MIKUNI MKC140 JET – Manufacturer reference: N100604-140
Original part by MIKUNI, this MKC140 jet is aimed at demanding riders who maintain or tune the carburation of their motorcycles. Designed for use with Mikuni MKC-type carburetors, it allows for adjustment of the air/fuel mixture calibration during maintenance, preparation, or restoration operations.
Ideal for replacing a worn jet or modifying the richness for a more precise adjustment, this jet integrates into the fuel circuit to influence the amount of fuel injected. It is suitable for tuning operations (main, idle depending on setup) carried out by riders and mechanics concerned with engine behavior: throttle response, idle stability, and smoothness in acceleration.
Before installation, check compatibility with your carburetor and proceed with gradual adjustments to achieve the desired air/fuel ratio. For any advanced tuning operations, the intervention of a professional or a tuner is recommended.
