Parts/Kit Overview

The R&D Yamaha GP 1300R Stage 3 Kit was developed to have noticeably increased horsepower and top speed over the Stage 2 Kit. The increased compression ratio over Stage 2 will require the additional fuel the R&D E.F.I. Control Unit delivers, and the R&D Free Flow Exhaust will be necessary to reduce water resonator back pressure. Increased throttle response, acceleration, and top speed are significantly noticed! The Stage 3 Kit produces great horsepower throughout the entire range. The Stage 3 Kit retains great reliability, however, high grade 92 plus pump gasoline should be used exclusively! Extensive testing proved Chevron 92 Techron to be the best overall! Extensive testing of the Stage 3 Kit proved that most would prefer the 13/19 Solas Impeller best overall, however, if itís all about straight line top speed, the Solas 14/20 is the best for top end speed!

  • 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 Ride Plate Trim Pads are redesigned and extended over stock to reduce porpoising while adding top speed performance. Smoother high speed cornering is also significantly enhanced.

  • The R&D Aquavein Intake Grate Kit will substantially reduce cavitation, increase overall handling dramatically and add a 3 to 4 mph average top speed in choppy water conditions!

  • The R&D Pump Shoe Sealer Kit was developed to quickly and easily fill the large casting pockets left in the Yamaha GP 1300Rís pump shoe inlet. Installing the R&D pump shoe sealer kit and resealing the pump shoe will reduce low and high-speed cavitation, which will increase overall handling!

  • The R&D/Solas 13/19 Impeller replaces the O.E.M. 4-blade impeller with a sleeker, better performing 3-blade design! Improved low-end response and increased top speed performance of 1 mph, plus!

  • The R&D Anti-Cavitation Cone was developed to reduce low speed pump cavitation, which will increase acceleration and pump efficiency.

  • The R&D GP 1300R D-Plate was designed to replace the O.E.M. Catalizer system with a simple bolt on part. The R&D Catalizer Removal Plate increases overall performance, allows you to use your choice of oils (many types of PWC oil will harm the O.E.M. catalizer) and increase top speed!

  • The R&D H20 Flow Control Kit assembles on the lower portion of the catalizer housing, and diverts water flow from the water resonator at low speed and RPMís. At high RPMís the adjustable pressure valve opens at peak RPMís to a preferred water pressure and volume amount. The R&D water flow control kit helps make fuel injection control settings easier and more precise for tuning, and will deliver cleaner and snappier throttle response, which will produce quicker acceleration, and stronger mid range power

  • The R&D GP 1300R 45cc Pro Series Precision Cast Aluminum Cylinder Heads are the best way to boost compression ratios economically! Dyno test results have proven that cast heads have less detonation than expensive billet aluminum heads! The R&D cast cyinder heads are girdle kit optional! GP 1300R Girdle Kit Part # 412-12000

  • R&D GP 1300R Free Flow Exhaust is a required kit with higher horsepower output engine kits! Reduces water resonator back pressure and heat! Adds a great performance sound.

  • 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 and up kits. Dyno and water testing have confirmed a significant boost in low-end power on all kits.

  • The R&D H20 Flow Control Kit assembles on the lower portion of the catalizer housing, and diverts water flow from the water resonator at low speed and RPMís. At high RPMís the adjustable pressure valve opens at peak RPMís to a preferred water pressure and volume amount. The R&D water flow control kit helps make fuel injection control settings easier and more precise for tuning, and will deliver cleaner and snappier throttle response, which will produce quicker acceleration, and stronger mid range power.

  • The R&D GP 1300R Power Plenum Air Filter is the largest volume air filter kit available for a GP 1300R engine. R&Dís massive zero restriction plenum design will add to low and mid-range power, and adds a great high performance tone or sound.

  • The R&D GP 1300R M-16Reed Valve Kit will add a significant increase in low-end horsepower between 2000 and 6000 RPMs, 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. manifoldís 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 Systemís technology is backed by 4 National and 5 World Championships in the Pro 1200 Superstock class.

  • 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 GP 1300R VTS/Automatic 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!

  • The R&D/Solas 14/20 Concord Impeller option will produce the fastest top speeds over any other impeller. NOTE: Softer low end response and acceleration will be noticed compared to the Solas 13/19 Concord.

  • The R&D Pro Action Steering System becomes a necessary accessory for many recreational riders and racers! The system is much more precision and stronger than O.E.M., and allows for any Fly, Renthal, etc. pro taper fat bar kits!

NOTE: To properly install the R&D Ride Plate, or the Solas 13/19 Impeller, it will be necessary to install the R&D 87mm GP Series Venturi Nozzle. Part # 162-13587

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 # 802-12001

NOTE: The O.E.M. power valves are manufactured from a cast aluminum material and are notorious for shearing or breaking after 40-50 hours, creating costly engine damage! R&D manufactures a redesigned 6061-T6 Billet aluminum power valve, and power valve lifter arm kit that adds low-end power, and assurance against breakage! Part # 332-13000

NOTE: The R&D Anti-Cavitation cone will reduce overall pump cavitation, which will create greater low and mid-range pump thrust, which increases acceleration. Fine tuning to the steering nozzle angle adjustment can be done by lowering the steering nozzle angle by one degree down from the standard 90 degree (straight) position. This will help keep the GPR driving forward and flat under hard acceleration.

NOTE: With the R&D M-16 Reed Valve System it is recommended to use the Solas 14/20 Concord Impeller or higher degree impeller to reduce cavitation and stay under the low ceiling (7500 rpm) O.E.M. rev limiter setting. R&D Performance is currently developing an ignition system for the GP 1300R, which will allow adjustable rev limiter settings, and high performance ignition map tuning.

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

NOTE: For a full ten plus horsepower gain across the entire RPM range with an incredible boost in low end acceleration and performance, update the 03-04 GP1300R with the 2005 GP1300R header pipe section and R&D Exhaust Power Sleeve! More horsepower with reduced detonation! The 2005 Yamaha GP1300R O.E.M. header pipe section is part # 60T-14712-10-94. The R&D 2005 Yamaha GP1300R Exhaust Power Sleeve is part # 332-13000.

NOTE: For improved pump hook up and top speed performance gains, update the 2003/2004 GP1300R to 2005 GP1300R parts and specifications! Install the new 2005 Yamaha GP1300R Large Hub (75 mm) Pump along with the new R&D Solas 14/20 Dynafly Impeller and R&D Anti-Cavitation Cone! Yamahaís new large hub pump part #6B6-51315-00-94.
