Good To Know

Q: Does this kit include a cylinder? A: No, this top end kit supplies the piston, rings, wrist pin, and gaskets but not the cylinder itself; you reuse or replace the cylinder separately.

Q: Can I install this on a stock bore head? A: This .020 over bore kit requires the cylinder to be bored to 65.5mm and honed before installation; stock bore heads are incompatible without machining.

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