However its different in all bikes also if any motor work was done. Adam 823 - MXNewsfeed Test Pilot. Dec 11 2008.

The intake valves on a EZGO have the tendency to tighten up to the point it will hold the intake valves open and youll lose compression. Check the valve lash cold and set it at 006 on the intake and exhaust valves. Recheck the compression and if its still low you have internal problems and it may be time for a rebuild.
