Zipty Screw by MOOSE OFFROAD HARD - PARTS: a mixture screw designed for demanding riders. Machined from 7075 T-7 aluminium and anodised black, this compact screw withstands the rigours of off-road use while showcasing a neat and corrosion-resistant finish. The redesigned tapered stud facilitates insertion and adjustment, providing a precise grip for fine-tuning the mixture setting.
Designed to fit Keihin FCR carburettors on modern motorcycles, the Zipty Screw allows for manual adjustment of the air/fuel mixture — a useful adjustment for standing starts or to refine throttle response. Supplied with an O-ring, washer, and reinforced spring, it replaces the original screw without any modifications and maintains the fuel circuit's seal.
Compact and robust, the Zipty Screw is a practical accessory for those seeking more accessible mixture adjustments and quick intervention on the carburettor, whether in competition or on a ride. Particularly suitable for models like Honda CRF 150, Yamaha YZ 250F, and KTM EXC 530.
