KEIHIN Idle Jet 45 — manufacturer reference: N424-26045
Replace or calibrate the heart of your fuel system with this idle jet from KEIHIN. Numbered 45, it plays a role in adjusting the air/fuel mixture at low RPMs to ensure stable idle and smooth throttle response when the engine is running at low speed.
Ideal for riders who are repairing their carburetor or adjusting the mixture after modifications (filter, exhaust, altitude), this jet allows you to restore the pilot setting when the original is clogged or worn. Note: the size selection must correspond to the type of Keihin carburetor and the overall setting of the motorcycle — a jet that is too rich or too lean will alter the behavior of the idle.
Usage tips: clean the bowl and passages before installation, check the needle and float, and perform idle tests after installation. If necessary, have the adjustment checked by a tuner or a specialized workshop for precise setting.
