About This Product
This size .40 slow jet is designed for Keihin CV carburetors, acting as a direct replacement for OEM 27281-92. It is suitable for 1988 to 2006 XL Sportster models and 1990 to 2006 Big Twins. Sold as a pack of five, these jets allow for precise calibration of the pilot circuit, which controls the engine from idle up to about one-quarter throttle. If you are looking to restore factory-spec performance or need to lean out the idle mixture for specific environmental conditions, these high-quality jets provide the accuracy and reliability needed for a professional-grade carburetor tune-up. They are essential components for maintaining the smooth, predictable throttle response that the Keihin CV carburetor is known for.
Manufacturer part number: 540052.
