Boyesen Reeds

Boyesen Power Reed

Boyesen Power Reeds

THE GATEKEEPERS OF POWER
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 equals 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.
> Secondary Reed
(Top Reed)

The top reed is specially shaped, lightweight and resilient for crisp throttle response at partial throttle or low RPMs.
> Primary Reed
(Bottom Reed)

The bottom reed is thicker, stiffer and ported to provide stability, maximum flow and horsepower at high RPMs.
> Rev-Plate
Allows the reed to open unimpeded and function more efficiently at higher RPMs.

THE BENEFITS

• Quicker acceleration for that all-important holeshot.
• 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.

QUALITY AND CRAFTSMANSHIP
Since 1972, Boyesen has maintained its position as the leader inreed induction technology by introducing dozens of breakthroughs and refinements in reed performance. The latest advances in material technology are incorporated into every reed design, allowing us to manufacture reeds that not only increase power, but are durable and dependable too.


MATERIALS
From beginning to end, Boyesen supervises every aspect of the manufacturing process for our reed materials. The threadcount of the fiberglass or carbon fiber, the positioning of the plies, and the type of epoxies used to fabricate the reed materials are specified by Boyesen to insure reed materials of uncompromising quality. Multiple plies are then laminated in variety of configurations to obtain reed materials of varying functionality. More than fifty individual types of reed material are fabricated for a variety of applications.

All reed materials undergo a rigorous three-step quality control inspection. Each sheet of material is examined and tested for manufacturing flaws. The material is then cut into individual strips which are measured with a digital micrometer to insure proper thickness. After the reeds are stamped, they are individually hand inspected. We spare no effort in assuring our customers that only reeds of superior quality are packaged and sold.

DESIGN
Careful consideration is taken with every reed design. Variables such as engine and carburetor size, operating characteristics of the engine and computer-aided flow analysis of the reed block are used to determine the optimum configuration for each reed design. Intial design protoypes are cut on a computerized, three-axis machining center, allowing for quick and accurate designs. Further testing and analysis is then done on our SuperFlow flow benches and SuperFlow 901 and Dynojet 150 dynamometers. Finally, every design is tested in the field by a variety of industry specialists to insure that the each new design provides maximum performance and life.

GUARANTEED
Every Boyesen product comes with a money back guarantee. If you are not completely satisfied with a product, return it for a full refund.
