This throttle body was developed to fuel the now legendary Tribute 145 engines. The throttle body's two large 2 1/16" bores supply enough air for nearly any displacement engine. Manifolds are not available for engines under 124". Some stock parts from the original EFI system will be reused. Custom bike builders can choose either style, but most opt for the later Delphi style set up. The S&S® VFI module is required to operate these throttle bodies. S&S teardrop air cleaners are available. If another intake is desired, it must be fabricated by the builder. Modules and air cleaners are sold separately.
