Boyesen RAD Valve Gasket RG35 – Yamaha Blaster 1988–2006

Description

Boyesen RAD Valve Gasket for Yamaha Blaster

The Boyesen RAD Valve Gasket RG35 is a genuine replacement gasket for Boyesen RAD Valve assemblies used on the Yamaha YFS200 Blaster. Replace a damaged, compressed, or leaking gasket to help maintain a dependable seal between the RAD Valve and the engine.

An intake gasket leak can allow unmetered air into the engine. This may cause a hanging idle, difficult carburetor tuning, inconsistent performance, or a dangerously lean air-fuel mixture. Always inspect the gasket whenever the RAD Valve is removed.

This gasket is specifically intended for compatible Boyesen RAD Valve assemblies. It is not advertised as a replacement gasket for the original Yamaha reed cage.

When Should the RAD Valve Gasket Be Replaced?

Replace the gasket whenever it is torn, hardened, crushed, or no longer seals correctly. Installing a fresh gasket is also recommended whenever the RAD Valve is removed during engine rebuilding, reed inspection, carburetor service, or intake-system repairs.

The sealing surfaces should be clean, flat, and free of old gasket material before installation. After assembly, a complete engine leak-down test is recommended to confirm that the intake system is properly sealed.
