S&S CYCLE Main Jet - .102" - 5-Pack 11-7251

Precise fuel delivery is the foundation of reliable engine performance, and main jet sizing directly impacts your carburetor's ability to supply the correct fuel-air mixture across all throttle positions. An undersized main jet starves your engine under load, while an oversized jet floods the circuit—both scenarios compromise power and efficiency. The S&S Cycle .102" main jet is engineered to deliver optimal metering for stock and mildly modified engines, giving you the tuning flexibility to dial in peak performance without guesswork.

S&S Cycle is a trusted name in carburetor calibration, and this 5-pack ensures you have spares on hand for testing, replacement, or future builds. Whether you're fine-tuning a stock H-D engine or optimizing a performance setup, having the right main jet size eliminates lean-condition hesitation and maximizes throttle response.
