MIKUNI Super BN Series Pilot Jet - 4-Pack N100606-115

A properly sized pilot jet is fundamental to carburetor tuning—it directly controls fuel delivery at idle and low-throttle operation, where engine responsiveness and smooth transitions begin. If your bike hesitates off the line, idles rough, or stumbles during low-speed maneuvers, the pilot jet is often the culprit. This genuine Mikuni component gives you the precision calibration needed to dial in your carburetor's baseline performance.

The Super BN Series pilot jet is engineered for compatibility across a wide range of Mikuni carburetors used in street bikes, pit bikes, and small-displacement engines. Made in Japan with Mikuni's exacting standards, this orifice-style jet delivers consistent fuel metering and repeatability across thermal cycles and load conditions. Whether you're tuning for elevation changes, seasonal riding, or a modified intake manifold, having the correct pilot jet size is essential for establishing a stable baseline before fine-tuning the needle and main jet circuits.
