Kawasaki Ultra LX Jet Ski Master Engine Rebuild Kit +.25mm

Once cylinder measurements point to +.25mm piston kits, the rebuild needs more than guesswork. This master engine rebuild kit fits 2021-2022 Kawasaki Ultra LX Jet Ski models and helps bring the major engine components together before assembly starts.

The +.25mm sizing applies to the piston kits only. Because this kit includes rotating assembly, valve train, timing, bearing, and sealing components, it gives builders a strong path for a full engine overhaul.
