About Boysen Reeds:
Boyesen's innovative patented dual-stage construction features a specially shaped top reed and a ported bottom reed. The top reed is lightweight and tough for quick throttle response at idle or low RPMs. The stiffer, bottom reed is ported to provide maximum flow and horsepower at higher RPMs.
More Air Flow.
The dual-stage design allows you to replace your stock reed stop with a Rev-Plate which permits the reeds to open freely and function efficiently.
More Air Velocity.
The multi-port feature of the bottom reed creates more channels for the charge, delivering increased velocity to the intake ports.
More Overall Power.
Dual-stage reeds 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.
THE BENEFITS
• Added acceleration allowing you to carve through the waves
• Throttle response that delivers performance with the snap of the throttle
• Improved engine efficiency providing a broader, smoother powerband
• Increased fuel economy
• Longer reed life - Boyesen reeds outlast all other aftermarket reeds
