S&S Cycle Black Super G Carb Kit Features: S&S Cycle T143 requires either a S&S Super G or Super D. carburetor kit which includes the carburetor, manifold, air cleaner kit, and all hardware required. For improved rideability, S&S Cycle recommends the Super G carburetor. It has better low RPM throttle response and offers better control in lower RPM applications. The Super D carb kit is recommended for race applications where high RPM horsepower is the most important factor. The Super D carb kit is not recommended for use on Touring models. The length of the carburetor and air cleaner assembly makes it very hard to reach the rear brake pedal. Recommended for Dyna models with mid controls only. Note: Air cleaner assemblies included with these carburetor kits do not include air cleaner covers. Stock 1999-later air cleaner or any S&S Stealth air cleaner covers may be used.
