KEIHIN Idle Jet 40 (Manufacturer Part No: N424-21040)
This carburation part is designed for mechanics and riders who care about a clean idle. The KEIHIN Idle Jet 40 plays a crucial role in managing the air/fuel mixture at low RPMs. By replacing the original idle jet, it allows for fine-tuning the amount of fuel delivered during starting phases and at low throttle openings.
Designed as a replacement part for KEIHIN carburetors, this jet maintains the same purpose: to stabilize the idle, limit stuttering, and improve engine response at low RPMs when carburation requires adjustment. Ideal for tuning during maintenance or a carb kit, it integrates with jet sets and helps restore consistent carburation.
Before installation, check compatibility with your carburetor and retain the references. Always replace jets with suitable parts to maintain the safety and reliability of your machine on the road or track.
