    97 GP Riva ride plate

    The Riva long plate i scored on eBay was new in the package and came with washers to shim the rear of the plate only as stated in the instructions,i placed the plate on the ski and noticed the plate does not meet the intake grate at the front of the plate like the stock one does,what i mean is it is not level the plate seems to be thinner so if a straight edge is placed on intake grate and ride plate there is probably 1/4 " difference,ride plate being closer to hull,maybe i am wrong but should that be level and then you shim the back of the ride plate for tuning?if so then i would have to shim the front to make it level and then use more than the normal amount of washers for the rear. the stock long plate is perfectly level with the intake grate.maybe i will just try it and see what happens.

    If you want speed....washers up front until it's just a mm or so higher then the intake grate. If you add washers in the back, it helps reduce bounce...but costs big time speed.

    Like they said shim under the front of the plate not the back.

    Nice to hear her come to life
    The stock plate in not bad but you can only shim it a little bit in front or it hangs down below the grate.
    Sounds like you have a 1/4" with the riva plate.
    If you shim the front down but leave it above the grate you should feel some porpouse at about 35mph but only if you try and cruise at that speed.If you grab some throttle and go straight to speed you eliminate that problem.
    My ride plate on my 99 is just barely above the grate it gets the nose up in the air and reduces drag = more speed on the gps..............

    Thanks for the info,i am a speed demon,after i have a ski for awhile it is never fast enough,i guess that is normal,but the 1200 is the biggest i have had so far,I have not taken to the lake ,as i just got it running today,just trying to do some homework to get more speed and eliminate issues ahead of time.
