S&S Cycle Carburetors & Accessories

S&S Cycle Carburetors: The Gold Standard for V-Twin Fueling

When it comes to carburetion on Harley-Davidson and V-twin motorcycles, few names carry the weight that S&S Cycle does. Founded in 1958, S&S has spent over six decades earning its reputation on the racetrack and the open road, and nowhere is that legacy more evident than in their lineup of carburetors and carburetor accessories. These are not bolt-on afterthoughts — they are the product of generations of American engineering, refined through real-world racing and built entirely in the USA.

The Super E & Super G: Icons of the Aftermarket

The two crown jewels of the S&S carburetor catalog are the Super E and Super G — butterfly-type carburetors engineered specifically for Harley-Davidson Big Twin and Sportster engines. The Super E, with its 1-7/8" bore, is a versatile performer that works across a wide range of displacements, from stock motors to moderately modified builds. The Super G steps up the game with a 2-1/16" throat at the butterfly and a 1-3/4" venturi, making it the go-to choice for 90-cubic-inch and larger high-performance or modified engines.

Both carburetors share a feature set that makes them exceptionally tuner-friendly. Key features include:

• Four fuel delivery ports for superior throttle response
• Fully adjustable idle mixture screws, angled for easy accessibility even with large fuel tanks
• Changeable intermediate and main jets to dial in fuel delivery for any combination
• Adjustable accelerator pump for crisp off-idle response and easy cold starts
• 360° fuel inlet fitting for flexible installation in tight spaces
• Variable position enrichment starting system for reliable cold-weather starts

Select models also feature S&S's exclusive Enduraguard coating — a satin black finish that provides exceptional heat and chemical resistance for long-term durability.

Complete Kits & a Deep Accessories Catalog

S&S Cycle doesn't just sell carburetors — they sell complete, ready-to-install systems. The Super E and Super G carb kits include the carburetor with updated fuel delivery ports, the iconic S&S teardrop air cleaner assembly, intake manifold, mounting hardware, fuel line, clamps, overflow line, spare jets, VOES tubing (where applicable), and full installation and jetting instructions. Everything arrives in a single kit to minimize downtime.

Beyond complete assemblies, S&S supports the long-term ownership of their carburetors with a comprehensive accessories lineup: float pins and bowls, accelerator pump springs and plungers, idle mixture screw springs, throttle return springs, pump adjustment screws, cable clamps, and more. Whether you're doing a full rebuild or simply freshening up a high-mileage carb, the parts ecosystem is deep and readily available.

Why S&S Carburetors Stand Apart

S&S carburetors are made in the United States — a distinction that matters for quality control and consistency. The brand's motorsport heritage, which spans Bonneville Salt Flats speed records to American Flat Track championships, means every design decision is validated under extreme conditions before it reaches the street. For any Harley-Davidson owner running a carbureted motor — whether stock, modified, or full custom — S&S Cycle's carburetor lineup represents a proven, tunable, and durable upgrade that has stood the test of time across countless builds.
