Good To Know

Q: Can I install this piston kit without boring the cylinder? A: This is a standard 78.00 mm kit, so it fits cylinders that are still within factory bore tolerance. Measure your cylinder for wear or taper before ordering.

Q: What else should I replace during a top end rebuild? A: Rings, wrist pin, bearing, and gaskets are commonly replaced alongside the piston. Check the cylinder plating and clearance before assembly.

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