Good To Know

Q: What does Size B mean?A: Size B indicates a slightly larger piston diameter than standard to allow for cylinder wear, often used for first oversize rebuilds. It provides a tighter fit for worn cylinders.

Q: Does this kit include the connecting rod bearing?A: No, the kit includes piston, rings, pin, and circlips; the connecting rod bearing is separate and must be ordered separately.

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