These high quality kits come with all parts needed to refresh your Hayabusa cylinder head. These new kits include the new triple groove Kibblewhite Black Diamond Stainless steel valves in either stock or +1mm oversize. This new stem and keeper design helps reduce the chance of a dropped valve by increasing the surface contact area of the keeper and the valve. The Hayabusa Cylinder Head Kits contain: stainless steel valves in either stock or 1mm oversize, triple groove keepers, titanium retainers, 65 pound valve springs, special spring bases, and valve seals.
Whether you're racing a 50cc Pocket bike or a 550hp Turbo Street bike WWB has all the bearings to suit your needs: Front and rear wheel bearings and seals, transmission bearings, crank bearings, swingarm needle bearings. They also specialize in their hand made Ceramic Hybrid bearings
The MPS In Tank Fuel Pumps flow enough to support 650 horsepower and are a direct replacement to the factory fuel pump. The kit comes with all necessary hardware and instructions for an easy installation. Made in USA for long reliable service.
The output shaft support has a round steel anchor that is bolted to the swingarm pivot. The plate slides over the steel anchor and bolts to the cases with the bolts provided. An extended snout countershaft sprocket bolt then rides in the bearing fitted to the plate. This supports the end of the transmission output shaft preventing broken shafts and engine cases. A longer clutch pushrod is included. The output shaft support can be used with hand or slider clutches. If you have a “grudge bike” you need one of these!
