August 1997

Recently
the need for a used Yamaha part came up. As all roads
eventually head to Sport Wheels, a massive motorcycle
scrap-yard in Jordan, MN, so did I. While one of the
mechanics removed my part from some wreck, I decided to mill
about and look for a blast from my past. After some
searching, I caught a glimpse of something familiar. I
climbed over a pile of bikes to get a better look and, sure
enough, there it was, my first hot-rod motorcycle--not just
another of the same model, but the actual beast. Back in the late
eighties I bought this old 1979 Yamaha XS1100 for around
$200.00. It was an old hippie beater with high bars, a king
and queen seat and over 89,000 miles on the odometer. No
kidding, and no second gear. What a beauty. I rode it for a
year and then had a brilliant idea--I must rebuild it. Pure
dementia. I got carried away
with that project, as usual. My stock rebuild became a
hot-rod ordeal. I had the head fully ported and fitted with
custom ground cams, got a Wiseco 1200 big bore kit, rebuilt
the transmission with new gears and custom back-cut each
gear for better engagement to handle the extra
power. The rest of the
bike was completely disassembled and sand-blasted, including
the chrome and aluminum, then painted. I located a standard
seat, got some sporty low handle-bars and put the whole
works back together. The old XS1100 now made 150
horsepower. Then the problems
started. The shaft drive made the gear ratios less than
ideal for wicked acceleration. Clutches became a major
problem. The best clutches available for this machine would
last maybe five or six full-throttle runs. I went through
about five clutches. The next ordeal
was transmission failure. Yamaha did not design the bike to
deal with big power so it started eating gears. On the third
transmission something went completely awry and some gears
self-destructed catastrophically. A bent transmission shaft,
broken gears and warped engine cases were the
result. Game over...all
roads lead to Sport Wheels. Now, years later,
I am staring at my old bike. It is missing many parts, has a
different front wheel and ape-hangar handle-bars again.
Lesson learned. Life goes on. I picked up my
part from the mechanic, paid for it and headed back to the
shop. By coincidence, the part I left with was a middle gear
unit for a Yamaha XS1100. Creepy?
Back
in the sixties and early seventies we had muscle cars. In
the early eighties we had muscle bikes. These were the years
of the big horsepower standards with 1100cc four-cylinder
engines. Suzuki and Kawasaki basically owned the
show. The most popular
and respected machine of this era was probably the Suzuki
GS1100E. Built in one form or another from 1980 until late
1985, it remains one very sought after bike. Almost none of
these machines ever makes it to the scrap-yard. Virtually
all of them end up at the drag strip. It is without
question the most popular engine for drag racing and is
probably the strongest motor ever designed for a motorcycle.
It is very over-engineered. With a full roller bearing
crankshaft and a four-valve cylinder head 200-250 horsepower
can easily be achieved on gasoline and carburetors. No turbo
or nitrous-oxide needed, thank you very much. A friend of mine
recently purchased a 1983 model in rare form--totally stock.
He bought it from the original owner with 58,000 miles or so
and still in fine shape. Well, of course I
wanted to ride it. I borrowed the machine for a couple of
days and enjoyed a piece of cycle history. Although quite
big, the GS is a great commuter bike. It is a very comfy
motorcycle with great bar location, nice manners and enough
gauges and idiot lights to make anyone happy. The big
air-cooled engine is equally happy on the highway and so is
the rider. I could easily ride one across the country.
Performance-wise, even stock it goes like hell. Five gears
and tons of torque mean not much shifting is required around
town. Getting a hold of
one of these in any shape can be quite a hunt. It seems that
everyone would like one for their own collection and the
drag race boys are always on the look-out. If one shows up
in the want ads you'd better be the first person there. Be
prepared to pay a premium. They do not come cheap. A nice
example of an '80-'83 1100 can bring $2,000+ and a nice '84
or newer 1150 will easily go $3,000-$4,000. Even a rat-pile
junker is worth close to a grand. As I write I am on
vacation in northern Minnesota so see you next month -- I
gotta go canoeing. Doc M.M.M.
