Good To Know

Q: Are these pistons compatible with stock cylinders? A: They require the cylinders to be bored to .040 over to match, so you will need a machine shop to perform the work before installation.

Q: Do these kits include piston rings? A: Yes, each Namura piston kit typically comes with rings, wrist pin, and circlips for a complete top-end rebuild.

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