My friend wants to redo his Enya 4 cycle .60 size into a .80 by installing new sleeve and piston. Can this be done, and where are the parts for this engine? Thanks Captinjohn P.S. His Enya is about 12+ years old

Hmmmm, why not just buy an .80??? The cost of the cylinder assembly, rocker assembly, valves, valves springs, spring keepers, piston, ring, wrist pin, gasket set and probably something I left out will exceed the cost of finding one these engine's, NIB.

He was thinking the only parts that was different on that model was a different sleeve and piston maybe rod. all other parts may be the same. As far as gaskets it is simple to make your own. I do not know for sure myself. Need to talk to a old Enya pro. Thanks CaptinJohn
