S&S, Super B carburetor kit

The predecessor of the Super E. The E was introduced in 1990 for all-round street use, the B came in 1975 for all out performance and is suitable for engines up to 100″. It has the identical 1-7/8″ diameter throat but a longer venturi. Perfect for high flow and high performance applications. Note that legroom will suffer due to increased overall length. An acceleration pump is not present and not needed. When kickstarting, pre-kick like twice or so, without ignition, to prime the motor and it’ll start just fine. Super E Air filter housings are not interchangeable. The B was used to power muscle bikes of their time, and they’re still nothing to joke about.
