Description

Boyesen Power Reeds Yamaha for
REVOLUTIONARY PERFORMANCE

Boyesen’s patented dual-stage design incorporates a specially shaped top reed and a ported bottom reed. The top reed is lightweight and resilient for crisp throttle response at partial throttle or low RPMs. The stiffer, bottom reed is ported to provide maximum flow and horsepower at higher RPMs. More valves equal more power by creating:

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 OF Boyesen Power Reeds Yamaha

  • Quicker acceleration for that all-important hole shot.
  • Crisper throttle response for fast corner exits and surer jumps.
  • More horsepower throughout the powerband for guaranteed performance.
  • Improved engine efficiency and fuel economy for the long-distance rider.
  • Longer life – Boyesen Power Reeds outlast all other aftermarket reeds

POWER REEDS

A POWERFUL SOLUTION TO A SIMPLE PROBLEM

One reed petal is NOT enough! The reed petals in all 2 stroke engines take an incredible amount of abuse! At peak RPM, reed petals are opening and closing hundreds of times per second. Over time, a single reed loses its ability to regulate flow rates in proper proportions. This causes a loss of reed petal reaction and reduces the consistency of peak horsepower. Boyesen’s revolutionary dual-stage reed design delivers more usable power than stock. Stock single-stage reeds operate most effectively within a relatively narrow RPM range and are limited because of the single stage design. Boyesen’s one soft reed on top of one firm flow-through reed gives you a wide range of intake control, plus increased intake velocity. Your original reeds can’t possibly duplicate that performance. 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. The multi-port feature of the bottom reed creates more channels for the charge, delivering increased velocity to the intake ports and generating 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.
