The EJSBA Board of Directors have decided to re-assess the rules that were sent out in JSN# 6. Here are the new rules. Ski Stock: The maximum capacity for two stroke engines is 1100 cc, but they must stay within the Power-Weight ratio decided in December 07: 1.52. This Power-Weight ratio is based on the HSR-Benelli S4 already admitted in the Stock class for 2006 & 2007. Note: this capacity of 1100 cc must be OEM, you can use only OEM pistons and the stroke must stay OEM. In the case of the new Ski produced by Zapata, the Power-Weight ratio must be 1.52 like any other Ski already homologated in the Ski Stock Class. Zapata must put his engine on a homologated Dyno to prove that this Ski is within the Power-Weight ratio restraints, this must happen in the presence of a member of the Board of Directors. The lowering of power or rising of weight must only be done by the manufacture. A production of 100 units is required to be homologated for the Stock Class. The same rules apply to the new HSR-Benelli S8 Pro Edition; the Power-Weight ratio must be 1.52 set by the manufacture. So far HSR aren’t prepared to change the Power-Weight ratio of the S8 Pro Edition. De facto this Ski will not be homologated in Stock Class. Ski Limited: No changes, only to the capacity of two strokes, which now raise up to 1100 cc. Note: the capacity is theoretical and cannot be reached by changing the sleeves or the stroke of the OEM engine. Hard Chrome cylinders or Nicasil cylinders must be kept to the original bore size of the OEM cylinder. The Zapata Ski will be admitted in the Limited Class with a maximum of 138 BHP as long as it reaches the required units (100) to be homologated in the Stock class. The HSR-Benelli 142 BHP version will be admitted into Limited Class, but because this Ski will not meet the Power to Weight ratio for Ski Stock Class, a production of 100 units is needed before it qualifies to race in Ski Limited. Ski GP: No changes, only that the cubic capacity rise-up to 1100 cc for two Strokes. The EJSBA Board of Directors understands that not everyone will agree with these rules. But we feel that the majority of riders will be satisfied with this outcome. See you at the 2008 European Championship.

From the pioneer years up to the golden days of the sport and from two stroke decades to the four stroke era the R&D Company was present, supporting the sport and the market with high quality products, immaculate service and unique performance.

The R&D RXP-X Auto Trim Kit was developed to override the OEM VTS System with a fully adjustable and fully automatic trim system! The R&D Auto Trim automatically drops a rider preferred adjustable 2-8 degrees. Drive from turn to turn never worrying whether the trim is in the best position for perfect turn negotiation! The R&D Auto Trim allows you to set the trim up your way to carve perfect turns every time! For long straight rides install the R&D VTS/Holeshot Driver Rod (Pt. # 163-21503), which works in conjunction with the R&D Auto Trim to electronically override the Auto Trim back to the OEM VTS Nozzle angle trim settings! The combination allows the best of both worlds for recreational and closed course riding!

The R&D RXP-X Anti-Cavitation Pump Cone Kit will reduce overall internal pump cavitation within the Sea-Doo’s offset reduction/compression nozzle design. The O.E.M. reduction/compression nozzle is offset, while the O.E.M. pump cone/bearing cap remains straight which causes uneven pressures within the pump and reduction nozzle. The R&D Anti-Cavitation Pump Cone is offset and reshaped to match the O.E.M. reduction nozzle offset promoting even pressures, which will substantially reduce cavitation, increase pump hook up, boost acceleration, and increase top speed performance.

The new R&D SEA-DOO Pro Series Sponson Kit was designed and developed to deliver lots of handling performance with adjustability options, which allows you to setup your SEA-DOO “your way” with 2-position backing plate and 3-position sponson blade adjustability. The R&D Pro Series Sponson Kits have been extensively offshore, race track, 1 up recreational, and 2 up recreational tested to guarantee a comfortable setting for any riding style! The R&D Sponson Kit will deliver a much smoother and more predictable ride over OEM sponsons. Low speed and high-speed turns are a breeze with new found control! There is also a higher end recreational/race setting with enough grip for the best of pro’s! Track tested with Nicholas Rius and Chris Fischetti. With plenty of adjustability, it’s the only sponson kit you will ever need.

The R&D 2.5 Degree Reduction Nozzle Wedge Kit for the new Sea-Doo RXP-X has been designed, developed and tested extensively in all types of flat and rough water conditions to ensure that there would be no compromises any where in the Sea-Doo RXP-X’s handling performance. Extensive testing has led R&D development team to wedge the reduction nozzle up 2.5 degrees, which will inexpensively give the Sea-Doo RXP-X better handling everywhere and provide a boost of up to 1 mph in top speed performance. In fact, a much smoother and more predictable ride will be noticed, along with the reduction of annoying bow spray. The billet aluminum CNC machined 2.5 degree reduction nozzle wedge kit was specifically designed to work with the OEM O.P.A.S. and Sea-Doo VTS systems. The R&D Sea-Doo RXP-X Pump Wedge Kit comes complete with the necessary adjustable billet VTS trim rod and billet steering cable extender. A smoother, more enjoyable, dryer, faster ride only from R&D.
