To check cam timing, pull the plug( blow dirt out first), Use a straw or wooden dowell & carefully bring it to TDC, Look at the valve positions. If exhaust is open, its TDC exhaust, spin the engine thru 180 degrees & look again. If valves are still open, something is wrong. Is it possible youve adjusted the valves while it was at TDC exhaust?
If this doesnt get you headed toward the answer, Id very carefully turn the engine over & watch the valves. Compare that to the piston/crank position & see if its okay.
If thats not working, then Id have to pull the head cover & look at the cam timing marks on the cam chain gear. If, w/ piston @ TDC that line isnt horizontal & in line w/ the top of the head,,, sumpin is way wrong.
