The R&D GP 1300R Ride Plate is extended and re-angled over stock to reduce porpoising while adding top speed. The R&D GP 1300R Ride Plate is the only aftermarket design to dominate in Offshore, National, and World Championships, and to be used and endorsed by Factory Yamaha racing teams for 5 years!

The R&D Aquavein Intake Grate Kit will substantially reduce impeller/pump cavitation, dramatically increases overall handling, and adds a 3 to 4 mph average top speed in choppy water conditions by keeping the pump loaded and hooked up!

The R&D GP 1300R Pro Series Sponson Kit incorporates an industry first, 15 position adjustable design, which will allow more precision blade and backing plate adjustments. The best sponson kit available for a GP 1300R.

The R&D 2005 GP 1300R High Performance Pro Series Cylinder Head Kit was developed to raise each cylinders compression ratio to a safe level with more power and increased RPMs. R&D cast aluminum heads run safely and detonation free on 91-92-octane pump gasoline. The R&D Pro Series heads are girdle kit optional. Part # 412-13000.

The R&D GP 1300R E.F.I. Fuel Control Unit was developed to deliver increased fuel volume to areas in the fuel map where lean conditions exist. The E.F.I. fuel control unit is mandatory on Stage 2 kits. Dyno and water testing have confirmed a significant boost in low-end power on Stage 3 kits.

The R&D GP 1300R Power Stack Air Filter Kit is designed to assemble on to the front of the O.E.M. air plenum box. The R&D Power Stack adds bottom and mid range power performance while increasing engine RPM’s.

The R&D GP 1300R M-16 Reed Valve Kit will add a significant increase in low-end horsepower between 2000 and 6000 RPM’s, as well as boost the peak horsepower range. The R&D M-16 Reed System incorporates a completely redesigned billet intake manifold, which alleviates the O.E.M. manifold’s crossover design, which can add an increase of 100 peak RPMs. No other reed valve or intake system produces more horsepower gains, or is more reliable. The R&D M-16 Reed Valve System’s technology is backed by 4 National and 5 World Championships in the Pro 1200 Superstock class.

R&D GP 1300R Free Flow Exhaust Kit is required with higher horsepower output engine kit packages! The Free Flow Kit reduces water resonator back pressure and heat, which will reduce detonation! The R&D Free Flow Exhaust Kit features a new water volume flow control gasket that will reduce the excessive amount of water flowing into the resonator box. The Free Flow Kit will deliver instant throttle response and help make low and mid-range fuel controller settings much more defined and precise! Adds a great performance sound.

The R&D GP 1300R VTS/ Automatic Trim Drop Nozzle System is completely adjustable to suit any type of riding style or conditions. The system offers an adjustable automatic nozzle drop for smooth cornering, and allows the O.E.M. VTS (quick shift) to be used to adjust nozzle positions in the O.E.M. 5 degree increments while straight line riding! This is an industry first and a must have part for a GP 1300R!

NOTE: To properly install the R&D Ride Plate, or use the Solas 14/20 Dynafly Impeller, it will be necessary to install the R&D 87 mm 1300R Series Venturi Nozzle. Part # 162-13587. If the R&D 87 mm Venturi Nozzle is not used with the new Solas 14/20 Dynafly the result will be a much lower RPM and peak speed than posted. A box stock ‘05 GP 1300R with a Solas 14/20 Dynafly will have an RPM reading of approximately 6850.

NOTE: Higher performing engines, and/or heavily carboned exhaust systems put out more exhaust heat, which may cause the O.E.M. Cat overheat warning sensor to activate prematurely. To deactivate the Cat overheat sensor, install the R&D Cat sensor chip. Part # 802-13001.

NOTE: The 2005 GP 1300R engine platform does not have a Y.P.V.S. Power Valves system unlike the 2003 and 2004 Yamaha GP 1300’s. To achieve low end acceleration and mid range power performance noticed on 2003-2004 GP 1300R’s, R&D suggests the addition of the R&D Fuel Injection Fuel Controller!

NOTE: The O.E.M. cylinder head produces 120-125 P.S.I. of static cranking compression. The new R&D High Performance Pro Series Head Kit will raise the static cranking compression to a 91-Octane pump gasoline safe 145-150 P.S.I.

NOTE: R&D offers a high performance cooling kit for the GP 1300R, which will add an additional 1/2 inch water line. The R&D cooling kit comes complete with a billet aluminum cooling strainer block, precut water line, brass fittings, through hull fitting, weld mount fitting, and clamps. The R&D high performance cooling kit is a great addition to any level of performance package, and will help keep the GPR engine temperatures down to safe levels producing better overall performance and adding reliability! Part # 660-12000.
