Super E Carburetor Kit For Harley Big Twin Evo 1984-1992

Maximum Performance for the Evolution Era: S&S Super E Carburetor Kit

The 1984–1992 era of the Harley-Davidson Evolution Big Twin is legendary for its reliability, but the factory carburetors of the time—the early butterfly style and the initial CV units—often left much to be desired in terms of raw performance. The S&S Super E Carburetor Kit (Part #11-0407) is the industry-standard solution to this problem. Designed specifically for the 1340cc (80″) Evolution engine, this kit replaces the entire fuel delivery system with the world-famous “Shorty” Super E. The results are immediate: easier starting, a more stable idle, and a ferocious increase in mid-range torque and top-end horsepower that brings your Evo to life like never before.

The “Shorty” Advantage: Engineering and Airflow

The Super E is affectionately known as the “Shorty” because its body is 1-1/8″ shorter than the vintage Super B model. This compact design serves two purposes: it fits perfectly between the cylinders on Evolution frames and allows the high-flow air cleaner to sit closer to the engine, providing better leg clearance for the rider. Inside the 1-7/8″ bore, S&S uses a precision-machined butterfly throttle. Unlike vacuum-operated stock carburetors that suffer from “lag,” the Super E provides a direct mechanical link to your wrist. When you twist the throttle, the air and fuel delivery is instantaneous, providing the crisp, aggressive “snap” that S&S is famous for.

Everything You Need in One Comprehensive Kit

One of the reasons the 11-0407 kit is a best-seller is its completeness. S&S takes the guesswork out of the installation by providing a matched system where every component is designed to work together.

• S&S Super E Carburetor: Pre-jetted for the 80″ Evolution engine for a smooth “out-of-the-box” experience.
• S&S Intake Manifold: A high-flow cast manifold that ensures a perfect seal and optimal intake velocity.
• Teardrop Air Cleaner: The iconic chrome S&S teardrop assembly, which not only looks the part but increases airflow by up to 14% over stock.
• Mounting Hardware and Gaskets: Includes all necessary O-rings, seals, and fasteners for a professional, leak-free installation.

Tuning Versatility and Modern Reliability

The S&S Super E is built to handle the demands of the modern road. It features a fully adjustable accelerator pump, allowing you to dial in the perfect “shot” of fuel to eliminate off-idle hesitation. The enrichment device simplifies cold starts without the need for a traditional choke cable, cleaning up the look of your handlebars. Additionally, the Super E is manufactured with high-grade components that are resistant to the corrosive effects of modern ethanol-blended fuels. Whether you are running a stock 80″ Evo or one with a Stage 1 cam and exhaust, the Super E is easily tunable to match your specific engine configuration, ensuring your Harley-Davidson runs at peak efficiency at any altitude.

Why Choose S&S for Your Big Twin Evo?

Choosing the S&S Super E Carburetor Kit is an investment in the longevity and soul of your motorcycle. For over 60 years, S&S Cycle has been the leader in V-Twin performance, and the Super E is their crown jewel. By upgrading your 1984–1992 Big Twin, you are choosing to ride a bike that pulls harder, sounds better, and responds exactly when you need it to.

From the city streets to the open highway, your Evolution deserves the best fuel delivery system on the market.

Note: This kit is designed for models using a 2-cable throttle system. 1984–1989 models may require minor cable adjustments or S&S-specific throttle cables for optimal fitment.
