Genuine Keihin parts provide the best replacement or calibration solution for your Keihin carburetors.  Do not use an imitation, nothing substitutes for OEM quality and Keihin parts are guaranteed to be the best because of high manufacturing tolerances.  The remote idle stop screw extends the idle speed adjustment to the side of the carbs.  

Threads measure 5mm x 0.8mm x 32mm long.  This idle adjuster extension is meant for Keihin CR carburetors but will work on ANY carburetor with this size of threading for the idle stop screw.
