who did the valve shim adjustment?
are you sure timings on now? how were the intake valves? usually those are the ones that need the most attention. when you pulled the plug was it dry or wet? if dry then your not getting gas with a backfire out the carb i would guess your timing is off and if the timing is off i would guess its not looking good for your valves. i would pull your plug on the mag side put the T in the little notch and pull the valve cover and check your timing marks. i wouldnt try cranking on it until you make sure timing is on 1 tooth will crush a valve into a piston and toast a head.

Ok I'm looking at the timing.and at another thread on here..I have the timing mark to the left of the t lined up,on the notch.my intake or rear cam marks looking at the quad from the right side are at 12 and 9. The exhaust is at 12 and 3.and looks like the lobe is opening the exhaust valves.from what I read on the other timing thread the lobes should be facing outwards and are both came supposed to be at 12 and 9 ?

ok your timing is off. you need to be on the T mark not the line next to the T. then front the right side of the quad(or clutch cover side) intake will be at 9 and 12 and exhaust should be 1 tooth above 9 and one tooth past 12 if the marks are at 9-12 on intake and 12-3 on exhaust your timing is off and prolly have a bent valve now. i am looking for the picture to show how it all lines up as soon as i find it ill post it up for you
