Good To Know
Q: Will this piston kit work with stock cylinder? A: Yes, the .040 over bore requires honing or boring the cylinder to match the oversized piston, but it is a direct fit after machining.
Q: Does this kit include a circlip or clip? A: The wrist pin is included but circlips are not; please reuse your original circlips or purchase new ones separately.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
