Top End Rebuild Parts for the 2004–2007 Yamaha Rhino 660
If your Rhino 660 has low compression, oil use, or top-end wear, this kit provides the main parts listed for the repair. It combines a 102mm piston kit with fresh gaskets and five valve stem seals.
Because the piston is sized for a 102mm bore, check the cylinder bore during teardown. Then, compare the bore measurement with the piston specs before assembly.
This Kit Includes
- High-performance piston kit with 102mm bore
- Complete top end gasket kit
- (5) High-temperature valve stem seals
What This Kit Covers
This package supports a top-end rebuild when the original cylinder remains usable. However, a cylinder is not included. If your rebuild requires a replacement cylinder, compare this kit with the 2004–2007 Yamaha Rhino 660 Big Bore Complete Top End Rebuild Kit.
