Good To Know

Q: Does this kit require machine work on the cylinder? A: Yes, a big bore kit typically needs the cylinder bored and honed to match the 94mm piston, so check with a machine shop before assembly.

Q: Is a fuel or jetting change needed after install? A: Yes, added displacement usually calls for carburetor rejetting to keep air and fuel ratios safe during break-in.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
