Cometic Gasket Top End Kit - Honda XR400R - Big Bore 440cc

When it comes to the professionals that we've amassed here at the XR's Only / 4 Strokes Unlimited Headquarters, Cometic Gasket Kits are at the top of the charts, particularly when assembling a big bore kit that includes any of our JE or Ross high compression piston kits.

Top end  gasket kits include an OEM quality steel cylinder head gasket, unlike other aftermarket kits that only offer the traditional "fiber type" cylinder head gaskets that eventually breakdown and lead to oil leaks. This is especially the case when a high compression big bore application is involved.

All Cometic Gaskets we offer meet or exceed OEM quality, durability and longevity and are available for both top end and bottom end engine applications at a fraction of the coast of Honda OEM gaskets and gasket kits. We stock complete Cometic Gaskets for your Honda as a kit or sold separately. All Cometic Top End Gasket Kits come with one steel cylinder head gasket, cylinder base gasket and four valve adjuster cover O-rings.
