Idle adjustment of Keihin carbs can be annoying because the adjusting screw is somewhat hard to reach, in particular with stock air cleaners and large gas tanks. The Bates adjuster solves this problem once and for all. It features a flexible shaft and a large adjuster knob with knurled edge which allows carb adjustment without a screwdriver and as fast as you can say “****! I forgot my ******* tool roll in the garage!”

Measures 3 3/4 inches long.

Fits Keihin CV-Carburetors 1988 & Up.
