High Volume Fuel Pump (265L p/Hr) Yamaha 6S5 R&D Pro Tune Adjustable Cam Gear Kit - Yamaha FZS/FZR/SHO
Our Price: $209.95
Our Price: $219.95
High Volume Fuel Pump (265L p/Hr) Yamaha 6S5 R&D Pro Tune Adjustable Cam Gear Kit - Yamaha FZS/FZR/SHO
This is a direct replacement high volume fuel pump for high performance applications. Delivers 265LPH to support highly modified engine packages. Easy installation requires no modifications. Includes detailed installation instructions. R&D’s Racing Cam Gear kit allows a huge boost in overall horsepower to be gained by custom tuning the OEM Camshafts LSA (lobe separation angle) set up. Tuning the OEM Cam’s LSA with R&D Pro Tune Cam Gears can add 200-300 RPM’s, increased boost pressure, and 2-3 MPH to your existing engine package.  Adjusting the camshafts LSA is a very simple “BOLT IN” modification with the R&D Pro Tune Adjustable Cam Gear Kit.  Understanding the LSA concept principle is fairly easy.  A wide LSA like found in the SHO and FZR will generally result in decreased valve overlap, later intake events, earlier exhaust events, and high intake manifold VACUUM (higher vacuum at idle) which produce great idle, smooth accelerating with mild low and top end power.  Wide LSA’s are great for school buses and soccer mom vans.  However, if strong mid range pull and top end horsepower is what you’re looking for, then a narrower LSA will need to be generated. The R&D Pro Tune Cam Gear Kit allows the LSA (lobe separation angle) to be adjusted narrower which will generate increased valve overlap, earlier intake events, and later exhaust events.  Resulting in snappier throttle response, increased mid range and top end power with more boost.  Why spend big money on aftermarket camshaft kits (i.e. 1800 N.A. Cams) that generally only offer a narrower LSA?  Buy the R&D Pro Tune Cam Gears designed specifically to offer a narrower LSA to improve overall power at a fraction of the cost of aftermarket cams, and they provide an optimum overall tune with the stock or reprogrammed ECU.  
The R&D Pro Tune Cam Gears are billet CNC machined, Heat Treated, and ground from steel alloy to deliver durable strength with precise timing.  The R&D Cam Gear Kit offers four possible LSA combinations that allow the cams to be precision tuned depending on the type of riding or racing and type of fuel.  The R&D Cam Gear Kit utilizes the proven and precision O.E.M. shouldered bolt mount design to perfectly center, align, and time the cam and properly support the cast cam flanges from cracking and breaking over slotted gears that are known to break cam flanges. R&D knows that cam lobe profile and cam timing is the heart of a good running engine, In fact, R&D has built a specific engine designated for degreeing, checking and proving camshaft lobe specifications, LSA and LC combinations. Depend on the Pro’s at R&D to deliver all your horsepower needs.

    RD Surge Protector Kit for SHO FZR Upgraded Yamaha Supercharger Clutch Assembly
    R&D announces the release of the new R&D/Tial 50mm Surge Protector Kit. R&D has been committed to on going research for any part that proves to be an aid in reducing the inherent and well known clutch issues related to running high performance boost wheels and high boost pressures in the Yamaha 1.8 Supercharged engine. R&D has noticed a significant reduction in clutch related issues in high boost ranges by ???Going Big???.  R&D engineers have concluded through endurance testing that the new 50mm R&D/Tial Valve with its huge 50mm lightweight billet aluminum piston, and 6 massive (bigger than any other valve) pressure relief ports, to outperform the smaller (25-35mm) HKS Sequential, and 35mm Greddy RZ Valves. The trick R&D has found with this valve is, in aggressive off throttle situations with a gear driven supercharger the big Tial 50mm piston responds quickly to allow the reduction of boost pressure which relieves back pressure that can affect the clutch. The new 50mm design also has a much larger diaphragm over HKS and Greddy, which helps the piston react quicker to relieve pressure. If you are running Boost Wheels that produce over 15 pounds of boost, R&D strongly suggests looking into a larger valve setup. It only stands to reason that with higher boost pressures, a larger valve can allow quicker discharge of air volume. Valve kit comes complete with R&D high temp silicone hose, Tial 50mm valve, billet Aluminum V-clamp, banjo style vacuum fitting, and ????? vacuum line.
