EBC424-21-45 Pilotjet N424/21-45

This EBC N424/21-45 pilot jet is a brass tuning component used to manage the fuel mixture at idle and low throttle positions. The 45 size provides a specific flow rate that helps ensure a smooth transition to the main jet circuit. In Harley-Davidson tuning, the pilot jet is frequently adjusted to compensate for changes in engine configuration, such as the addition of a high-flow air cleaner. EBC is a leader in aftermarket fueling components, offering precise sizing for effective and predictable carburetor calibration. This product is sold in packs of 4, providing spares for multiple tuning sessions.
