Super E Carburetor Kit For Harley Shovelhead 1966-1978

The Powerhouse of Fuel Delivery: S&S Super G “Shorty” Carburetor Kit

When engine displacement crosses the 100-cubic-inch threshold, standard carburetors become a significant bottleneck. The S&S Super G Carburetor Kit (Part #11-0421) is the specialized solution for high-performance Harley-Davidson Evolution and Twin Cam builds that demand massive amounts of air and fuel. With a 2-1/16″ (52.3mm) bore, the Super G is 1/4″ larger than the famous Super E, providing a substantial increase in CFM (cubic feet per minute) flow. This kit is not for the faint of heart; it is designed specifically for modified engines, strokers, and big-bore kits where maximum top-end horsepower is the primary objective. By installing the Super G, you are ensuring that your high-performance V-twin never starves for fuel at wide-open throttle, allowing your engine to reach its full mechanical potential.

Engineered for High-Output Custom V-Twins

The “Shorty” Super G inherits the legendary mechanical design that made S&S Cycle a racing authority. Because it is 1-1/8″ shorter than vintage performance carburetors, it provides a compact fitment that clears large fuel tanks and doesn’t interfere with the rider’s leg. Unlike vacuum-slide carburetors found on stock machines, the Super G utilizes a mechanical butterfly throttle. This creates a direct, instantaneous connection between the rider’s input and the engine’s response. For a large-displacement engine, this means the torque is available immediately, pulling hard from the mid-range all the way to the redline. This kit is the gold standard for pro-street builds, drag racers, and heavy-duty performance baggers that require a fuel system as aggressive as their engine internals.

Comprehensive Performance Kit for Seamless Installation

The 11-0421 kit is a complete intake transformation, curated by S&S engineers to provide a perfectly matched air-fuel path.

• High-Flow Super G Carburetor: Pre-jetted for large-displacement engines to provide a solid baseline for tuning.
• S&S Performance Intake Manifold: Precision-cast to match the increased bore size of the Super G for uninterrupted airflow.
• Chrome Teardrop Air Cleaner: A legendary design that uses a unique directional cone to reduce turbulence and increase air intake velocity.
• Adjustable Accelerator Pump: Allows for custom tuning of the fuel “shot” to eliminate hesitation on high-compression engines.

Advanced Tuning for Precision Riding

Reliability and tunability are at the core of the S&S philosophy. The Super G features an enrichment device that simplifies cold starting, doing away with traditional choke cables and keeping your handlebars looking clean. To ensure longevity on the modern road, S&S manufactures these kits with high-grade, ethanol-resistant seals and gaskets. This prevents the degradation often caused by modern pump fuels. Whether you are running a 103″, 110″, or 124″ crate engine, the Super G offers the adjustment range needed to achieve a crisp idle and smooth power delivery. It is a true performance investment that transforms the riding experience, turning a powerful engine into a refined, high-speed monster. Don’t let a small carb limit your build. Step up to the S&S Super G and experience the raw, unadulterated power that only a 2-1/16″ bore can provide.
