Im rebuilding a 1975 yamaha GT80 and I keep seeing these pistons for a fair price....normally I would just go oem but the bike needs cables, kill switch, tires and a few other things so trying to keep the $$ down. my 15 year old will be doing "most" of the work and even put up $100!!! shock to me!! After he plays and learns the clutch and powerband my 13 year old girl will be next. anyway I know its not a mini bike but Ill give this a shot...thanks!
