Description
Yamaha Wolverine X2 1000 Top-End Rebuild with Valves
The Yamaha Wolverine X2 1000 Master Top End Rebuild Kit combines two Standard (STD) piston kits and top-end gaskets with replacement intake and exhaust valves. This package provides broader top-end rebuild coverage when the pistons and valves both require replacement.
What This Master Top End Rebuild Kit Includes
- (1) Top End Gasket Kit
- (4) Intake Valves
- (4) Exhaust Valves
- (2) Standard (STD) Piston Kits
Master vs. Complete Top End Rebuild Kit
The Master kit adds four intake and four exhaust valves to the piston and gasket components. Therefore, it is the better match when inspection shows that the valves also require replacement.
If your existing valves remain usable, consider the Wolverine X2 1000 piston and top-end gasket package instead.
Inspect the Top End Before Assembly
Before installation, inspect the cylinders, valve seats, valve guides, and related cylinder head components for wear or damage. Also, verify piston-to-cylinder clearance and confirm that Standard (STD) piston sizing is correct for your engine.
Then, follow the correct Yamaha procedures and specifications for piston, valve, and cylinder head assembly.
