These high quality phenolic resin heat insulators protect and insulate your Amal or Mikuni carburetors from power draining heat. Keeping the carburetors cooler will also keep the intake charge cooler resulting in more horsepower. Phenolic resin does not transfer heat as efficiently causing an insulating effect. Spacers measure .065" (1.66mm) thick.
The heat insulators fit the Commando 750/850 intake ports and will work with OEM or aftermarket manifolds. Bolt spacing is 2" (51mm) and the ID is 1.27" (32mm). Sold in sets of two.
