i was riding my 04 raptor one day and it just died all of a sudden and i could not get it started back. got it home and tore it apart and looked at all the valves and the center compression valve looks like it is stuck down a little bit from the other two. i took the plup out and turned it over to check to see if it had any compression on it and it didnt have any. what is the best way to fix the problem. if anyone can help me out i would really appreciate it. i am trying to sell it and i need to get that fixed first so i dont lose to much money.

 

How did you do the compression check? If the valve appears to be stuck down you may not be in terrible shape unless the piston contacted the valve.. did it make any kind of weird racket when it shut down?

 

i just checked it by putting my thumb over the plug hole and cranking the motor. i didnt hear any racket when it died.
