Brand: KEIHIN — Manufacturer reference: 99101-357-1420
Calibrated main jet No. 142 by KEIHIN, designed for carburetors that seek precise air/fuel mixture adjustment at wide open throttle. A simple and direct replacement part, ideal for replacing a worn jet or for fine-tuning the carburetion during a detailed adjustment. Allows for adjusting the richness during mid to high RPM phases so that the engine "breathes" properly and the motorcycle responds as expected to the throttle.
Easy to handle for DIY enthusiasts and preparers, this jet integrates into tuning and maintenance operations of the carburetor. Bring the right parts for your rides and tuning sessions — a small component that plays a big role in engine response and operational consistency.
