Super E Carburetor For Harley

The Legend of Performance: The S&S Cycle Super E “Shorty” Carburetor

In the world of American V-Twin performance, few names carry as much weight as S&S Cycle. The Super E Carburetor has spent decades at the top of the food chain, becoming the go-to upgrade for riders of Shovelheads, Ironheads, Evolutions, and Twin Cams alike. Known affectionately as the “Shorty,” the Super E features a body that is 1-1/8″ shorter than the previous Super B model, allowing it to fit perfectly between the cylinders without protruding excessively or interfering with the rider’s leg. Whether you are looking to wake up a stock 883 Sportster or provide enough fuel for a built 96-inch Stroker, the Super E is engineered to deliver a perfect air-fuel mixture across the entire RPM range.

Unmatched Throttle Response and Horsepower

The primary reason riders switch to an S&S Super E is the immediate and visceral change in power delivery. Unlike the stock constant-velocity (CV) carburetors found on most factory Harleys—which rely on vacuum to lift a slide—the Super E utilizes a butterfly-style throttle. This provides a direct mechanical link between your wrist and the intake tract. When you twist the throttle, the fuel delivery is instantaneous. Coupled with a highly efficient 1-7/8″ (47.6mm) bore, the Super E increases airflow significantly over stock units, resulting in noticeable gains in both peak horsepower and mid-range torque. It is the ideal choice for engines up to 100 cubic inches that require crisp, reliable performance on the street or the strip.

Precision Tuning and Adjustability

One of the greatest strengths of the Super E is its user-friendly tunability. S&S has designed this carburetor to be serviced and adjusted with basic hand tools. It features an enrichment device for easy cold starts, eliminating the need for a traditional cable-operated choke.

• Intermediate and Main Jets: The carb uses a dual-jet system that allows for fine-tuning of the cruising range and wide-open throttle separately.
• Adjustable Accelerator Pump: This allows you to dial in the perfect “shot” of fuel to eliminate off-idle hesitation, ensuring smooth acceleration every time.
• Idle Mixture Screw: Located for easy access, allowing you to maintain a perfect, steady “potato-potato” idle regardless of altitude or temperature changes.

Technical Fitment and Compatibility

The Super E is a versatile platform designed to fit a wide array of Harley-Davidson motorcycles.

• Big Twins: Fits Knucklehead, Panhead, Shovelhead, and Evolution engines (standard 2-bolt manifold mounting).
• Sportsters: Excellent upgrade for Ironhead and Evolution Sportster models from 1957 through 2006.
• Fuel Compatibility: Engineered to handle modern pump gas, including ethanol blends, with high-quality internal seals and gaskets.
• Installation: For a complete conversion, it is highly recommended to use the S&S-specific intake manifold and high-flow air cleaner assembly to ensure maximum airflow velocity.
