Introduction
S&S ® Super B carburetor is a butterfly type carb with a fully
adjustable idle mixture screw and changeable mid range and
high speed jets. This carburetor does not have an accelerator
pump nor a conventional choke, but utilizes a mixture
enrichment device for starting. The Super B has a 17⁄8” (47.6mm)
throat at the butterfly and a 19⁄16” (39.6mm) venturi and is
identified by an “B” cast into the throttle return spring side of
the carb body below the cast in wording “S&S SUPER”.
DISCLAIMER:
S&S parts are designed for high performance, off road, racing
applications and are intended for the very experienced rider only.
The installation of S&S parts may void or adversely effect your
factory warranty. In addition such installation and use may
violate certain federal, state, and local laws rules and ordinances
as well as other laws when used on motor vehicles used on public
highways, especially in states where pollution laws may apply.
Always check federal, state, and local laws before modifying your
motorcycle. It is the sole and exclusive responsibility of the user
to determine the suitability of the product for his or her use, and
the user shall assume all legal, personal injury risk and liability
and all other obligations, duties, and risks associated therewith.
Chrome Plating the Carburetor
NOTE - S&S does not recommend chrome plating the Super B
carburetor. Proper preparation to achieve a good chrome finish
requires polishing using buffing compounds. These materials
invariably plug air and/or fuel passageways and feed holes
regardless of the precautions taken.
Plugged passageways and feed holes and the polishing and
chrome plating processes can alter operating tolerances
machined into the parts in critical areas. Additionally, pieces
of chrome may break off and plug a passageway which could
potentially affect the fuel mixture resulting in damage to the
engine. S&S voids any warranty if the carb body and/ or bowl
is polished, chrome plated or altered in any way.

Throttle Requirements
NOTE - S&S Super B carburetor requires the use of a two cable,
pull open - pull closed throttle assembly. Any chassis including
1980 and earlier stock models equipped with a single cable
throttle mechanism requires conversion to a two cable, pull open
- pull closed type.
Single, braided wire cable throttle mechanism can not
mechanically close throttle. If throttle inadvertently sticks in
open position, loss of control of motorcycle and personal
injury to you or others may result.
S&S offers an optional two cable throttle assembly designed to
convert most any chassis not equipped with a two cable system.
This kit is available with 48” long cables and can be ordered
separately. See the description below.
Stock models from 1981 to present have a two cable throttle and
should not require conversion. The stock cables on these chassis
can be used but must be modified.
Optional S&S Two Cable Throttle Conversion Kit - for chassis not
equipped with two cable throttle - Part #19-0229 - Includes
complete throttle assembly with grips for both bars and two 48”
(cable housing length) cable assemblies. Fits 1” O.D. handlebars
and can be used on most chassis requiring up to 48” long cables.
Special bushings are available for use with older 7⁄8” O.D. handle
bars, Part #19-0235.
Carb Installation
Read instructions thoroughly before starting work to familiarize
yourself with installation procedure.
NOTE - Installation of S&S Super B carb kits on some models is
easier with gas tanks removed. Some owners may elect to
perform installation without removing gas tanks. This option has
been left to discretion of individual. If one elects to remove tanks
or must disassemble any other stock parts, S&S recommends
owners consult appropriate service manual for their model
motorcycle for reference.
1. Remove Old Carburetor
● Gasoline is extremely flammable and explosive under
certain conditions and toxic when breathed. Do not smoke.
Perform installation in a well ventilated area away from
open flames or sparks.
● If motorcycle has been running, wait until engine and
exhaust pipes have cooled down to avoid getting burned
before performing any installation steps.
