I wasn't born yet in '66.

I was riding motorcycles when I was 4 or 5, but that was in
1973. If you haven't worked in a motorcycle shop you just
wouldn't understand the irony of most "race bikes."

My current bike is a 1995 Triumph Speed Triple that was
a Speed Triple Challenge race bike. Then it went to a local
Triumph Dealer and "race tuned" to 65 HP for the owners
personal use. (Dynojet dyno tested after I purchased it and
before I fixed it up.) This bike stock is about 87 HP.

With minor tweaks it now puts out 110 hp at the rear wheel.
(Another dyno run.)

Just one example of many that I saw. I truly admire the
professional motorcycle race teams, but despise the B.S.
of the wanna be racers.

It is a shame that most of motorcycle history is not well
documented. I'm sure most of you that "knew how the valve
train worked" were around to witness it in person or see it
in a then current motorcycle magazine. Now some of
the truly odd bikes get written up now and again. (I'm
thinking of the Moto Guzzi V-8 road racer that was a small
displacement motor as well.) Anybody here ever see one of
those in person?

Time for a ride on the Triple, it's 78 degrees and clear
here in Sunny Arizona.

Too bad you can't really see
how the valve train was put together. (Shim over bucket,
shim under bucket or shim on valve stem.)


It's just about the most famous racing motorbike ever made (and most
famous rider). Kids who were my age could draw the engine from memory.
Don't you just _know_ how the valvetrain on this bike worked? Many of my
generation did when they were about 8 years old.

Yet _you_ think "it sounds like a two stroke"
