Yamaha Raptor 660R Master Engine Refresh Kit

Refresh your 2002-2005 Yamaha Raptor 660R engine with this Master Engine Refresh Kit from REV6. Designed for engines with serviceable major hard parts, this kit combines the most commonly replaced wear components with a complete valve replacement to help restore reliability, compression, and performance.

Replacing the valves, piston rings, crankshaft bearing, cam chain, gaskets, seals, and water pump components during one teardown helps simplify your rebuild and reduces the time spent sourcing individual parts. As a result, you can confidently freshen your engine without replacing the crankshaft, cylinder, or piston.

When This Master Engine Refresh Kit Is the Right Choice

Choose this kit when your crankshaft, cylinder, and piston remain within service specifications but the engine’s wear components and valves need replacement. However, if your rebuild also requires a new piston, cylinder, or crankshaft, the Yamaha Raptor 660R BIG BORE Master Engine Rebuild Kit is the better choice.

What This Kit Includes

• Intake Valves (3)
• Exhaust Valves (2)
• Cam Chain (1)
• Crankshaft Bearing (1)
• Standard Bore Piston Ring Kit (1)
• Complete Gasket Kit (1)
• Water Pump Rebuild Kit (1)
