KEIHIN Idle Jet 52 — Manufacturer Ref: N424-21052
Original KEIHIN idle jet, size 52, designed for fine-tuning fuel mixture. This jet (pilot jet) operates during the idle phase and at very low throttle openings: it precisely regulates the fuel flow to ensure stable intake at low RPM.
Ideal for fuel mixture adjustments and maintenance operations, this jet allows for the adjustment of the air/fuel mixture at idle to achieve a more linear response at low RPM. Suitable for carburetors equipped with a size 52 jet; please check compatibility with your carburetor model or original reference before installation.
Practical tips: always proceed with a gradual and controlled adjustment during tuning, and entrust the intervention to a qualified mechanic if necessary. Product delivered as manufactured by KEIHIN.
