July 1997

One
recent week I serviced no fewer than six 1980something
Yamaha Viragos. There must have been a billion of these
things made. So, I will put aside my sporting tendencies to
pay attention to the laid-back crowd. Cruisers are still
motorcycles, right? I have said this
before, but it's worth repeating: when you are considering
any purchase, get the machine to the shop for a pre-purchase
inspection. The fifty bucks it will cost could prevent a
$1,000.00 headache. The old Viragos
are well known in shops for several problems. Probably most
notable is their starter setup. This deal has got to be the
worst design in history. At best the thing sounds like a
coffee can full of marbles. At worst there is even louder
racket and very sporadic engagement. Unfortunately, not much
can be done about the racket. The starter engagement can be
improved with internal shims. Most shops can accomplish this
for around $200.00. Problem number two
is engine noise--specifically ticking from the cylinder
heads. It may sound like it needs a valve adjustment, but
more likely it has seriously worn valve train gear. The
rocker shafts, arms, cams, etc. are prone to premature
failure. This can be expensive to repair, and on an older
bike I suggest you live with it. It could tick for years
before it dies. Carburetion is
next. I don't know why, but nearly every Virago I work on
requires some jetting work to get it to run well. On the 86
and newer and California models the pilot jets are often
fixed and cannot be altered. These jets handle all fuel
metering from 0 to 3000 rpm. A lean condition is very common
and can be very difficult or impossible to correct on these
models. Now, these
problems are no reason to run and hide from what may be your
ideal bike. Out of the six or seven zillion that are on the
road there has to be a big pile of good ones. Just about
every Virago owner I have met loves the bike to pieces in
spite of the marbles in the starter. If you already own one,
good preventive maintenance goes a long way toward keeping
problems away.
The
AMA Super Cycle Classic at Road America in Elkhart Lake, WI
was held on the weekend of June 6-8. I loaded the bike up
and made the trek. If you have never been there, I recommend
you check this place out. The race track has 14 turns and is
located in and about a somewhat hilly area. The geography
and track layout are considerably more interesting than our
own BIR. The bike racing
was great as usual this year with a new and interesting
attraction added--sidecar racing. Ahh, very amusing. Rather
than a solo effort, this is a true team sport. As a sidecar
cannot lean in a turn, sliding or drifting is the way to
handle the corners. Now apparently any
type of sidecar can enter this deal. The rule book I
obtained is pretty vague. I think just about anyone can
enter. The field at Road America ranged from a close to
stock BMW R75 to all out custom chassis powered by Kawasaki
ZX-11 engines and covered with one-piece carbon fiber
bodies. Some of these
things can be deceiving. Approximate vehicle weights seem to
be in the mid 400 pound range--surprisingly light. Maximum
engine size is 1200cc for four-strokes and 900cc for the
two-stroke mosquito killers. A couple machines ran three
cylinder snowmobile plants. In the pits I
talked to Kurt Dillman of Victor, NY who had two bright
green rigs powered by big ZX Kawasaki engines. I inquired
about the horsepower of his newest drifter, no. 59. His
reply: 180+. Wow. I then asked how fast it would go. He
pointed to my ZX-11 and asked me how fast it would go.
Scary...but in a good way. Kurt went on to
win the main event on Sunday. However, an A+ for effort has
to go to the boys on the old BMW Rwhatever. It may have been
slow, but the crowd appeal was huge. Sideways and crossed up
in every turn they held on, didn't crash and finished the
race. All the while getting major cheers at every
turn. If all this sounds
like your kind of deal, one of the racers from California
builds and sells a very nice start-up chassis. The complete
rig sells for 8,500 bucks. All you need is a paint job, an
engine and someone to be your monkey. I have all the info on
hand so drop me a line if you are interested. Did I mention
the spare ZX engine I have? -Doc M.M.M.
To keep all three wheels on the pavement the driver needs a
little help. Here is the team part. The sidecar passenger
(A.K.A. 'monkey') provides moveable ballast to keep the
bugger from flipping over. Quite a busy job
indeed.
