Motorcycle Questions? Ask a Mechanic.
you still have cylinder leakage problems. You should be getting a compression reading over 100 psi and up to 135 possibly.
Did you have the cylinder rebored or honed or measured to determine the piston to cylinder clearance? Is the head gasket okay?
Something is keeping the compression low. check compression with the throttle wide open.
Is the piston coming up to the top okay?
Let me know what you can find.
Something seems off with that compression, is the gauge working normally on other engines? The piston should come right to the top
of the cylinder. If you add a few drops of oil in the plug hole the compression should come way up if the rings are leaking.
