hey guys i am new here and new to the atv world i found a 89 bayou 300 for next to nothing it ran but not well i had to change a head gasket i lucked out and got it re timed but i didnt have the timing sprocket nut tight enough and it jumped time now i have no compression i cant figure out how to set the time any help would be great

 

remove valve covers, turn engine over, see if the cam is turning,if so adjust your valves

 

If it's an interference engine, your done. You wacked the valves. I don't know if it is or not? If it is, new valves are in your future.

 

thaks alot guys this may sound stupid but what is an interference engine

 

An interference engine, in simple terms, is an engine that if you loose the timing on the engine (whether you break the chain, belt or whatever, loose the timing of the engine) the piston will hit the valves. There won't be enough clearance between the valves and the piston.
Makes for a BIG fire ball when this happens at high RPM!!! Even bumping the engine over will bend a valve on an interference engine with no timing. I don't know if this is the case or not with your engine. Usually not on a low compression engine like "most" quads engines have.
Let us know what you find out.

 

thanks alot doctorturbo ill let you know
