About This Product
This size 175 main jet is designed for Keihin CV carburetors, providing a precise fuel flow for 1988 to 2006 XL Sportsters and 1990 to 2006 Big Twin models. It is an excellent replacement for OEM 27090-89, often used when upgrading intake or exhaust systems to ensure the engine does not run too lean at high RPMs. These jets are sold as a pack of five, ensuring you have plenty on hand for the bench. Machined to exacting tolerances, they offer the consistent performance required to keep your Harley running smoothly across the entire powerband. Proper jetting is the key to engine longevity and power, and these jets deliver the quality needed for a perfect tune.
Manufacturer part number: 540047.
