This adapter allows for the installation of OEM or aftermarket air cleaners with recessed backing plate on Keihin CV carburetors. At least that’s what it is intended for, but of course, you can mount any air cleaner, carb cover or air horn with a Tillotson, Bendix or Keihin bolt pattern. It is also useful with large or low mounted gas tanks, because it positions the air cleaner further to the right by 21 mm.

Running an S&S Super E or G carb on Knuckleheads and Panheads results in the Teardrop air cleaner sticking out pretty far and interfering with your right knee. This low profile version features a shortened cover and a modified base plate which reduces the overall height of the air cleaner assembly by 25 mm. Thus you gain more legroom and the whole air cleaner tucks closer to the engine. Looks good on other models, too.

The S&S Super E and G carburetors are specifically designed for Harley-Davidson Big Twin and Sportster engines. They feature adjustable accelerator pump for instant throttle response at any rpm. The ejector nozzle is located in line between the main discharge tube and the butterfly for undisturbed air flow. With the rider in mind the idle mixture screw has been angled for greater accessibility even with 5 gal. gas tanks. The enrichment device also was refined with a large variable position lever attached to the air cleaner backplate where it is easy to operate even with thick gloves. The throttle spool assembly is designed for later style two cable pull open - pull closed throttle. Cables are not included and must be purchased separately. Following the tradition a teardrop shaped air cleaner has been retained but it was redesigned to reduce the installed lenght of the carb assembly. The new filter element has 19% more filtering area and combined with other design changes makes up to 14% more flow. S&S Super E & G are approximately 40 mm shorter than Super B carbs and provide easy clearance for Fat Bob tank applications and good rider comfort....
