Good To Know
Q: Does this kit fit every JR50? A: It fits JR50 models from 1978 through 2003, but serial number and bore condition should be checked before ordering. Q: What does .020 mean? A: It means the piston is .020 inch oversize, so the cylinder must be bored to match 41.50 mm.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
