Bike ran fine about two months ago when parked. Only has about 15 hours run time on it. It just cranks and cranks never catching or getting any run attempts. I pulled the spark plug out and grounded it. I have strong spark. I sprayed some starting fluid into the plug hole and a little into the intake. Still won't even briefly run. I put a compression tester on it with the throttle wide open I only get to about 30psi. I know the auto decompression will affect this, but not sure it should be that low. What I believe is the TPS on the left side of throttle body appears to be where the factory paint marks were initially.
I'm stumped here guys. Has anyone had one of these jump timing while trying to start? I can't think of what else would cause a no start when you have spark and manually insert a fuel. My next thought is to pull the valve cover and check timing alignment. Would rather not if I should try other things first.
Greatly appreciate any feedback!
