Yamaha Raptor 660R Master Top End Refresh Kit

Refresh the upper end of your 2002-2005 Yamaha Raptor 660R with this Master Top End Refresh Kit from REV6. Designed for engines with a serviceable piston, this kit combines new intake valves, exhaust valves, a standard bore piston ring kit, and a top-end gasket kit to restore performance without replacing the piston.

Replacing the valves, piston rings, and gaskets together helps improve compression, reduce oil consumption, and simplify your rebuild. Additionally, completing these repairs while the cylinder head is apart helps reduce future downtime.

When This Master Top End Refresh Kit Is the Right Choice

Choose this kit when your piston remains within service specifications but the valves, piston rings, and gaskets need replacement. However, if the piston also requires replacement, the Top End Rebuild Kit or Master Top End Rebuild Kit is the better choice.

What This Kit Includes

• Intake Valves
• Exhaust Valves
• Top End Gasket Kit
• Standard Bore Piston Ring Kit

Compatible Yamaha Models

• 2002-2005 Yamaha Raptor 660R
