S&S Cycle 11-0412 Super E Partial Carburetor Kit for 1936-84 Big Twin FL/FX

The S&S Cycle Super E Partial Carburetor Kit (11-0412) delivers proven performance gains for 1936–1984 Harley-Davidson Big Twin FL and FX models. This partial kit includes the carburetor, S&S chrome teardrop air cleaner assembly, and hardware — but does not include a manifold, making it the ideal choice for builders using a custom stroke and bore setup that requires a specialty intake manifold, or for riders upgrading from an existing S&S Super B carburetor.

The Super E's 1-7/8" (47.6 mm) bore at the butterfly and 1-9/16" venturi generate higher air velocity compared to the larger Super G, translating directly into stronger low- and mid-range throttle response and power. It is recommended for Big Twin engines up to 100 cubic inches displacement.

Key Features:

• 1-7/8" bore / 1-9/16" venturi — optimized for engines up to 100 cu. in.
• Four fuel delivery ports for improved, consistent throttle response
• O-ring sealed idle mixture screw for precise, leak-free tuning
• Adjustable accelerator pump for quick throttle response and easy starting
• Variable-position enrichment starting system — no choke, leaves bore unobstructed for maximum airflow
• Dual-cable throttle spool — accepts stock 1981 and later pull-open/pull-close throttle cables on all Big Twin models
• Chrome finish with natural-finish carburetor body

Kit Includes:

• S&S Super E carburetor
• S&S chrome teardrop air cleaner assembly
• Mounting hardware, gaskets, seals, and hoses
• Jetting and installation instructions
• Manifold not included

Note: This partial kit is intended for 1936–1984 FL and FX Big Twin models with standard gas tanks. A separate manifold must be sourced. Not legal for sale or use in California or on any EPA pollution-controlled motor vehicle.
