BOYESEN Power Reeds Kawasaki KX 250

<HTML><HEAD></HEAD> <BODY> <P>ATHENA is the sole distributor of Boyesen products all over Europe. Boyesen is the worldwide leader for carbon / fibreglass reed valves</P> <H3>REVOLUTIONARY PERFORMANCE </H3> <P>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:</P> <UL> <LI>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. <LI>More Air Velocity. The multi-port feature of the bottom reed creates more channels for the charge, delivering increased velocity to the intake ports. <LI>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.</LI></UL> <H3>THE BENEFITS</H3> <UL> <LI>FASTER STARTS: No more sitting and cranking cranking when engine is cold or hot <LI>SMOOTHER IDLE: No more coughing, sputtering and dying. <LI>Blazing acceleration for that all-important holeshot. <LI>More horsepower throughout the powerband for guaranteed performance. <LI>Smoother Trolling: Troll down to a heartbeat with the controll of Boyesen Power Reeds <LI>Improved engine efficiency and fuel economy. Up to a 10% increase <LI>Longer Service life - Boyesen Power Reeds outlast all other aftermarket reeds.<BR></LI></UL></BODY></HTML>

BOYESEN Water pump kit Yamaha YZ/WR 250 F

<HTML><HEAD></HEAD> <BODY> <H2>Boyesen SuperCooler Water Pump Cover. Your ultimate weapon against heat!</H2> <P>Boyesen SuperCooler Water Pump Cover and Impeller Kits are specifically designed to enhance the performance of your engine's cooling system. These high-flow, hydrodynamic water pump kits have been tested and designed to flow more coolant. By increasing the flow, the engine will run cooler at a more constant temperature.</P> <P>The Boyesen Supercooler can reduce engine temperatures by as much as ten degrees, as confirmed by tests at Team Kawasaki. How does the Supercooler achieve this? Hydrodynamics. Boyesen's investment-cast aluminum water pump cover has bigger water inlets, a sculpted design, no casting seams, less restrictive corners, a more efficient impeller and less cavitation.</P> <H2>Features</H2> <P>2-piece cast aluminum construction.<BR>Oil filter access for hassle-free filter changes.<BR>Increased coolant flow at all RPM ranges.<BR>Patented Nautilus style impeller for hydrodynamic efficiency.<BR>Note: Gasket(s) is NOT included; use stock piece(s) or purchase new one separately.</P> <H3><BR>Feature details:</H3> <P>Casting: By casting a totally new water pump cover, Boyesen was able to maximize the flow through the unit. Boyesen's design takes advantage of everything from Bernoulli's Effect to biological studies.<BR>Superior Internal Hydrodynamic Shaping: Stock water pumps aren't very hydrodynamic. Their internal shape and impeller create excessive amounts of air bubbles in the water. Air bubbles lessen not only water flow, but the amount of water per cubic gallon. Boyesen's Nautilus-shaped cover and impeller increase pump capacity.<BR>Optimized Water Inlet Diameter (High Cooling Capactiy): Unlike the stocker, Boyesen's water inlet has an increasing diameter and artfully curved shape. This is a vast improvement over most stock inlets, which decrease in diameter as they near the impeller and have a 90-degree bend at the pump (a very serious hydrodynamic no-no).<BR>Optimized Impeller (Patented Nautilus-Style Impeller): Boyesen's patented impeller design is 25 percent more efficient at moving water than the inefficient stocker.<BR></P> <P></P></BODY></HTML>
