Good To Know

Q: Can I install this standard bore kit without machining the cylinder? A: Only if the cylinder is within factory wear limits and glaze‑breaking with a ball hone is acceptable; otherwise a light hone is recommended for proper ring seating.

Q: Does this kit include the piston circlips? A: Yes, wrist pin circlips are included along with all necessary gaskets for the 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.
