A must for all four strokes using the Keihin FCR carb. To get the best throttle response from your engine you must properly adjust the low speed fuel mixture screw. Due to the difficulty of adjusting the stock screw. Mino has designed a billet extended fuel mixture screw that can be adjusted by hand. Manufactured to the exact tolerances of the stock screw with a built in thumb wheel for easy adjustments.
