Good To Know
Q: Does this piston kit include all necessary rings? A: Yes, the kit comes with piston rings and a wrist pin, though you should reuse your original clips if applicable.
Q: Can I use this on a standard bore cylinder? A: This is .010 over size, so it requires a cylinder that has been bored or honed to 83.25mm; it will not fit a standard bore cylinder.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
