Boyesen Pro Series Reeds - TRS 250>300 Keihin

A POWERFUL SOLUTION TO A SIMPLE PROBLEM
One reed petal is NOT enough! The reed petals in all 2 stroke machines 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.

THE BOYESEN PRO SERIES REED ADVANTAGE
Boyesen Pro Series Reeds are more responsive than our traditional Power Reeds. The carbon-fiber top reed has an excellent response characteristic that provides even quicker acceleration, stronger throttle response, and more over-rev than our standard Power Reeds. The fiberglass bottom reed provides stability and longer reed life. The Pro Series Reeds are the most potent reed available, delivering improved power, torque and feel like no other after-market reed system on the market.

 
T2 EPOXY
The RC2 Pro Series reeds now feature category-leading toughening additives to increase reed petal lifespan by resisting breakdown from damaging agents found in fuel. All RC2 Series Carbon Tech Reeds contain a proprietary formulation of resin additive that works to create stronger molecular alignment while maintaining the carbon's overall modulus of elasticity.
 
X-CROSS DUAL CARBON WEAVE
All RC2 Pro Series reeds feature the absolute highest quality aerospace grade carbon material interwoven into specific tension combinations that maximize power delivery. Boyesen engineers specifically tune the carbon matrix tension using a proprietary weave formula and special layup techniques that optimize each specific reed tension to work in unision with the engine's unique intake pressure pulses for each make/model/year machine.
 
MS PLUS FLOW OPTIMIZATION
Boyesen's race-proven MS PLUS Optimization uses multi-staged reed petals to distribute the engine?s pulse forces over more surface area. By using a multiple reed petal stack, it is possible to acheive peak horsepower AND durability. The patented multi-stage design incorporates a specially shaped top reed petal and a ported bottom reed petal. The top petal is lightweight and resilient for crisp throttle response at partial throttle or low RPM. The stiffer, bottom petal is ported to provide maximum flow and horsepower at higher RPM.
