    Wanting to start modding my GPR, and have some questions.

    I want to start modding my GPR to get some more top speed and acceleration. I have been looking into a ride plate(jim's, riva) as my first mod. Is this a good idea for a first mod? Also will an aftermarket plate change the characteistics of the ride and handling, and finally, will it be better in rough AND smooth water?


    THanx.

    GPR Mods to do first

    Welcome to the forum !

    Do you have a GP1200R or GP1300R ?

    I would add an aftermarket ride plate and have it modified.
    Jim's Performance and Island Racing both sell aftermarket modified rideplates.

    Also, use our search feature for additional help or just plain ask

    Ok, so which ride plate would you guys recommend for best "out of the hole" acceleration", maximum top speed on glass and rough water, and preferably does not change the handling of the boat.

    Thanx

    So I;ve pretty much decided to put on a 1200 intake grate, jims plate, and the jetworks mod as my perormance mods for now. Two questions tho, are the RIVA performance pump cone, pump seal kit, and free flow exaust worth the hassle, and money, and does Jim's Plate change the handling of the boat, or just acceleration and speed?

    hello purple, I use the R & D plate and i modify it with the skeggs in place. It handles and tracks very good. Plus the extra speed you get with the plate. If you have any questions you can reach me at 727-365-5132 thank you, Jim

    Phillip - its an 04 Model.
    Jim - When I get closer to my purchase I will give you a call. Is it true that you have to grind in order to fit your plate? If so is there any info/instructions on this?
