The R&D RC1 Recreational Camshaft Grind Specifications have been extensively endurance tested to be the best lobe profile for recreational riding or offshore racing. The lift and duration are similar to the Yamaha 1800 N.A. cam with a total lift average of .368”. The duration on the RC1 cam is less at .050” lift over the N.A., however, the same 6° degree duration advantage is in the recipe. That puts the RC1 comparable on lift, equal on overall duration and a strong low end vacuum to allow the use of R1, R2, and R3 ECU’s. R&D has worked hard in the duration curve area of the cam paying careful attention to the duration at .050” and overall added duration.

The R&D RC2 Racing Camshaft Grind Specifications have been Race Proven during the 2009 and 2010 racing seasons. No other camshaft has more lift and more duration than the RC2. The nearest competitor to date is the Yamaha 1800 N.A. Cam with a total lift average of .368”. That puts the RC2 a full .020” higher. R&D has worked hard in the duration curve area of the cam paying careful attention to the duration at .050” and overall added duration. R&D is currently working on the RC3 Racing Cam available in mid October. The R&D RC2 camshaft kit is a performance modification that is performed in a normal 2-3 day turnaround to your existing camshaft cores. R&D also stocks Camshaft kits that can be mail ordered direct with a reasonable additional cam core charge. R&D suggests that the FZ/FZR, and SHO supercharged engines should benefit greatly from a supercharger or turbocharger specific cam lobe profile design and custom LC and LSA set up.

The pictured Intercooler core is made by aluminum and it has been welded on top and bottom (i.e. not a press fit). It has been tested to pressure of 100psi and is leak proof. The particular core has been designed as a heavy duty substitute of the OEM one therefore it does not alter the AFR. It is a bolt on unit that increases the overall reliability of the Kawasaki powerplant. It is manufactured in Cyprus under the specifications of Christos Efthymiou, owner of Aquabike Worx and costs 650euro (excluding shipping costs).

This is the illustration of the first radial reed valves that have been patented in the USA recently. Until this moment we have not received yet further information regarding the materials that have been used for this construction but certainly are something radical. We hope that soon the company will provide us with further information as well as some technical specification.

The new Monster Wheel is already featured on the news section but this is a very important additional information provided by R&D. The key Features of the new Monster wheel are: Aggressive throttle response, increased horsepower, Increased boost pressure ( 10 P.S.I. over stock @ 8500 rpm) Increased airflow volume ( 4.5-5 pound per minute gain), 100+ horsepower increase (with R&D R3 ECU), 325+ horsepower using aftermarket ECU, Precision balanced (turbo specs .012-.027 gram inches), Utilizes O.E.M. Reprogrammed R3 ECU ignition system, Utilizes O.E.M. fuel injectors w/R&D RRFPR, R3, and Powershot 91 octane pump gas friendly with R3 ECU, and Easy installation. C5 Modification Requirements: R&D High Performance Pro Series Intercooler Kit w/R&D Greddy BOV, R&D Rising Rate Fuel Pressure Regulator Kit, R&D R3 ECU upgrade to allow 8500-8850rpm, R&D Powershot, R&D engine/intercooler Cooling Kit, R&D Twin Prop. NOTE: The C5 Monster Wheel will work best in sea level to 2000 ft. elevations, or in ambient air temperatures between 60 and 100 degrees. NOTE: The C5 Monster Wheel Kit will require serious impellor upgrades; call R&D for the latest in impellor suggestions. Contact R&D for intercooler suggestions, and impellor pitch/nozzle combination that will be best for your performance level or application. R&D stocks the largest selection of custom impellors for the SHO/FZ/FZR.

Solas impellers for Yamaha SuperJet ‘96-07 and SuperJet ‘08-10. The point is that the pump of 08-10 Super Jet is same pump as 96-07 Super Jet. Some owners wonder Why Solas made new Impeller YQ Series for 08-10 Super Jet? The answer is: Yes, they run the same pump but it is set back further and uses the Raider trim system on it. The YB-CD impellers will work but it has a smaller inner hub than the 2008 up O.E. impeller and doesn’t work as efficient as the YQ impeller which also has the larger inner hub. On the picture, left is YQ impeller and right is YB Impeller.

Ultra’s Intercoolers are made for a specific use and have been tested intensively by Kawasaki R&D engineers. They core is a press fit unit on the case though after 35-40hours it starts leaking. At least this is the case on some units that were used in Stock Class racing. The point is that an official dealer and service of Kawasaki Jet Ski has informed us that Kawasaki Intercoolers do not show such signs of leakage. The point is that this particular leakage was not shown on standard units and only to ones that there were used with different cooling system (updated or modified) or under race conditions.
