i have a 05 king quad somtimes it will die when you give it the gas to go , also wont start somtime not very often, but its stating to happen more common any idears what to do to fix

 

Is the engine fully warmed up before you "gas to go", or is it still cold?

Don't know if your quad is air or water cooled, but air cooled motors are notoriously cold-blooded.

If this is not the case, the symptoms you are presenting could also be caused by the valves being out of specification (probably insufficient clearance).

It is also possible that it is a combination of both.

 

its warmed up does not do it all time it is liguid cool and fuel injected

 

Check your throttle position sensor, clean your fuel injector, check your engine airbox intake for cracks, and clean air intake butterfly.
