Heat Is the #1 Enemy of 4-Stroke Engine Performance Boyesen SuperCooler Water Pump Cover and Impeller Kits are specifically designed to enhance the performance of your engines 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. 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. Boyesens 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. Win the War on Heat, Bolt on a SuperCooler NOW! 2-piece cast aluminum construction. Oil filter access for hassle-free filter changes. Increased coolant flow at all RPM ranges. Patented Nautilus style impeller for hydrodynamic efficiency. Note: Gasket(s) is NOT included; use stock piece(s) or purchase new one separately. Feature details: Casting: By casting a totally new water pump cover, Boyesen was able to maximize the flow through the unit. Boyesens design takes advantage of everything from Bernoullis Effect to biological studies. Superior Internal Hydrodynamic Shaping: Stock water pumps arent 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. Boyesens Nautilus-shaped cover and impeller increase pump capacity. Optimized Water Inlet Diameter (High Cooling Capactiy): Unlike the stocker, Boyesens 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). Optimized Impeller (Patented Nautilus-Style Impeller): Boyesens patented impeller design is 25 percent more efficient at moving water than the inefficient stocker.

FMF Factory 4.1 titanium muffler combined with the titanium Megabomb head pipe unleashes your motorcycles full potential with massive power increase and substantial weight savings. The combining technologies of the Factory 4.1 muffler and the Megabomb header have been developed to compliment each other's power characteristics to provide a complete exhaust system that builds power over the entire range. FMF Factory 4.1 Muffler The FMF Factory 4.1 slip-on exhaust is the same exhaust that professional racers use to bring home championships around the world. FMF constructed the Factory 4.1 slip-on exhaust to offer the lightest weight titanium slip-on on the market. The titanium FMF uses on this exhaust is superior in quality and comes directly from the USA. The technology in the FMF Factory 4.1 slip-on exhaust cannot be found in any other exhaust on the market. FMF developed the proprietary Chamber Core. This FMF original core technology allows for smoother and more efficient exhaust flow to maximize the power output. FMF developed the Factory 4.1 slip-on exhaust to be used for competition and this pipe is ready to take to the track straight out of the box with the AMA stamp of approval for meeting their sound requirements on most motorcycle models. The FMF Factory 4.1 has been designed to allow for easy maintenance with a removable sleeve for repacking. FMF offers the ability to fine tune the performance of the Factory 4.1 exhaust with the addition of tuning inserts and the option of a spark arrestor to give you no boundaries. FMF Titanium Megabomb Header The FMF Megabomb header is yet another testament to the continued dedication of FMF to developing the best performing motorcycle exhaust components. The FMF Megabomb header is designed with a unique midsection, comparable to the Powerbomb header, that provides improved power across the power range. The unique design of the Megabomb header allows for better low end torque similar to a long header while also improving top end power much like a short header. Although the FMF Megabomb header offers the advantages of a long header, the design of the Megabomb header reduces the length and the chances of getting in the way of damage. The larger midsection of the FMF Megabomb header creates a larger surface area for sound dissipation to reduce the sound output by as much as 1.5dbs. FMF constructed the Megabomb header out of their exclusive Ti-Metal for an extreme weight savings with added durability.

Ride Engineering keeps your dirt bike running straight and your chain tight with their trick axle blocks. The Ride Engineering Axle Blocks are constructed out of Billet aluminum for lightweight durability. Coming in at 6 mm longer then stock reduces your dirt bike from "rocking" by keeping the chain adjustment bolts less extended. Ride Engineering includes two M8 hex nuts to double lock your dirt bikes adjusting nuts, keeping them nice and snug. Finishing off the axle blocks with durable anodizing puts a little flash to your swing arm. Sold as a pair.
