KEIHIN Idle Jet 45 (Manufacturer part number: N424-24045) — Original KEIHIN part dedicated to fine-tuning the idle fuel mixture. This 45 jet fits on carburetors requiring this diameter and allows for adjusting the air/fuel mixture passage at low RPM.
Designed as a replacement part, this jet is intended for riders concerned about stable idling and precise adjustment of the mixture screw. Before installation, check compatibility with your carburetor and thoroughly clean the jet well to avoid any blockage. Install and tighten moderately to preserve the threading; in case of wear or micro-blockage, replace the jet to restore healthy engine behavior at startup and low RPM.
Practical tips: keep removed parts clean, check the entire carburetion system (needle, main jet, float) during maintenance, and test the adjustment on the road after installation. A simple yet essential part for a well-tuned carburetor and smooth idling.
