Description

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

Once cylinder measurements confirm the need for an oversize piston, it’s the perfect time to complete a full engine rebuild. This master engine rebuild kit is designed for 2007-2011 Kawasaki Ultra LX Jet Ski models and combines the major components commonly replaced during a complete overhaul into one convenient kit.

The +.25mm designation applies to the piston kits only. Instead of piecing together individual components from multiple sources, you can move through your rebuild with a matched collection of parts designed to work together.

What This Kit Includes

• Crankshaft
• Connecting Rods
• Piston Kits +.25mm
• Complete Gasket Kit
• Oil Pump Chain
• Intake/Exhaust Valves
• Cam Chain
• Crankshaft Ball Bearing
• Crankshaft Outer Bearings
• Crankshaft Bearing Inner Bearings
• Crankshaft Main Bearing
• Connecting Rod Bearings

Why Builders Step Up to a Master Kit

When an engine is already apart for machining and inspection, replacing the major wear components during the same teardown helps reduce repeat labor and gives the rebuild a stronger foundation.

• Install +.25mm piston kits after cylinder measurements support the next oversize.
• Replace the rotating assembly with a new crankshaft and connecting rods.
• Refresh the valve train before the cylinder head goes back together.
• Install new bearings, timing components, and gaskets during one rebuild.
• Complete the overhaul with one coordinated parts kit.
