Zipper’s has the new black-finish S&S® E/G carburetors, with or without a ThunderJet® installed, in stock and ready to ship. The jet-black finish completely alters the look, and performance is enhanced with a +.100” ven- turi bore increase and the addition of the ThunderJet® third fuel circuit. You can purchase a black carb only to upgrade your existing S&S®-equipped bike or buy a complete kit with a black ThunderJet®-equipped carburetor included – a Zipper’s exclusive!
