Description A lot of cylinder head heat transfres though the flanged rubber manifold into the carburetor, and the rubber flanges themselves may warp as a result, causing the fuel/air mixture to go leann which causes more heat – it’s a vicious cycle. These water jet, burr-free3/16″ thick phenolic heat blocks provide an effective barrier. Simply install between the cylinder head and rubber manifold. Two required per motorcycle. – $13.99 (set of 2)
