Specs At A Glance

Good To Know

Q: Does installing this rod kit require splitting the cases? A: Yes, the crankcase must be split and the crankshaft pressed apart, so this job is best done by a machine shop or a builder experienced with two stroke bottom ends.

Q: Will this work with my stock piston? A: The kit restores original rod dimensions, so a stock or stock replacement piston can be reused if the cylinder and piston are still within service limits.

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