KEIHIN Idle Jet 85
Manufacturer reference: N424-35085
KEIHIN idle jet size 85, designed for carburetors from the same manufacturer. It is intended to fine-tune the air/fuel mixture at low RPMs, directly affecting the richness at idle and during the initial throttle openings. This simple and targeted part allows for adjusting the engine's behavior when idling or during brisk acceleration at low throttle openings.
Used during carburetion adjustments, this jet is the component to replace to correct an irregular idle, difficult cold starts, or a need to modify the richness at low RPMs. Its replacement requires disassembling the carburetor and fine-tuning to achieve a stable idle and smooth response at small throttle openings.
Compact and robust, the KEIHIN 85 jet is aimed at motorcyclists and mechanics who work on carburation by hand, with a focus on precision in mixture adjustments. Always check the reference before installation.
