I have the same problem, the only way the bike would start is peddling like crazy down a steep hill, engine would start for a second, then turn off...would do this a few times while holding the throttle wide open...eventually would stay on.....now won't start at all...just makes squeaking sound while trying to start....did you find out if CDI problem or magneto?

It actually wasn't a clutch problem, it's weird... I changed a broken metal seal between the head and engine. and the noise stopped.
But now the problem I have is new. I can't get the bike to go, the bicycle tries to start, sounds like it is trying to give it gas when throttle is turned, but it just won't start...
peddling my ass off with it running, having the gas go into it but not starting...
could that be a spark plug or CDI plug problem?
