The Super D carburetor was designed for racing applications and should be considered a custom installation. A certain amount of fabrication and engineering will be required to adapt this performance carburetor to your motorcycle. S&S Super D carburetor is designed exclusively for large displacement big twin engines. It is a butterfly carb with a fully adjustable idle mixture screw with replaceable mid range and high speed jets. Additionally, it has a tuneable air bleed circuit. It doesn’t have an accelerator pump or a conventional choke, instead it utilizes a mixture enrichment device for starting.
Requires additional purchase of #43 Air Bleed Jet
