I just got my parts in and now i'm putting back my bike together. (i blew it up a few weeks ago) Now i can't get the thing to start. I don't know if its my timing or what. It doesn't have a line on the rotor where you check you timing like the manual says. It has three little ones close together. now i don't know whick one to use. i used all three and i can't get the pig to start. i'm not sure whats wrong. i'm out of idea's so i came here. If any of you can make some sense out of my jibberish, please help me out.

I assume you are getting a spark. Remove the plug, put it in the ignition wire cap and hold it against the head. Do it in a dimly lit garage. Push the kickstarter with your hand. Are you getting a blue spark? Write back and let me know what happened.

yep there's spark.......but i'm pretty sure i found the problem....see I tweaked a valve...bummmer.
I'll tell you the whole story....
Siezed the motor and it twisted the piston about on a 45 degree angle and it must of hit a valve. I got my parts and put it back together but there was no compression stroke. I thought it was the timing opening a valve to early or something but its not that. I took the cams out and slowly pressed on the kick starter and listened. I heard a hiss coming from one of the valves. I don't know how to fix this one so i'm taking it in to the dealership tomorrow. To replace a valve, can i replace one or the whole set????
thanks for responding.....everyone must be out riding or something????????
