Hi guys. I'm in the process of putting a second hand 125cc lifan into one of my pitty's.
The right side crankcase had a crack in it so I took one off one of my old engines (exactly the same motor ) and put it on. Only problem was that once it was on, the motor had no compression.
I took it off and the compression was back. It seems that once I tighten up the bolts, I loose compression.
I can't see anything wrong but assume that the clutch might have something to do with it?
Any ideas or suggestions would be greatly appreciated. Cheers, Paul.
