Also the +2 stamped on the head meant it shoulf have a 44.2mm piston.
After slapping it together I had 120 psi compression with engine cold.
Wow that's fantastic I checked mine today and I was getting 85 PSI. I originally thought my clutches were the problem but maybe I have another problem. I know that the cylinder was honed and the Piston is new I'm not sure why the difference in PSI
Also just put the wrist pin in freezer for a half hour, then slide it in through the piston. (Dont bother heating piston at all).
man im looking for this 60cc for ages..hardcore to find...look at my channel check out my high end minibike :D 70cc with welding etc
