It sounds like the rings are not in properly and have caught on one of the ports. The cam marks should be lined up with the Exhaust and Intake, or straight across the top of the motor, when the cam chain is tight and your piston is at top dead center. I think there is an "E" and "I" for exhaust and intake on the cams gears. You may be able to roll the motor backward to "unstick" the piston, but chances are those new rings will be ruined.

4 strokes don't have ports.......
your motor has to be at TDC on the flywheel before you line up anything on the cams, line up the cams as stated above - I to the right E on the left (standing on the left of the bike looking at the cam gears) for both cams, the outside dots need to be level with the machined surface of top of the head, verify this is still correct after installing and activating the chain tensioner.
Just read your post - so you are saying you want ot spend even more money by buying a pumpkin and spending ALL your time fixing, not riding.......

Sounds like you've installed the cams incorrectly and in kicking it over, run the piston into the valves. No way to fix this other than pulling the cams and dong a leakdown on the motor to make sure you haven't bent the valves (which if you kicked hard you've definitley done).

good luck.

unfortunatly i think i agree with John on this...

if your cams were out of phase... you have bent your valve's more than likley

hope not..
