    Shimming rear of riva plate down.

    Anyone tried shimming the rear of the riva plate down? I want my standard rough water hook up back. I tried it with the R&D top loader, hook up was good but I lost 2 mph which took me back to slower than standard. Had the best of 69.2 stock with a average of high 68s, 67.4 with plate and grate (slow getting there), back to 68s 69s with just plate but lacking rough water hook up. I see it as a challenge now to make this plate work.

    If you have a wedge try flipping it with the plate and let us know what happens.

    I found the Riva plate quite annoying, it totally destroys the rough water capability of the 250, sure you get 2mph on perfect glass, add a bit of chop and forget about it. I can certainly see how a LX could pass a Riva plated 250. As for shimming, I was thinking along the same lines but figured you would lose any gains the plate gave you in the first place i'm going back to stock for now and although I don't care for their products, i'll wait and see what R&D comes out with..

    What this ski really needs is adjustable trim..

    How about a auto drop nozzle?

    R&D will have a modified stock steering nozzle that allows for Auto Drop nozzle operations. I would think it would be more beneficial to CC racing.. IMO

    Hi Skip, I do a bit of cc racing and a lot recreational riding, I'm always looking for the perfect setup for all types of riding which is hard. I seemed to lose a lot of speed with the R&D top loader, more than you did in your report and yet didn't gain much if anything with just the riva plate over stock. I'm starting to wonder if something else was playing up on the day. I plan to do a lot more testing this weekend. Have you ever had the motor die on a hard left hand corner on a cc? mine was doing it with 3 bars of gas left, I'm running a R&D low fuel pickup. Any help would be much appreciated. Thanks

    you will see higher speeds with the shaved ride plate - one of our offshore crew has one - only moderate hookup / speed loss in the chop.

    I will buy R&D's setup when produced, sounds promising.

    Looks like I will have to try a R&D plate to.
