KEIHIN 42 Idle Jet — original part by KEIHIN, designed for demanding riders who maintain their carburetors. This Ø42 jet directly influences the management of the air/fuel mixture at idle and during low RPMs, ensuring a stable idle and a smoother throttle response. Compatible with Keihin-type carburetors, it is intended for replacement during maintenance or fine-tuning of the idle circuit.
Manufactured with KEIHIN's expertise, this jet is ideal for maintenance sessions, carburetor restoration, or for fine-tuning the idle mixture after intake or exhaust modifications. Easy installation: it replaces the original jet in the idle well of the carburetor. Be sure to check the rest of the circuit (needle, float chamber, passages) for effective tuning. For installation, use the appropriate tools and adhere to the torque specifications recommended by the carburetor manufacturer.
A good idle jet is one of the essentials to have in your toolbox to keep your motorcycle lively and responsive on a daily basis.
