After gettin my warrior back together I have absolutely no compression. I had to get the exhaust bolts on the head removed because they snapped off so I had the head off the quad and since I have put it back on there is no compression. Could this be a valve is stuck or something? What else could it be and how can I fix it if it is just a valve is stuck. Any other suggestions are welcome. Thanx

 

recheck your cam timing and valve adjustment

 

What RacinJason said.

 

Cam timing?? How do i check that???

 

nevermind, soon as I thought about it I knew exactly what your talkin about and guess what, that was the problem, I corrected the timing and it fired right up. Thanks again man

 

when i put back together fourstroke motors i always put a little marvel mystery oil on the valves and a little more in the crank. i also do it every timei go on a big ride i would just put a little in the valves even though they aremnt the problem
