpart. Thanks.
- Be sure to
tell the club what model year you are referring to when you write in with
technical information.
- I talked at
length with a business in Alabama that doubles as a salvage yard and rebuilder
of electrical components, like stators. They told me that they could re-wrap a
vision stator for about $60.00 if you sent them the core. They said that they
would rebuild the stator to withstand much more heat, thus solving the problem
for the future. According to the person I talked to, stators are really a weak
link in a lot of japanese bikes. The worst offender as far as they were
concerned was Suzuki. They did tell me that the Vision had a particularly bad
stator from the factory. They claimed that they could fix the problem.
They also
said that they had a lot of used Vision parts for sale. They also said that
they would send me information on exactly what they could do, address, prices,
phone number, etc. I'm still waiting, and since I got there names from a long
line of leads, I didn't bother to keep the original note containing their names
or number. As soon as they get in touch with me, I'll pass the news along. I apologize for not being more thorough the
first time 1 had them on the phone.
-Enough of
you have asked to hear a little more about me that I've decided to indulge you. Those of you who aren't interested may skip
to the next item.
My name is
Clark Stivers, I'm 30 years old, I'm married, and Marie and I have one child, a
girl of some 11 months. My Black '82 Vision is basically stock (braided steel
brake line, Metzeler tires, perforated front brake rotor by Spec II) and I
purchased it in May of 1984. 1 bought it because the price was right ($1700.00)
and I was ready to get back into motorcycling after a 3 year hiatus to finish
school. I owned a 1976 Honda CB550 four before that, and a 1977 Honda CB400
four before that. As soon as I become rich, I'll buy a number of other bikes to
go with my Vision. Right now, I couldn't ask for a much better bike for what I
do with it than the vision.
- My wife and
I are in the process of buying a house this month, so I have been busier than a
long tailed cat in a room full of rocking chairs. I use this as an excuse for
all of the typos in this newsletter. I
figured that you people would want the newsletter sooner with a few mistakes
than later as perfect.
- No one
write in with tips for winterizing, so 1 will tell you what 1 do with my bike when I put it up.
10 minutes
before I shut it down for the last time, I put a gas stabilizer in
the tank.
After I shut it down, I fill the tank to completely full, and pull the drain
plug on the crankcase. If it needs a new oil filter, I put it in. I fill the
crankcase with new Castrol GTX 10W40. I pull both spark plugs, and pour about
a tablespoon
of motor oil in each cylinder. I crank the motor over a number of times with
the plugs still out to distribute the oil over the cylinder walls, then replace
the plugs. I squirt a stream of WD40 down each exhaust pipe and plug
the ends with
rags. I top the battery off with water if
it needs it, and then
take the
battery into the house. I usually take
the time to wipe the unfinished parts of the bike off with a rag and some light
oil (WD40) to establish some sort of film between the metal and the air. I do
this last step because I live less then 100 yards from the ocean. Every bike
I've ever owned has responded well to these few steps.
I guess thats
it till March. Have a very Merry Christmas and ride safely, Riders of vision.

RIDERS
OF VISION NEWSLETTER
#7 March, 1987
If
there is nothing else one can do with so much snow on the ground, one can think
about things, contemplate how to make things better. Or at
least more complicated. I'd like to share one of the ideas I had
recently for improving the clubs files, hopefully transforming them into prime
sources of information. Right now, whenever I get questions like "what
information do you have on after market exhausts?",
I have to admit "not much." I can pass on some consensus of the
membership on what they recommend for some of the obvious choices, i.e. SPEC
II, MAC, but I would rather be able to give the inquirer a fairly comprehensive
run-down of what is available. The same for fairings, tires,
and high performance parts and procedures.
This
would require a great deal of time and effort for one person, especially if
that person needs to spend time already on keeping the "office" open
and producing a quarterly newsletter. What I would like to do is to ask for
volunteers from the membership to take one of these categories and run with it.
I
would need this information in a form easy to file and equally easy to
disseminate, something along the lines of a catalogue. What do you think?
If
you are interested in any of these categories, let me know. Then, get started.
Track down leads, collect ads for products you know will fit the Vision, call
or write companies that produce these products, call people who may be racing
the Vision in any form (I know of a couple), sniff out any information that may
be
of use to our members. It should be a lot of fun, I only wish I had the time to do it.
OLD
BUSINESS
I
have not authorized Octograph to start printing
shirts yet since I have gotten only about 15 or 20 letters from members saying
they ware interested. As you
may remember, the prices we were quoted were good for 48
shirts or more. The bulk of the requests were for the better long sleeved
shirt, so I'll assume that this will be the shirt we will want in the end. If
you would like one, please let me know ASAP.
NEW
BUSINESS
I've
received a couple letters from Ted Elzinga, a life
member, and a producer of another newsletter on a different subject. He would
like to see the newsletter be reduced to 78% of normal type size. This would
cut the cost of printing, and possibly make handling at mail time easier. Paul
tried this with the first newsletters with limited success. Ted claims that
the reduction Paul tried was poor because of the dot-matrix print, and that
this print is of good enough quality to stand such a reduction without
sacrificing reader comfort. What do you think?
Ted
also sent in a graphic piece I plan on using for our letterhead. An example of
it may be found on the next page. I think it's an excellent choice, and a fine
bit of work. Thanks Ted.
CORRESFONDENCE
I
got a letter from Diane Deutchman of Orlando,
Florida. She wanted to know of any
information about increasing engine displacement for more horse power to
compensate for the loss due to drag on her Vetter Quicksilver. I recommendded that she try to find another way to find
horsepower in her Vision since upping displacement was expensive. If anyone has
any suggestions they should let her know. Her address is found below. She also
found tight low speed maneuvers very difficult on the Vision; the bike seems
unstable and she wanted to know if anyone had any suggestions for tire choice
that might help.

Nuttall wrote in and made it official. He's a member
paid in full. He
also commented about Tom Oswald's problem providing us with
another cure. While Tom replaced his YICS hoses with substitutes, Don had his
dealer place coiled springs around the original hoses to prevent collapse.
Welcome to the group, Don.
Don
Vanecek of Blair, Nebraska wrote in with a problem
that we ALL face during the coarse of a riding season.
Road grime on the front of the engine and the front header pipes. I just
happened onto an add for a possible cure for this
problem. There is a product called S100 Total Cycle Cleaner that is available
through cycle dealers and parts places. It's a spray on, hose off affair,
though it is supposed to be safe for all sensitive surfaces including plastic,
alloy, rubber, paint, even bearings and O-ring chains.
Don
also wanted us to know that he has installed a Vetter Bullet fairing on his
bike and goes on to say..."it doesn't work very good.
If I put it up high, the disturbed air hits me right at helmet level and the
fairing doesn't look right. If I put it low, it looks nice and protects my
belly button just fine, not much else.
Brad
Hawes wrote me to let us in on an easy and very useful improvement. He replaced
his headlight bulb with a 100 watt unit and claims vastly improved night
Vision. Several members have written in with this simple swap, out Brad was the only one who coupled the suggestion with a warning.
He says that occasionally the combination of low and high beam will blow the
fuse, leaving you with no light. Brad also wanted to know what other members
recommended for quick detachable good looking hard saddlebags, and what, if
anything, other members had found for a comfortable long distance seat. His
address follows, and whatever suggestions you may have, send them into me too.

Peter
Spirka sent me a note and asked me about where and
how to get the European Touring Gear set up. I couldn't tell him because I
didn't know. I do know that some of the members out there have installed this
unit on their bikes.
Please
send whatever information you can to me and I will pass it along.
Joseph
Anastasio from Hartford, Conn. wrote in with his
experience with the SPEC II exhaust system. "After
much work with re-jetting and air box modifications, I must report that the
only good thing about it is the sound! The fit was perfect but that was about
it. While it did not have any pronounced lag anymore, it also did not have any
power either! Any mods to improve extreme top end
(8-10000 rpm) or low to mid range (4-6000 rpm) would significantly reduce power
in the rest of the range. The best I could get was smooth power throughout the
range (3-9000rpn) but still less than stock.
I
am now back to stock and enjoying my "new" power." You'll find
his SPEC II system for sale in the next section.
We
have one member living in Singapore. His name is Andrew Chan, and he wrote in
with some suggestions and a couple of questions. He runs Pirelli MT 28 tires in
100/90 front and 120/80 rear sizes. He says they work very well in all
instances except painted lines on wet pavement. He also recommends FIAMM Gong
horns to replace the emasculated stock units. He wanted to know if anyone could
help him get a hold of a Saeng Quantum fairing, and
also what if any information he can get about the difference between tubeless
and tubed tires. Which are standard? His bike came
fitted with Bridgestone tires with tubes, and this jibes
with what his owners manual tells him the bike needs. Andrew also has a Haynes
Owners Workshop manual for the bike which calls for tubeless tire as standard.
My own Vision came with tubeless Bridgestones. Now I’m
confused. Anyone got any ideas? Andrews address is:

David
Kimmey of North Miami Beach, Florida wrote in with
warnings about the fuel system. "I had a real problem with premature
rusting of my tank. I had gas line clogs from rust particles, the whole mess.
I'd recommend Vision owners check their tank carefully for rusting and, if
deterioration is found, invest in one of the several tank coating kits."
David also advises that..."Vision owners should switch the fuel tap to
reserve once in a while and (while the motor's running) drain about 1/2 pint of
gas out. I've noticed some nasty junk coming out which I wouldn't want to enter
my carbs."
Our
very own carb man Andrew Biehle
wrote in with another suggestion for better breathing and more horsepower. He
says that replacing the YICS system with a hose that runs from one cylinder to
the other directly will increase horsepower.

LAST
BITS
-
First, I'd like to thank all of the members who thought enough to send me
Christmas cards. I only wish the club had the funds to reciprocate. Maybe next year.
-I've
talked twice with Eddie Wilbanks o£ Memphis, Tenn., a
man who builds high performance Visions for racers. He's put together a 750
Vision that Jimmy Adamo is going to try out this
month. If he likes it, he will campaign it this year in the Pro-Twins races.
I'll let you know what happens. I'm planning on being
at Loudon N.H., the weekend of the 20th and 21st of June in
case this bike is there.
The
last item in this edition of Last Bits is a recopy of one of the magazine
articles about the Vision. Some member came up with this idea before and since
this was a short newsletter, and since I've started putting together a
collection of these articles, I thought I'd start including one of these in
future issues of the newsletter. I'll do this as long as there is room in a newsletter to do it without making
it too long, and as long as I can get permission to. Unti1 June, keep the shiny
side up, and lets see if we can have a Vision contingency at Loudon in June,
OK?
Take
some of the enthusiasm that comes from warm weather and sit down and write
Riders of Vision a letter. There are
some of you out there that I've never heard from.

YAMAHA
XZ550 VISION Cycle
World Test
At
first it didn’t make sense, why Yamaha would produce another fast, sporting
550cc street bike when the company already makes one of the fastest and best
550 sports machines.
Besides
the question of why try to beat the Seca 550, there
was the question how to beat the Seca 550.
Yet
there, on display at Yamaha’s new model show, was the Vision, also known as the
XZ550RJ, though the name on the side of the bike only said Vision.
There
were no clues to the size of the machine, except it didn’t look tiny and it
didn’t look huge. It could be a 500 or a 750; it was within that range.
Yamaha
made bold claims for the Vision. It would be faster than the Seca 550, a bike that could run through the standing-start
quarter-mile in the 12-sec. Bracket. Yet it only had two cylinders. So why did
this Twin weigh more than the 550 Four. All the numbers did was confuse.
Finding
out the why and how of this motorcycle requires more than a quick look at
simple numbers. It requires a close look at the insides of the unusual engine
and, finally, it requires riding the bike to have any idea why Yamaha would
make such a machine.
Look
at the existing Yamaha line of street bikes and the Vision seems out of place.
There are no liquid-cooled Yamaha street bikes in this country, Yamaha engineers
explained during introductions of the M-series of four cylinder machines that
they didn't need four valve heads to make plenty of power, that two valves per
cylinder works just fine, thank you.
The
results of their efforts have been marvelous inline Fours, air cooled, with
narrow engines because of auxiliary shafts and clever designs making the
engines compact. The V-Twin engines introduced last year seemed more designed
by marketing demands than engineering ideas, though they work well enough. They
provide no clues to the Vision's design.
Look
far enough into Yamaha’s past and all of the Vision's features pop up. There
was the V-Four prototype shown to the press several years ago, much like the
Vision but with two more cylinders tacked on. Yamaha was a leader in using four
valves per cylinder with the TX500, a bike that also had a counter balancer
shaft to control vibration, all this a decade ago.
Putting
together all the textbook tools of good engine design on a 70' V-Twin of 550cc
has produced a machine that isn't like the 550 Seca.
It’s bigger but faster with more power produced at every engine speed. It is a bike that can be ridden
leisurely or at racing speeds and it can make its rider happy at either speed.
It is, in sum, a better bike than the Seca.
What
makes it a better bike is the engine. Having gone through a dozen years
of Twins being
replaced by better Fours,. it's surprising to find a
Twin that’s superior to a a Four. Having fewer
cylinders, doesn't make it faster or lighter or better handling, necessarily.
But because the engine is so highly over square, with a
80 mm bore and a 55 mm stroke, it doesn't suffer the usua1 shortcomings of few
cylinders.
Older
Twins had long strokes that limited engine rpm and small bores that limited
valve sizes and engine breathing.
Even
most of the multi-cylinder motorcycle engines have avoided highly oversquare designs because the transverse Four cylinder inline engines would be too wide for that
design. It's been various Twins that have most exploited this over square
design, and none has taken as much advantage as the Honda CX500 has until now:
Unlike
Honda’s liquid-cooled 500cc V-Twin, the Vision is not big and plush. Its a tighter,
faster, more sporting machine that still manages to be a pleasant touring
machine between visits to the road course.
The
Vision also manages to produce more power at every engine speed, from idle to
10,000 rpm redline.
like those other combinations that work so well, roads and
racing. motors and wheels, the Vision's over square
design and Vee configuration are no accident. There
are reasons for them being together. 1n the Vision's case the 70 “ V makes the engine more compact than an equivalent
parallel Twin would be. The cylinders don't stick straight up, and the engine
hangs dons down below the frame, so extremely tall cylinder heads can be used
without interfering with the frame geometry. Having no height limitation,
Yamaha has built the Vision engine with unusually long connecting rods and
with a very narrow angle between the valves, both design tricks that help the
engine work better but could not be easily done if the engine weren't this
particular shape.
Perhaps
you've heard that long-stroke engines provide greater torque than equivalent
sized short stroke engines. The latest word from engineers is that short-stroke
engines with long connecting rods can provide just as much torque, plus lower
piston speeds and more peak power, and that's what the Vision has. Connecting
rods are 122 mm between centers for a 2,2 : 1 ratio of rod length to stroke, a
much higher than average ratio.
The
narrow valve angle is another unusual design that results in better port shapes
and a better combustion chamber than valves mounted at a broader angle. The 36’
included angle between valves provides maximum benefit for combustion chamber
and port design and the tall heads aren’t a problem on this bike.
In
many ways the engine of the Vision shows automotive influence in its design.
This shouldn’t be surprising because Yamaha bas been building auto engines for
many years, using its facilities on the most sporting Toyota models. What the
Vision does not copy are Yamaha's existing V-Twins, the XV750 and XV920. The
only similarity to the existing designs is in the cam drive, which uses
anti-lash sprockets on each end of the crank to drive the overhead cams. The
layout is the same, though no parts are interchangeable.
At
its most basic characteristics, the new Yamaha is different than the previous
V-Twin. They don't even rotate the same direction. Last year the air-cooled V-Twíns came out with engines that spun opposite the
direction of the bike's wheels; this counter rotation, Yamaha said, reduces
vibration from the 75' V engine. That's why the Virago and XV920 didn't need
any counterbalancer shaft, explained Yamaha. Now
there's a 70' liquid-cooled V-Twin Yamaha with the engine spinning the same
direction as the bike's wheels, equipped with a counter rotating balancer shaft
and it's mounted in an entirely different steel tube frame. And, just like the
last V-Twins from Yamaha, this new engine works.
lf anything, the new V-Twin works better than its big
brothers. It was designed to produce more power for its size than the larger
V-Twins. Those bigger machines weren't designed to compete head-to-head with
the fastest 750s and 900s in terms of performance, so they didn't have to be
tuned so highly. The Vision is not afforded that luxury. Yamaha decided the
Vision would compete directly with any four-cylinder machine for performance
and the differences between the Virago-style engine and the Vision engine are
there to support more peak power.
The
first key to more power is higher engine speed. The larger V-Twins only needed
a 7000 rpm limit for adequate power. That lower engine speed meant they could
be balanced for a narrower rpm band and didn't need the counterbalancer
shaft. For the Vision, maintaining a smooth-running engine over a very wide rpm
band meant the addition of the gear-driven counterbalancer.
Vibration forces increase dramatically with increased engine speed and, even
though the Vision engine is smaller than the Virago engine, the 10,000 rpm
redline makes the counterbalancer a useful addition.
Mounted at the front of the engine, forward of the crankshaft, it is driven by
a spring-cushioned straight-cut gear. Its' 25 mm shaft diameter spins in
large ball hearings at both sides of the vertically-split cases.
At
the ends of the massive crankshaft are full-circle plain hearings. Because the
cases are not split horizontally, the Yamaha has one-piece main hearings that
are pressed into the cases. Machined surfaces on the inside of the cases act
as the thrust bearings. The bottom end, like the rest of the Vision engine,
looks big and strong. Main bearings carry a 45mm shaft. Connecting rod big ends
are 45mm, the small ends 20mm. The rods ride side-by-side on the single throw
crank, the forward cylinder being mounted on the right-hand side. At the top
of the connecting rods are 80mm pistons, with slight rise and cut-outs in the
top for four valves. There is little unusual about the cast aluminum pistons,
the top ring being coated, the second compression ring being a taper and the
oil control ring a three piece ring.
Power
is transmitted from the one piece crankshaft to the multi-plate clutch by straight-cut
gears. The clutch is normal Yamaha, with eight plates and a wave washer to
smooth engagement. It is located on the right hand side of the transmission
main shaft, which rides on large ball bearings.
There
are no auxiliary or extra shafts in the Vision. The transmission consists of
the main shaft and the countershaft. The driveshaft takes the power from the
left hand end of the countershaft through bevel rears. Because the engine spins
in the conventional direction, that is clockwise when viewed from the right
hand side, the driveshaft connects to the forward side of the countershaft’s
beveled gear. It would also be possible to take power off the aft-side of the
countershaft’s bevel gear and spin the engine backwards, as Honda is doing on
its V-fours, but either way seems to work well.
From
the bevel gears power runs through a small U-joint and back to the driveshaft
in the left hand side of the swing arm. This is a different swing arm than that
of the Virago and uses a spring-loaded ramp-type shock absorber at the end of
the driveshaft, just ahead of the ring and pinion.
All
the gears of the Vision are straight-cut. The starter operates through an idler
gear to the generator flywheel. At the other end of the crankshaft there are
nylon gears to operate the water pump and other small spur gears spinning the
oil pump. The water pump has a small plastic impeller and ceramic seals. It
pulls coolant from the bottom of the aluminum radiator and pushes it through a
pair of chromed steel tubes, one running to each cylinder. Coolant
runs around the steel-lined aluminum cylinder and up though the cylinder
head, where it runs back to the radiator.
While
the bottom end is strong, compact and relatively simple, the top end of the
Vision is what makes all the power. It does so with lots of big valves spending
as much of their lives open as possible and with big, straight ports and little
restriction in the exhaust or intake.
Because
the Vision engine is highly over square there is lots of room for valves in the
pentroof combustion chamber. Yamaha has made the most
of this with a pair of 31 mm intake valves and a pair of 26
mm exhaust valves in each cylinder. To put this in perspective, the
valves sizes of a Kawasaki GPZ550 are 27 mm intake and 24 mm exhaust and there are the same number of valves in the four-cylinder Kawasaki
as in the two-cylinder Yamaha. On valve sizes alone the Vision has a breathing
advantage on its four-cylinder competition, a trick not often available to a
Twin. In addition the Vision makes more of its bigger valves by using
abnormally sporting cams.
Duration
of the intake cams in the Vision is 284’, exhaust cams are 276’. Overlap is
70’and lift is 8,8 mm for intake and 8,3 mm for
exhaust. The numbers are more extreme than those of the cams used in a GPz550
or a Seca 550, for instance. Duration is longer,
overlap is greater and valve lift is higher, all contributing to more peak
power because the valves open farther, longer, enabling more air to flow
through the Vision’s engine.
The
next closest 550 class bike to the Vision for radical cam timing and valve area
is Yamaha’s own Seca 550 with 268’ and 264’cam
duration, 30 and 26 mm valves and 7,8 and 7,1 mm valve lift that was the
largest the Vision engineers had to aim at and they hit it.
Because
the overlap is so great, a high 10,5 : 1 compression
ratio could be used without excessive compression pressure leading to
pre-ignition. Performance cams require high compression, generally, and this
one has it.
Besides
the extreme cam timing, the valve train is noteworthy for several other
features. Cam followers are normal inverted buckets, with the shins installed
at the top of the buckets, just under the cams. To hold the noise to a minimum
clearance between the bucket and the shims is reduced from that on normal
Yamaha’s with bucket-and-shim valve opening.
Valve
stems are slim at 6 mm, another feature reducing interference in the ports.
The
cams are the same on the front and rear cylinders. To tune the cams there are
cam sprockets with four holes, each hole being used on a different cam. This
way only one sprocket has to be produced. The cams ride directly in the
aluminum head and the cam cap. But each cam holding cap has a rubber plug in
it. Remove the plug and there is a hole in the cap. Turn the cams to the right
position and there are holes through each end of each cam. The purpose of all
these holes is to provide access to the head bolts. A long 8 mm allen wrench can fit through the
caps, cams and heads to the deeply inset head bolts. There may have been other
ways for Yamaha to fasten the head onto the cylinder, but this is a clean,
convenient system.
Silent
link-plate chains drive the cams and are tensioned by slippers and automatic tensioners. Instead of the common ramp-type automatic
adjuster, the Vision uses an adjuster with a serrated plunger held in place by
a locking lever. This adjuster is more resistant to backing out at high rpm.
Two
large exhaust ports in each head connect to twin header pipes, which connect in
the exhaust system before branching out into two mufflers.
The
length of exhaust systems on the front and back cylinders is much different,
the forward cylinder using long double tubes wrapping under the engine, the
back cylinder having a short branched exhaust.
In
the center of the V is the intake system. The carburetors are unusual for a
motorcycle, being a pair of downdraft, butterfly-throttle automotive-type carbs.
There
are accelerator pumps, and an enrichment choke circuit, plus a vacuum-operated
fuel pump mounted between the two carbs. Each carb has a 36mm barrel leading through a short tube to the
intake port that branches apart to the two intake valves. Because the liquid
cooled engine shouldn’t have a different operating temperature for the two
cylinders, it is surprising to find different main jets in the two carbs: the rear carb has a one
size larger main jet apparently due to the differences in exhaust flow.
Remember
the radical cam timing? Normally a motorcycle would suffer poor low speed
throttle response and power from such cam timing in exchange for the increase
in peak power. To compensate for that the Vision has Yamaha’s Intake Control
System, a small plastic chamber that connects to the intake port. This type of
intake reservoir was first used on Yamaha dirt bikes to good effect and now
comes to street bikes. It is a simple system with a small hose connecting a
two-chamber plastic container to the intake port of one intake valve on each
head. Having the YICS connect to just one of the two intake valves provides a
swirl to the incoming mixture as the waves of air pressure flow in and out of
the plastic chamber, improving combustion efficiency at low speeds. What makes
this system work is an absurdly simple little plastic container. It’s that
small gray triangle on the right hand side if the bike beside the carbs. It only weights a couple of ounces. It has no moving
parts, but pull it off and plug the holes and the Vision doesn’t run as well at
low engine speeds, so there must be something to it.
How
this engine is carried in the motorcycle is as novel as the plastic box or the
downdraft carbs. Until now motorcycle frames should
be a full cradle tube frame, a stressed engine tube frame or a pressed steel
backbone, usually with a stressed engine. The Vision has a welded steel tube
frame, but it’s not a cradle type. There
are no down tubes and there are no tubes under the engine. Instead, the
steering head is fastened to a pair of top tubes and a pair of bottom tubes.
The top tubes branch out to the sides and angle down towards the rear axle. The
bottom tubes also splay out, but they do not angle down very much, wrapping
around the sides of the engine before bending back. Onto the back of the frame
attaches the braced swing arm. Like the monoshock
suspension on Yamaha’s early motocross bikes, the top brace of the swing arm
pushes against a single shock mounted high in the frame, where it fastens to
the top frame tubes under the seat.
Look
at the photos of the frame and it looks simple. There’s a lot of good thinking
in this frame, the loads from the rear suspension are fed directly into the
backbone. It’s virtually a straight line from the …..the
swing arm, the rear part of the frame and up to the steering head. Next the
distance from the top frame tubes to the lower frame tubes is very short. This ads to strength and rigidity. The engine hangs from
this frame, feeding its torque and stresses into the swing arm pivot plate on
the frame and attached to the lower frame tubes at the center of the Vee right at the base of the cylinders. The narrow engine
can be mounted at the lowest possible position without forcing the frame out of
shape. Engine removal is made easier by a removable lower right hand frame
tube. It unbolts at the front and back not only for engine removal, but for
some engine service tasks.
On
the front of the frame hangs the aluminum radiator and
its electric fan. Where the radiator is mounted is important in the Vision’s
design. If Yamaha had stuck a normal set of straight-leg forks on the Vision
frame the legs would have hit the radiator any time the forks were turned more
than a few degrees off center.
The
normal approach would have been to stick the steering head another couple of
inches forward, which would have lengthened the wheelbase that much. For the
weight and size of this bike Yamaha didn’t want a longer wheelbase. That would
have slowed down the steering just that much more. Instead, the Vision has
trailing axle forks. The steering head and the front axle are just where Yamaha
wants them to be. The placement provides for the right steering
head angle and the proper trail. But there is greater than
normal offset to the triple clamps and the axle is behind the fork sliders so
that when the bars are turned to the stops the front fork legs don’t hit the
radiator. It’s a clever approach to an unusual problem.
Aside
from the position of the front axle and the rear suspension unit, the
suspension on the Vision is very simple. Fork design is normal telescopic with
no adjustment of damping, no air caps, and no anti-dive. Just plain old coil
springs and hydraulic damping, doing a good job of keeping the front wheel on
the ground and the handlebars controllable.
Just
as simple is the rear suspension unit, a single coil spring of variable rate
and a non-adjustable damper within that spring. Spring preload can be adjusted
to five positions by turning a collar around the shock body. Adjusting the
spring preload requires raising the hinged seat first.
Attached
to the ends of the suspension are lightweight cast wheels unlike any previous
Yamaha wheels. Having spent a year not getting used to the spiral pin-wheel
look on most Yamahas, the new wheel looks very good. It uses thin rectangular
shaped links between the open-center hub and the rim. It’s the open center that
contributes most to the weight reduction of these wheels. The spokes fasten to
an open hub with the large 11.8 in. single disk. In back the same design includes
a drum brake and splines for the shaft drive.
Using
a large single disc does not provide as much brake area as using two more
normal sized discs in front. It is Yamaha’s way to get the best performance
with the lowest cost and weight. The engineers back in Japan know they could
get better high-speed braking power and control with another disc, and that
would even braking loads on the front suspension so it didn’t bind when the
front brake is applied hard, but those are the compromises they have to make.
Another
important part of the Vision’s development is its styling. Yamaha has been
perhaps the most active Japanese motorcycle manufacturer in styling. Yamaha
Specials began a look that is still with us and that other companies are still
copying.
Then
came the Seca models,
extending from the futuristic Seca 750 to the
beautifully clean Seca 650. Now the Vision and the
new 400 Seca are branching into a different area,
with more angles and V-shapes.
Most
of the Vision’s styling emphasis comes from the gas tank. It’s a large tank
with a big, flat top and a combination of angles forming the sides. There’s a
crease in the middle of the tank creating a noticeable V-shape in the sides.
The bottom of the tank is lower than the carburetors, necessitating the
vacuum-operated fuel pump. The inner panel of the tank has to provide room for
the wide top tubes of the frame and the air filter tucked between the frame
tubes, robbing the tank of more capacity. Fortunately that hasn’t kept Yamaha
from expanding the tank so it contains a useful supply of fuel, and the styling’s just gravy.
At
the back of the tank is a small diamond-shaped cover, leading to the upswept
angle of the seat, ending in the wrap-around taillight. By using a moderately
sized 18-in rear tire and the unusual frame, there’s plenty of room for a deep
padded seat without raising seat height into the clouds. The slope of the seat
is minimal and doesn’t prevent the rider and a passenger from finding a
comfortable position.
More
angularity is found in the instruments and the rectangular halogen headlight.
The box-shaped instrument cluster includes a temperature gauge with the
speedometer and tachometer, but doesn’t have any of the more exotic array of sensors and blinking lights, a decision that meets
with our approval. All the various squares and triangles and V-shapes form a
tidy and compact motorcycle. Better still, it doesn't look like anything else.
The Vision is distinctive from any angle, with no borrowed shapes or pieces.
Many details on the Vision are similarly unusual in design and novel in their
own right. Large cast aluminum plates form the foot peg brackets and hold
things like brake levers and the mufflers. They are light and simple and fit
well on the Vision. Handlebars are another unusual design. There are several
multi-piece handlebars on motorcycles now, but most of them are add-on designs
with lots of parts and no adjustment. On the Vision the aluminum uprights
attach to the sides of the top triple clamp, forming part of the clamp. This
eliminates an additional handlebar pedestal and makes for an uncluttered top
triple clamp, into which is set the ignition switch and several warning lights.
And unlike many other new bikes, there is no rubber or plastic cover for this
area. At the top of the handlebar uprights are clamps holding the bar ends,
which are angled, providing for up-and-down adjustment. The range of
adjustment is limited by a pin in the handlebar end, but it’s sufficient to
keep most riders content with the riding position. While the handlebar assembly
of the Vision is simpler and more adjustable than most, it still doesn't offer
the easy change in handlebar shapes of ordinary tubular handlebars, a feature
many riders like.
Positioned
in any of the three possible handlebar positions, the bars would be considered
normal. All the other positions and signals from the Vision indicates it falls
within the vast middle ground of sporting street bikes, looking ready for track
use but also being comfortable enough for extended travel.
Riding
the Vision demonstrates how wide that middle ground can be. Around town the
Vision’s behavior is exemplary. It starts well cold or hot and can be ridden
away immediately without hesitation, stalling, surging or dying. Only if the
throttle is opened fully at low engine speed can the engine be made to cough or
sputter, but without trying to provoke a difficulty none occurs. The engine
is surprisingly torquey. It pulls strongly from idle,
with noticeable flywheel effect for getting under way, but no hesitation to rev
at any engine speed. Revving the engine with the bike parked produces a
medium-loud gear whine from all those straight-cut gears. There's also a
pleasantly subdued exhaust note, but there is no clatter or mechanical noises
besides the whir of gears. That gear noise disappears on the road as the exhaust
noise becomes the only sound from the motorcycle that a rider can hear. It's a
pleasant sound, a bit too muffled to please some cars, but a healthy and
sporting note.
Hold
the throttle open a little longer between shifts and the engine just keeps on
pulling, harder and harder, with no flat spots anywhere. Peak power is produced
At
9500 rpm and there is a slight drop in power beyond this, as the tach climbs to the 10.000 rpm redline, but the engine is
happy to keep spinning until the needle is well past the redline. This isn’t a
two-stage kind of power, but there is enough power at all engine speeds so it
can be ridden gently or thrashed on a track and feel like a high performance
machine all the time.
Controls
on the Vision are particularly light and convenient. The butterfly-throttle
carburetors need only light return springs, so the throttle is easy to turn
and smooth. The clutch pull is similarly light, engagement is positive and it
releases fully, with none of the slight clutch drag common to some Yamahas.
Excellent
engine smoothness makes the Vision pleasant on the highway. The counter
balancer cancels the imbalance of the crank and manages to work effectively at
every engine speed. What it doesn't cancel is the pulse of the engine that
results from the power pulses. Being a Twin, there are half as many impulses as
a Four would have at the name engine speed and it is this reduced frequency of
impulse that eliminates the buzz that occurs in most high revving Fours. This
smooth running engine doesn't have as noticeable a smooth spot as many fours,
which makes judging engine speed almost impossible without the tach. As nice as the smooth-running engine is, some riders
lamented the lack of Twin feel in the Vision. Not having the usual V-Twin
stagger is one reason why the Vision was thought of as a mid-size bike, or a sport bike than it was thought of as a Twin.
Handling
is as strong as the engine performance. For the past several years Japanese
sport bikes have progressed from questionable to competent in handling as
frames have been strengthened and suspension has become more controlled. The
Vision's contemporaries are noteworthy for their absence of handling flaws,
most of them possessing good cornering clearance and an admirable resistance
to wobbles under most circumstances. The Vision goes these bikes one better.
It isn't just that it has nothing wrong, but that it offers positive
characteristics that help a rider.
Instead
of compensating for the machine's flaws, the Vision rider gets to apply the
machine's strengths, and nowhere is this more evident than at a racetrack. Taking
off from a start the Vision is a match for the best in class, though it's not
going to beat those fast red bikes to the first corner. With its single front
disc brake, the Vision doesn't look like it could match the braking power of
the double front disc equipped bikes. Yet on the track riders would begin laps
braking at normal points and find themselves going too slowly through turns,
with lots of cornering clearance left and lots of room for more speed. With a
few laps of practice riders could enter turns much deeper than they could on
last year's KawasakiGPz550, for instance. It isn’t that the brakes of the
Yamaha are stronger than the double discs, but that the single disc of the
Vision is strong enough and controllable enough not to be a hindrance and the
handling of the Vision is markedly superior to competing bikes. Most of the
Vision’s race track advantages comes from its ability
to change direction quickly. That’s what the Vision is designed to do and it
does it well.
This
ability to change direction easily and controllably has not cost the Vision any
stability. It is provided by the compact engine, mounted low in the frame and
reducing the roll inertia of the bike. The Vision does have a steep 26,3 degree steering head angle, but the 57 in. wheelbase and
4.5 in of trail aren’t extreme for this size bike, both figures being a bit
longer than normal. The Vision’s 462 lbs of weight is about average, a good 38
lb. Heavier than the Seca 550, but a couple of pounds
lighter than the Kawasaki GPz550.
Combining
with the ease of steering is precision and excellent cornering clearance. This
is particularly valuable in variable radius corners, where slight corrections
at the handlebars make instant changes in the bike’s attitude, keeping the
Vision on the proper line. Like most Japanese bikes, the Vision is designed to
touch down at the pegs first when leaned over far. Unlike anything else in its
class, the Vision must be leaned over far more before those pegs scrape. Pipes
and pedals and stands are well tucked up out of the way and pose no problem in
cornering.
The
stock Dunlop tires work well on this bike, not sliding even at extreme angles
on average pavement. The Vision’s drive shaft was a benign as the tires on the
track, not causing any difficulty or even being noticeable.
Only
one part of the test track caused any difficulty for the Vision, that being the
fast, bumpy turn eight at Willow Springs. The Vision could be ridden flat out
in 5th trough eight, but it produced a slight pogo sensation with a
lighter rider on board. It didn’t get worse after 100 m of racetrack and it
wasn’t difficult to deal with, but some more suspension tuning could probably
eliminate this.
Remember
that the Vision doesn’t have the fashionable multi-adjustable suspension that
many larger bikes have. It has a variable rate coil spring and a damper in the
back and forks with no more adjustment than what a change of fork oil can
provide. The result is a sporting suspension that works well on the track with
a variety of rider sizes on board. The shortcomings of this suspension are more
apparent off the track where the ride can be a bit firmer than some of the
competition for one rider and too soft for a rider with passenger. It doesn’t
take a very large passenger to make the back end bottom over dips and bumps.
The bike isn’t incapable of carrying a passenger, but it also isn’t as adept at
load carrying as a larger bike is.
At
the other extreme, the Vision can be bouncy on concrete freeways where it
hobby-horses over expansion joints. It could be improved in several areas by a
progressive rate suspension or more adjustment, but either of these would cost
more money and that is an important consideration on a bike competing against
as many other models as this one.
Compensating
for a little roughness in the suspension is a seat that is better padded and
better shaped than the seats on most bikes this size. It is relatively flat,
with no grab strap over it, making it easy for the rider to move around on the
saddle during long trips. The excellent seat and the smooth motor make the
Vision an excellent touring bike even though it doesn’t have the pillow-like
suspension of a GL500 Honda, for instance. With its 4,5
gal. Gas tank the Vision can easily go 200 miles between fillips. A rider
doesn’t have a difficult time riding that far on the Vision, either. The broad,
flat top of the tank makes a good tank bag surface, though the odd handlebars
interfere with mounting some kinds of fairings.
How
the Vision stacks up against its competition will be concluded after the new
single shock GPz550 is tested. Right now it is equal to the fastest 550s for
speed and acceleration, superior to anything in its class for handling, and all
the time it manages to be as easy to ride and as comfortable as any mid-size
machine.
Well
done, Yamaha. You’ve managed to make a bike that’s not just different, but
different for good reasons.
RIDERS OF VISION NEWSLETTER
#8
JUNE, 1987
I debated a long time before delaying production of the
newsletter until after I came back from Loudon. Normally, a small rag like this
one is better off coming out in a timely fashion, but because of the
possibility of passing on some bits about Visions in racing, and because of
the great loyalty shown by you people to Riders of Vision in the past, I thought
I could get away with it. I thank you for your patience.
Let's see......... describe Loudon weekend in two or three
paragraphs making it appeal to you who are of rowdy ilk, and also making it
palatable for those of us a little more reserved. Loudon weekend contradicted
many of my original perceptions of what motorcycle racing was really like. There
are many short races throughout the weekend separated
by long breaks while the track crew sets up for the next race. I got to read my program through cover to
cover 27 times. The rowdiest people in the crowd were also the ones with the $2800
camcorders and the $750 Nikon cameras.
They were also drinking expensive imported beer. The
Harley riders were quiet and composed, no exceptions.
I actually bought a reasonably priced genuinely tasty hamburger. The people who
sell burgers at ball packs could learn something from the bike crowd. The
locals, not the ones who made a lot of money but the ones who merely live close
to the track, lined both sides of the road leading away from the track waving
and cheering as we left. Some had even erected banners thanking us for coming,
wishing us a safe trip home, and telling us to be sure to come back next year.
They made me feel like a hero as we all drove slowly away.
I saw no Visions racing in any class. There were several
heavily modified Viragos in the Pro Twins class, none were competitive. I did see
other Visions on the road and several racers were using clapped out Visions for
pit bikes.
I never did get to talk to any of the Vision racers
because they were either not close to their bikes, or going down the road in
the opposite direction. Jimmy Adamo is still riding a
Cagiva. He was leading the Pro Twins class until he
developed what sounded like an ignition problem near the end of the race. Maybe
he should have been on the Vision.
I won’t bore you with the results of the finals; if you
are interested in racing you will already know who won and in which race. Suffice
to say that Kevin Schwantz was every bit as awesome
as the magazine you just got says that he was. His Suzuki was working perfectly
all of the time, and when coupled with this mans talented riding, was unbeatable
that sunday. There is no way
that I can describe how it looked to see a motorcycle work that well and go
THAT fast. You'd have to see it for yourself, something I recommend you look
into doing if you have never done it before. I had a REAL GOOD TIME.
OLD BUSINESS
George and 1 have finally managed to put an offer for
shirts together for Riders of Vision, and you people have now sent in enough
requests for them that he is starting production. George will be handling the
entire thing from taking the orders to producing and sending the shirts out to
you. The shirts will be 100% cotton, long sleeved, heavyweight "T"
type in a light blue with a two color graphic similar to the photo of the
Vision found on the original sales brochure and saying "RIDERS OF
VISION" next to it.
The cost of the shirts will be $12.75 plus $2.00 for
shipping and handling. George wilt accept a personal
check or money order from club members and asks that you allow six weeks for delivery
since he will be doing them in batches. He got no suggestions from other
members, but the graphic that he put together is a handsome one and the shirts
are of the finest quality. You need to send your orders to
Octograph RoV T
6447 Glade
Ave.
Cincinnati, Ohio 45230
And send him a note of greeting if you get the chance. He
is a very avid member of the club.
As a follow up to Ted Elzinga's
suggestions for reducing print size, I got several letters from members asking
that I keep the print size as is, so I did. I got even more letters supporting
the graphic Ted sent in as our letterhead. So I'm going to keep that as well. Starting
with our next newsletter, this graphic will start off all official out-going
mail.
NEW BUSINESS
As soon as I can get our ad removed from the pages of Ríder magazine (the one with the wrong address), I am going
to start an ad campaign to several of the bigger magazines. The club is a few
dollars ahead and I think this would be a good place to spend. If we can get
more members into the club, we may be able to start having some local events in
certain areas.
Several members have asked that 1 make up a list of
members and their addresses and put it into the newsletter. At the time I said
I would, but after figuring out how many pages it would take (about 9), I
thought maybe I'd better not.
The cost of such a newsletter to print up would be more
than double the cost of a regular issue. Not only that but
the membership changes some throughout the year so the list would be
obsolete quickly. I would like to make this information available to members
somehow. Does anyone have any ideas for doing this? Should I offer this info in
a special deal like the Biehle carb
fix paper? Let me know what you think. Maybe reducing's
the way to go in this instance.
CORRESPCNDENCE
Phil Winkle, a new member, wrote in to ask a couple of
questions of the membership. "I wish to lower the seat height an inch or
two by installing a Corbin style seat. Has anyone done this? Corbin will do the
work provided 1 send them a seat pan. However, I want
to keep the stock seat as well. Does anyone have a seat pan for sale? Also when
I remove my hands from the bars at about 30 mph, the front wheel wobbles from
side to side. I know this is not uncommon with modern bikes, but does anyone
have a cure for this?"

Charles Eichhorn, also a new
member, wrote in with a couple of problems and a critique of the Fairing Screen
Gustafsson. He says he got "Good quick service. Fit
well enough, but clarity of material is poor - bubbles, etc." The problems
are ".... exhaust leaks at the heads, even after new gaskets, and
unbelievably hard starting when cold (maybe 50 degrees). Running is fine - no hesitation, etc. No choke adjustment
seems right. Best bet is to over choke and pump throttle constantly while
cranking for about a minute or more. Accelerator pump gives it the right amount
of gas. Worst I've ever seen on any bike, and that's saying something." He
said the dealers didn't help.

Dan Dees wrote in from my home state of Virginia to let us in on a couple of items.
The first is that I was a little out of place a few issues back when I said that
the ultra-sonic warning devices advertised in Dresser Jacks were of dubious
worth. Dan is sold on them and is willing to sell you one for $27.00 each plus
postage. He didn't mention what postage was for this item, but if you sent him
an extra 2 bucks, that should cover it. He went on to say that REV-PACK of New Cuyana, CA makes quality bags and packs for reasonable
prices. He says they look great on Visions, too. Daniel Dees, 2259 Westover Ave. SW Roanoke, VA 24015
Dave Kimmey wrote in with a
place that sells used Vision parts, "......a motorcycle graveyard here in
Miami called Discount Motorcycle

Dave writes for a small local paper in his area and he sent
me in one of his articles. It appears in the last bits section.
Joe Minuni of Gilbertsville, PA
wrote in with another successful story of curing rust with KREEM. He also wanted to know how many members we
had. At last count we had very nearly 200; in fact we have taken enough new
members in that we must be over that number by now. I plan on improving those
numbers even more as I discussed before.
Vicki Botz wrote in from Seattle,
Wa with a request that I publish information on dues,
etc. on a regular basis so that when she tells other Vision riders of the club,
she can get the details right. Let me take this time to tell you all that with
each request for information from possible members, I send out a free current
newsletter and a sheet of guidelines that run the club. All of the information
needed is on that sheet, and you may take a look at a copy in Last Bits.
This will inform you and let you know that all you really
need to give perspective members is our address and some of the benefits of
being a member. Thanks Vicki.
Eric Johnston from Paradise (actually Lemon Grove, CA)
wrote in with this. "My..... complaint is
relatively low mileage. After topping off the tank, I can go exactly 120 miles
before having to hit reserve. How is everyone else's mpg?" Eric has an '82

Larry (no last name nor return
address given) from NJ wrote in with several good tips and recommendations. "Advise
against Conti Super Twins (TK22/44). BAD performance on this
bike. I even got a refund from
Continental." And "After minor crack-up which disintegrated factory
1/4 fairing, replaced with Tracy 'Road Warrior.' Excellent fit and function -
adapts perfectly to the Vision. Tip: Do not buy 'cast bar adapter kit.' Superfluous. Much
cleaner fit by bolting standard brackets to existing bar holes after removing
standard plastic cable guides. Route cables over top for set – up that's better
than the factory fairing."
Finally “anybody with synthetic oil
experience - good or bad?” Joe Kamplin
of San Francisco
wrote in with a question that some of you may be able to answer. "Have you
heard of anyone who's installed an oil cooler on their '83 Vision,
and if so, what brand, where on the bike it was installed, and results?” Joe's
address is: Joe Kamplin 981 Rhode Island, San Francisco, CA
99107
Just found a note from Owen Floyd of Líttle Rock, AR
about synthetic oil. "I have tried Golden Spectro
20w/50, and it does shift a little easier, especially finding neutral, and
quieter. I had been using Castrol 20w/50." This
helps to answer Larry's question.
I'm getting more and more letters from members who ended
up being less than totally satisfied with the Spec II exhaust. Billy Brocks
from Stuarts Draft, VA is no exception. He writes "I tried the Spec II
exhaust and found that I lost some top end. I visited Spec II in Burbank, CA
and they admitted to me that they did not do enough testing on the exhaust
system. They suggested welding a 'connecting' or 'equalizing' pipe between the
two pipes for better breathing at high rpm. Needless to say, the better
solution is to simply re-install the stock exhaust."
Corinne Walters from San
Diego, CA write in with
a warning. "My boyfriend replaced my starter the other day and learned the
hard way that the starter is below the oil level in the crankcase..... we didn't intend to change my oil right then. This isn't
mentioned in the Vision service manual. Could you pass this one on so that
others will be ready with something to catch the oil......
(after paying about $225.00 for a starter, you don't want to spend money on oil
too if you don't have to?"
Leif Hendricksen of Plainsfield,
IL sent us a suggestion that may
be of help to some. "A quick and easy fix for the chronic leaking of the O
rings at the lower end of the coolant pipes is as follows......when replacing
the O rings, put two snugly fitting garden hose washers on each of the coolant
pipes before fitting the 0 rings. When the pipes are reinstalled, slide the hose
washers to the end of the pipes covering the recesses that receive the ends of
the pipes. This will keep grit out and insure leak free operation."
Peter Spirka writes in with a
question. "Does anyone know about engine
transplants into superior chassis (that is within reasonable financial
parameters, not Bimota or Harris), or fabrication of
better frames from scratch?" If you can help Peter, write him at this

Robert Burget wrote in from Hayward, CA
with some helpful news about seats. "Young's Custon
Seats in Sacramento
did a good job on my seat. They can do virtually anything you want, and in one
day if you arrange ahead of time." Robert also sent in some information
about the 750cc racing Vision of a year ago. It just so happens
that Tom McKaskle of Cape Girardeau, MO
sent me a copy of the article from Hot Bike covering this machine in detail. I
have included this article in this newsletter for your enjoyment.
And lastly, Vernon Cooke, a long standing member, wrote in
with a history of his bike and a couple of recommendations. "I do not recommend
Progressive fork springs for the Vision. The diameter (OD) is .060"
smaller than the stock springs. This difference creates a terrible fork noise
upon compression. The manufacturer has no recommendations and will not
manufacture the proper size since they begin with a standard size OD
spring." Vernon

expertise with anyone interested. His address is: Vernon P. Cooke 1257 Borden Rd. Escondido,

He also purchased from Dennis Kirk a pair of Krauser Saddle Bags for $200.00, mounts included. He goes
on to say that ". .....These do not detract at all from the bikes sporty
look and add a great deal of storage space for touring. The bags look very
similar to the smaller BMW bags also made by Krauser.
Krauser also makes a set of soft zippered inner bags
for the Starlett. I highly recommend them over soft
luggage for appearance and security"

- Just before I went to Loudon, I purchased from Chaparral
a set of Hagman premier saddle bags. The price $150.00. The bags have a polypropylene liner in each
that makes them hold their shape when empty. They come with zippered liners for
your stuff inside and liners to hold back rain on the outside, both of which
fit well. The bags look good on the bike, and hold a fair amount of stuff,
certainly enough stuff to go for 4 or 5 days. They are quality pieces, and
should last me a long time. I thought some of you may want to hear what I
thought of this item.
-several of you members have told us stories about heat
under the gas tank boiling the gas out of your tank. Please welcome me into the fold of the initiated. The trip down to
Loudon took place for me on Friday, an honest 85 degree day. The first place I
stopped for gas at 157 miles, I pulled right up and filled it to the brim with
high-test. I turned around to replace the pump nozzle and when I turned back,
gas was boiling out all over the front of the tank. It took several seconds for
the process to stop. In the mean time everyone standing nearby ran away very
quickly. The owner of the station told me to run - everyone told me to run for
my life. I knew that the situation was not dangerous as long as I waited a few
minutes for the gas to evaporate before I started it, so I was busy swearing a
blue streak because my good wax job was shot to hell. In any event, you may
wish to wait a few minutes before filling your tank if you have just driven a
long distance in warm weather. I know I will from now on.
- I guess that's about it for this round. Enjoy the two
articles here next, and have a real good time riding this summer. We recently
lost a member because some old person flattened him and his Vision. He will be
OK someday. The vision is twisted scrap. RIDE SAFE! watch
out for people not watching out for you, OK? Depend on your own vision.

Velocity Vision, a Yamaha With A
Future in the Fast Lane, by Paul Garson from Hot Bike, November 1985
Eddie Willbanks leans toward the unusual.
He makes his meat and potatoes designing and building exhaust systems for
ultra-light aircraft, but he’s also campaigning an AA
Fuel drag car, and built drag race bikes, besides that he has some pretty good
friends….. that’s the way they grow’em
in Memphis, Tennessee.
Now a while back Eddie looked at the Yamaha 550 Vision, a vee-twin water-cooled bike that just didn’t make it to the
Top Ten in sales. He realized here was a “sleeper”, a bike that had real
potential, and set his inspiration down on the drawing board, then wrenched it
into reality in the form of
this featured roadracer ridden by
Stuart Cooper. Eddie’s inspirations included a very unusual rear suspension modification
plus bumping the 550 to 750 ccs.
When we interviewed him about his project the first thing
Eddie did was mention the sponsors that helped make his unusual Vision Quest
possible.
First off, there was Ray Godman
of Godman Automotive who supplied all the hoses,
brake linings and oil cooler (Ray, says Eddie, is an old … well, a veteran drag
racer who owned the Tennessee “Bowl Weovil” dragster.
Kal-Gard supplied the lubricants – engine, fork,
chain products which helped spell the difference especially when it came down
to pesky roller bearing problems. It was Clovite Bearings
who came up with their #77 Rod Bearings which eliminated those problems altogether,
supplying excellent technical assistance from their laboratory in Cleveland, Ohio.
(Clevite is the same bearing company that has been
working with Scott Braden and Pancho Carter on the
Buick V-six they run at lndianapolis. The company is
now interested in helping smaller teams on a local and regional level, by the
way.) Last, but not least on the sponsor's list, Eddie's exhaust is courtesy of
the people at SuperTrapp.
As for the components of the Vision racer, Eddie chose Brembo brakes, four piston QD (quick
detach) set-up on the front and a single piston on the rear, purchased from Slater
Bros (importers of Laverdas). From England came the trick Astralite
wheels sold here by Grizzly Engineering in Sacramento.
Rubber is from Dunlop (a KR 133 up-front), the tires
supplied through Stanley Chan of Deus Ex Mechina
(Brooklyn, NY) who also handles the new Ceriani road
race forks seen on the bike.
While Godman, Kal-Gard, Klevite and SuperTrapp are the official sponsors, Eddie noted that
several of his friends contributed cold cash to the project, personal friends
of Eddie and Stuart who were interested enough to see the project happen that
they donated cash; Ron Butcher of Dyersburb, TN, Al Briuda, and Don Engebretson. Don
and Al are serious racing fans who happen to pilot aircraft for Federal Express
(Ron also runs a 750 at the Bonneville Salt Flats).
Another friend, Jimmy Dobbs, contributed to the fund while
Eddie and Stuart received help for their trip to the last Daytona Speed Week
from a group of Memphis
café bike riders called the Mid-South Sport Riders Club. Memphis seems a place where generosity is not
in short supply.
Design of the chassis and frame was handled by Eddie with
Ron Wigimon (?) (who also
built Leo Goff’s champ Kawa-Norton Drag bike). Constructed
of 4130 chromemoly, it incorporates some ideas from Bimota while the rear suspension is Eddie’s own design. It
is an air over oil monoshock featuring variable
damping and spring rate accomplished by varying the air pressure.
The engine features a custom built billet crankshaft, Carillo connecting rods, and some special TRW piston
forging. Bored and stroked, the engine is now 750 cc running the stock tranny and clutch with modified oil pump for increased
flow.
In the weights and measurements department the Vision,
with oil, but no gas, weighs in at 330 lbs. Now the Dyno
Don’t Lie, and the statistics are impressive …. 87 HP at the rear wheel at 10,000 RPM with 78 ft/lbs of torque at
7500 RPM.
A 48 mm Weber downdraft carburetor supplies the fuel
supplied by Redlines Inc. (Torrance,
CA) [http://www.redlineweber.com/t_c.html]
who also helped with technical assistance in the form of a toll-free phone by
which Eddie gave them his dyno results and they
figured the carb adjustments needed.
Cylinder, cam shafts and intake manifold are contributed
by Ken Clark of Yamaha, while the special project heads were “one-offs”.
Currently, new cam shafts are being prepared by MegaCycle as the present cams are almost stock, and very
mild.
Eddie built up the fuel tank over a foam core, after covering
it with fiberglass, a process similar to the construction of ultra-light aircraft.
The seat and tail section were fabricated from aluminum.
Oddly enough, Eddie found that a Yamaha motocross chain
works out best so far. A rod bearing failure cut short the Vision's first race
effort at Daytona (before Clevite supplied a better
bearing). Soon after, at St. Louis Internationals Raceway, during a club
event, the Vision took everything.
Then, at Sears
Point, engine problems
sidelined the bike. At Laguna Seca, the Vision qualified
23rd in the Formula One Natíonals and finished 18th.
In the Battle
of the Twins, Stuart stalled the engine on the starting line, starting off a
full 15 seconds late. No problem , . . in seven laps he caught up to Gene Church (took second
place), but in an attempt to get around, crossed onto the white line and
slipped down, out of the action.
Future plans include contesting the entire BOTT series, going
for a win in the class championship for the next season. After a year of development
and dialing-in, the Vision looks ready for BOTT Grand Prix competition (1000 ccs or less. two cylinder four stroke).
Eddie was involved in auto drag racing up until 1974
running a AA fuel dragster with a Chrysler late model
hemi-engine. After that he got involved with motorcycle racing because of the
economics involved in auto racing. Over the years, he's been involved with
several Camel Pro riders, and built two Ducatí 750
fiat track racers. The Vision is his first effort in road racing. At his shop,
Eddie focuses on "custom fabrications", including drag rating chassis
and transmission modifications .. . the
Vision was built top to bottom entirely in his shop. As mentioned, his main
source of income is from custom built exhaust systems on homebuilt aircraft.
Rider Smart Cooper is executive vice-president of the Dyersburg
Cycle Corral, a Yamaha franchise operated by Stuart and his father. In 1984
Stuart rode a production framed Vision in the BOTT GP class to a fifth in Daytona
at the Pro Am, fifth at Laguna Seca, and sixth at
Pocono on a modified production framed Vision. He was also in the AMA Championship
Cup Series in die Super Twins (0-750cc) Class, and took second to Adamo’s first. In the 750 on up, he was again second, again
to Adamo. He was national points leader in three
classes in the Cup Series, the AMA CC's top contingency money - winner as well.
In 1983 he rode the WERA Endurance Championship, on Team Good Times, taking
first in middle weight production and third overall in the 24 Hours of Nelson
Ledges. In another big endurance race, Texas World, the team took first in
their class, third overall.
Not only is Stuart a good rider, he helped put his
dealership in the top 50 nationally with total units sold. In addition to
riding the Vision, Stuart also rode Cagivas for Reno
Leone, finishing third in the BOTT at the Pocono. He is also riding for Team Cagiva on their Fornula One bike,
the square four 500cc machine.
Yamaha Engineering Group is now supplying Eddie with
assistance under the guidance of Hiroshi "Hugh' Yamamoto, general manager
of the engineering division of motorcycle operatíons,
the engíneer directly responsible for the Vision and
the FZ750. A great future seems assured for the Vision of Eddie Willbanks and Stuart Cooper.

THE INSIDE LINE, by Dave Kimmey
When it comes to motorcycle activities are you a real man
or a wimps? You say you're not sure, OK -- take a couple minutes. check out the following guidelines and see how you stack-up.
When it looks like rain, real men ride anyway; wimps stay
home. Real men repair their own bikes; wimps go to the dealer. Real men haggle
for weeks to get a price down; wimps pay list. Real men never lock their bikes;
wimps use several chains then return to find the bike stolen. Real men ride up
front near Sinclair on the Saturday night ride; wimps ride in back. Real men kick
start their thumpers; wimps prefer electric starting motorcycles. Real men ask
for a beer; wimps ask for diet Tab. Real men ride their bikes to Daytona; wimps
take their bikes up in a truck. Real men need a new rear tire monthly; wimps
get 3 years on a tire.
Real men ride dirty fast bikes; wimps ride spotless slow
machines. Real men are happy with a hot dog; wimps want a salad. Real men wear
leather: wimps go for Italian silk. When the light ahead
signals caution. real men gas it; wimps hit the
brakes. Real men hate helmets; wimps love them. Real men pull stock mufflers
off; wimps leave them an and, if necessary, replace
them with new ones. Speeding tickets a problem? Real men get a warning, wimps
go to jail.
The really neat babes seem to gravitate to real men; wimps
end up with you know what. Real men don’t shave. wimps
shave twice daily and brush their teeth also. Real men park their bikes anywhere;
wimps have to pay. Real men loudly announce they just returned from a 350 mile
afternoon ride: wimps say nothing because they haven’t run their bike in 3
weeks. Real men talk about English bikes like the Triumphs and the BSA Goldstar single: wimps don’t discuss their Honda Rebel
much. Real men smoke nonfiltered Luckies;
wimps ask for Virginia Slims. When selling a bike, real men declare its a piece of (censored) but it runs; wimps are quick to
point out their bike's low mileage. Real men always have money, friends and free
time; wimps are always broke, alone and working. Real men love to discuss the
good old days when they raced the circuit: wimps say nothing because they never
raced.
So that's it, the results are in, by now you should have
the good old (or bad) news. Are you a real man or a wimps?
But don't take all of the preceeding too seriously
because if you're serious and I'm Roebuck, nobody’s minding the store.
