I have a Chinese 66cc, after about 6 mos. did a tear down for maintenance, after reassembly pin clip ejected and scared piston before fusing to cylinder wall. Bike berry had diagram but my dial calipers came to different totals. How can I remedy for oem or upgrade?

Welcome Havasu!
Where you get the kit? Only 2 types of pistons that I know of. one has the wrist pin hole higher up the piston than the next.
This may help.

You will have to measure it across the diameter, and height, look at it closely, then find one that is right....I know that sounds stupid, but I have had bike engines with displacements of- 45cc 47cc 48cc 49cc 66cc 67cc and 68cc.
