Each carb kit includes an S&S Super E or Super G gas carburetor, S&S teardrop air cleaner assembly, manifold,(unless noted) mounting hardware, fuel line, clamps, overflow line, one extra intermediate jet and two main jets, VOES tubing (when applicable), installation and jetting instructions
Super E has a 17/8 (47.6mm) throat at the butterfly and a 19/16 (39.6mm) venturi and is recommended for use on Big Twin or Sportster engines up to 100-cubic-inch
Super G has a 21/16 (52.3mm) throat at the butterfly and a 13/4 (44.5mm) venturi and is recommended for use on 90-cubic-inch and larger high-performance and modified engines
21/16 G is not recommended for smaller, lower compression engines
If there is a doubt as to which carburetor to use, we suggest the 17/8 Super E
