only worthwhile if you are determined to leave the motor
stock. If we altered the squish band, decked the cylinder
and raised the compression on the new motor, it would
actually have been more powerful. But, for the 24-Hour, we

power valve was stuck. The idea of actually starting a

agreed to take it around that first lap of the 24-Hour, he
would never come back alive.
Clearly, we didn’t inspect the bike adequately at the
point of purchase. In fact, we didn’t inspect it at all. It was
what it claimed to be, however, and that was good enough
to make it a different kind of project. Was the combination of the 2000 motor and the 2004 frame as good in real
life as it seemed on paper? There are actually a number
of people who have done the same project, so there’s a
fair amount of information to be gleaned from Internet chat
