Good To Know

Q: What does .060 over bore mean? A: It indicates the piston is 0.060 inches larger than the standard bore size, requiring the cylinder to be bored to match for proper fit and clearance.

Q: Can I install this piston kit without machining? A: No, the cylinder must be professionally bored and honed to the exact oversize specification before installation to ensure correct piston-to-wall clearance.

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