Frequently Asked Questions

Q: Does this piston kit require cylinder re-boring or sleeving?
A: No. This kit features a standard 45.00 mm bore size designed specifically to drop into stock factory Nikasil bore cylinders without re-sleeving.

Q: Can I use standard aftermarket or OEM piston rings with this Wiseco piston?
A: No. Wiseco pistons must be fitted strictly with matching Wiseco rings, as ring types and ring land dimensions are specific to Wiseco designs and are not interchangeable.

Expert Pro-Tip: Always measure your cylinder bore taper and out-of-round using a dial bore gauge before dropping in a new piston assembly. Be sure to stagger your ring end gaps during assembly according to Wiseco specs, and apply clean two-stroke premix oil generously to the wrist pin bearing, wrist pin, and cylinder wall before sliding the cylinder over the new piston rings.
