Good To Know

Q: Does an overbore piston kit require machine work? A: Yes, a .040 overbore piston needs the cylinder bored and honed to the matching 85.00 mm size before assembly. Confirm clearance specs with your service manual before installation.

Q: Can I install just one piston from this kit? A: This kit services a single cylinder, so check how many cylinders your rebuild needs before ordering. Mixing bore sizes across cylinders is not recommended.

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