Kawasaki 650 Boyesen Power Valve Reeds
- Fits all Kawasaki 650 engines
THE GATEKEEPERS OF POWER
> 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.
Boyesen has taken its years of experience in reed technology and developed a line of watercraft reeds that provide you with impressive performance gains, whether you want to be the fastest one on the water or are looking for a more enjoyable ride.
Single Stage Reeds VS Dual Stage Reeds ::
The stock, single-stage reeds in your watercraft are limited in their ability to function efficiently. A thin, flexible reed will perform well at low RPMs, but does not perform well at mid to high RPMs. A thicker, stiffer reed will perform well at high RPMs but not at low to mid RPMs. Therefore, one reed of a given thickness and stiffness is not versatile enough to perform effectively throughout the powerband. The result being that watercraft manufacturers end up compromising on a reed of a given thickness and stiffness that will provide adequate response.
In order to overcome these limitations, Boyesen developed and patented the dual-stage reed. A highly responsive, flexible reed is placed on top of a stiffer, ported reed for superior performance throughout the entire powerband. The advanced dual-stage design incorporates a specially shaped top reed that is lightweight and resilient for crisp throttle response at partial throttle or low RPMs. The stiffer, bottom reed is ported to provide your engine with maximum flow and horsepower at higher RPMs. 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 as you accelerate or back off the throttle. This translates into a dramatic increase in engine efficiency and performance across the entire powerband, from start-up to wide open throttle.
A More Enjoyable Ride
Why bother with poor or erratic acceleration at partial throttle? Is your engine loading up while idling through no wake zones? Are you frustrated by boggy, lifeless throttle response? Make your time on the water more enjoyable! This is what you can expect from Boyesen Power Reeds:
> Easy starting and smoother idling for those no wake zones
> Instantaneous acceleration allowing you to carve through the waves
> Throttle response that delivers performance with a snap of the throttle
> Crisper midrange to pull that extra boat length
> Improved engine efficiency providing a broader, smoother powerband
> Increased fuel economy
> Longer reed life - Boyesen Reeds outlast all other aftermarket reeds
> Performance that delivers a more satisfying ride
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.
