Boyesen Power Reeds - Aftermarket Cylinders
MAXIMUM POWER IS ACHIEVED THROUGH AIR INTAKE, ACCELERATION, AND DISTRIBUTION
Dual-stage Boyesen Power Reeds for the aftermarket PJS Kawasaki JS440 / JS550 and West Coast Kawasaki JS550 cylinders work in unison to perform efficiently throughout the entire powerband. The difference in stiffness between the top reed and the bottom reed allow the reeds to respond quickly and accurately to changes in engine pressure. This translates into quicker acceleration, crisper throttle response and increased horsepower throughout the powerband.
