Designed exclusively for Harley-Davidson Big Twin and Sportster engines

Butterfly-type carbs with a fully adjustable idle mixture screw and a changeable mid-range and high speed jet

Fully adjustable accelerator pump and a variable enrichment/fast idle device for improved throttle response, engine starting and warm-ups

Super E has a 1 7/8" (47.6mm) throat at the butterfly and a 1 9/16" (39.6mm) venturi and is recommended for use on any displacement Big Twin or Sportster

Super G has a 2 1/16" (52.3mm) throat at the butterfly and a 1 3/4" (44.5mm) venturi and is recommended for use on 74 cubic inch engines and larger where high performance modifications have been done or are planned (not recommended for smaller, lower compression engines)

If you are not sure which carburetor to use, we suggest the 1 7/8" Super E

Each complete carb kit includes: one S&S Super E or Super G gas carburetor, one S&S teardrop air cleaner assembly, one manifold, mounting hardware, fuel line, clamps, overflow line, one extra intermediate jet, two main jets, VOES tubing (when applicable), and installation and jetting instructions

NOTE: S&S Super E and G carburetors require the use of a two-cable, pull open-pull closed throttle assembly. If your bike is not equipped with one, a two-cable system must be purchased separately.
