Won't crank

I have a 92 Bayou 300 that jumped time and sheared the pin on the cam gear. It also messed up the guide on the cam. I replaced all of that, and have set the timing according to the factory manuals. I have gas, fire and fair commpression, but it won't even try to crank. Any ideas?

Pastorized, as someone who's seen the inside of the cam chain tower on one of those things, I'm "studyin'" your problem, hoping to come up with a useful suggestion.
While your valve timing is right with your piston, if you set the piston at TDC (might verify this by sticking something in the spark plug hole, a lot of ambiguous marks appear, I've noticed, the "T" one being the thing we're after) when the cam sprocket mark lines up with the index mark on the cylinder head. Be wary! Kawasaki used the same cam sprocket for at least two different models; two sets of cam sprocket marks may be present; you can be sure you're using the right one if: Both intake and exhaust valves are totally closed at TDC (when the proper mark on the cam sprocket and the index mark on the cylinder head coincide).
However, I'm wondering about the spark timing--the method (of timing the spark) doesn't occur to me off-hand, and my manuals aren't handy; I don't know if the Kawa fires at the end of the compression stroke only or also at the end of the exhaust stroke--if only at the end of the compression stroke, you could be 360 degrees off on the ignition timing (i.e., the single spark per cycle occurs at the end of the exhaust stroke, instead of the end of the compression stroke).
If you get spark at the end of the compression stroke (you can check this out by feeling for air rushing from the spark plug hole and watching the grounded plug for a spark), then that ain't it!
Maybe this mixup can't happen, in which case the possibility I offer is trivial. Otherwise, I imagine you've checked everything a reasonable shade-tree mechanic would in this case.
Good luck, and; been there, done that (scratched my head over a totally dead quad--had that today with my '89 300; simple but unexpected solution: replaced plug. Old plug wouldn't fire even in warmed-up Y2K Bayou!)
E-mail me if this post appears too unintelligible, and I'll try confusing you further!
