Good To Know

Q: Does this kit fit my 1991-1995 Yamaha WaveRunner VXR 650? A: This kit is listed for those model years and the 650 engine, but the cylinder must be at stock 77.00mm bore for a standard piston to fit correctly. Q: What comes in the kit? A: A Wiseco piston, matched rings, wrist pin, and circlips are included, so gaskets and bearings are typically ordered separately.

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