YOST ADJUSTABLE IDLE/AIR SCREW CV

Yost has been making great performance parts for all Harley Davidson model stock and aftermarket carburetors for years! Stock CV carburetors have a small plug on the bottom backside of the carburetor that caps off access to the idle/air mixture screw. When doing any upgrades, tuning, or performance work, having access to that is imperative.  This kit includes a screw to help remove the plug along with a new spring, washer, O-ring, and most importantly a new screw. The stock small screw is inboard of the body and requires a tiny flat head screwdriver. Replace it with the Yost screw which is longer and knurled to make adjustments easy and capable of being done on the fly!  Knurled and slotted head for easy adjustment Includes brass or stainless-steel screw, O-ring, washer, and spring Made in the U.S.A
