You've probably already experienced tempermental off-idle acceleration when ambient conditions like temperature, humidity, and altitude change. And, you know what a pain it is to adjust the stock mixture screw on the FCR carburetor. The solution is adjustment when conditions change, and the Zip-Ty Fuel Screw allows fast and easy adjustment. This fuel screw is carved from 7075 T7 Aluminum for improved tensile strength and have a redesigned tip taper and seating shoulder to accomodate the newest (3rd generation) Keihins. They feature a knurled forend for easy grip, anodizing for longevity, and laser etching for adjustment accuracy. The Zip-Ty Racing screw allows you to fine tune your bike easily and quickly with just your fingers - trail or track side.
