KEIHIN Idle Jet 38 — Manufacturer Ref: N424-26038
This idle jet from KEIHIN is designed for fine-tuning fuel delivery. Numbered "38," it defines the fuel flow at idle and directly affects the air/fuel mixture when the engine is running at idle or low RPMs. As an original KEIHIN part, it fits into the appropriate carburetor circuits to achieve a stable idle and a low RPM response that meets the desired settings.
Ideal for motorcyclists who maintain their carburetor, this jet allows for adjusting the richness at idle in addition to needle and mixture screw adjustments. Installation and removal require precision: carefully clean the jet well and use the appropriate tools to avoid damaging the part. If you are unsure of the necessary size or precise setting, have the carburetion checked by a professional.
Replace your worn jet or change the size to safely test different idle settings — a simple intervention that is part of basic carburetor maintenance.
