Intake Manifold Kit For A 2009 kawasaki 800 SX-R

A POWERFUL SOLUTION TO A SIMPLE PROBLEM

Designed for 2009 kawasaki 800 SX-R, this Boyesen component is built to support dependable fitment, durability, and reliable performance for serious riders.

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.

THE BOYESEN POWER REED ADVANTAGE

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.

T2 EPOXY

The RC2 Series Power Reeds now features category-leading toughening additives to increase reed petal lifespan by resisting breakdown from damaging agents found in fuel. All RC2 Series Power Reeds contain a proprietary formulation of resin additive that works to create stronger molecular alignment while maintaining the material's overall modulus of elasticity.

MS PLUS FLOW OPTIMIZATION

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. By using a multiple reed petal stack, it is possible to acheive peak horsepower, more torque, improved stall resistance and greater overall reed durability.

FREE REVING POWER

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. This results in a free reving, yet extremely smooth power delivery with an improved connection between your hand, the rear wheel and the terrain.
