Do you have any pics?

Yes, an open valve will cause the condition you described.

I think maybe if you have no idea what you are doing...you shouldn't be working on the head with out a service manual.....start with something easy....like an oil change...or carb cleaning....maybe tire pressure....JK

TIRE PRESSURE     LMAO

[dantheman]

[dantheman]

pics of the bike or of the valves??? lol i have pics of the bike but not of the valves

Take pictures of the engine, and what you've removed so far.


But, a messed up valve would cause the bike to not turn over? my warrior has a dinged up valve, and it still runs like a beast.

[TRX450R_Racer]

If a valve is stuck open ypu will have no compression and it won't start/run.

it sounds to me like you broke the cam chain. if its an overhead cam, turn the cam over and see if the chain is broken.
