Specs At A Glance

Good To Know

Q: Will this piston fit a stock, unbored cylinder? A: No, this is a .080 oversize piston at 86.00 mm and requires the cylinder to be bored and honed to match. Installing it in a stock bore will not work.

Q: How many kits do I need for my engine? A: Each kit covers one piston assembly. Order one kit per cylinder you are rebuilding, and confirm the bore size before purchase.

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