TRX250R Cometic Top-end Gasket Set with CR Style Head Gasket 68mm (Stock Cylinder)
This is a great little hop up trick for a stock 250R. This head gasket is paper thin at only .011 thick. It actually would raise the compression a bit too much for pump gas, so we supply two base gaskets raising the cylinder up slightly. This acts like mild porting. It sets the compression for pump gas and picks up about 4 HP with a wider power curve and more bottom-end power.
Cometic meets the needs of each specific gasket by using materials to match. Even the basic top end gasket kit features different materials for each gasket. The head gasket is constructed from non-asbestos, flexible graphite that is laminated to a stainless steel core. The manifold and base gaskets are constructed from non-asbestos nitride rubber-bound fiber. Cometic also includes copper gaskets where needed.
Cometic designs and builds their gaskets in the U.S.A.
NOTE: This is kit is for a stock cylinder and is not a big bore gasket set
