S S Super E idle screw Stainless Brass (Short Version) This replaces the idle screw and lets you adjust the idle while you are on the bike without using a screw driver. If your bikes idle changes in different weather or if you want to warm it up without running the choke and loading it up, this works great, it is made for Stock S S super E Carbs but may work with others with 8-32 Threads. This was made to work with aftermarket Enrichener?s. I do make another version that is longer but will not work with aftermarket Enrichener?s. Made of solid 303 stainless steel Brass. Overall length is approximately 2 inches long. American made. Please email questions before bidding. Thanks for looking. Please Note: if you are running 5 gallon Fatbob tanks you need to check for enough clearance between the tank and the air cleaner for your fingers.
