    GP1300r Riva Stage I kit????

    I have a 2007 yamaha GP1300R with 20 hours on it. I've been looking at performance parts to begin a small winter project for next summer. I keep looking at the Riva stage I kit but i dont know its worth the money or if theres some better companies like R&D and Skat Trak for impellers. Its the first the time i'll be working on a waverunner so i don"t want to go to crazy with installing or rebuilding stuff for now.

    Start with

    Tunnel Reinforcement Kit
    Pump Plug Kit
    Intake Grate
    Ride Plate plenty to choose from.

    What type of riding and what do you want out of the ski.

    +1.... mike's list is the only place to start modding a gpr,forget you stage kits till you got above list underway,

    tunnel reinforcement will keep you from sinking one day
    intate grate.. stock will kill you soon
    ppk... good mod and cavitation is greatly reduced from this
    ride plate... as mike says have a good search on forum and pick one suited to you riding conditions

    I am really looking for good accelleration and i like riding canals so i'm also looking for a ride for turns but also for when we go out into the bay and ocean. A nice versatile set up.

    so you want the best of all worlds rolled into one

    have a read up and search on some of the old set ups posted about,

    most of all read up on mikes list and start there,there is no way i would ride with a stock grate let alone in tight turns at speed

    i just looked at the Riva pump seal kit, intake grate and ride plate. I like accleration and turns. It can get boring going straight all the time

    Agree with Paul get ridd of the that grate ASAP.

    Also i would go with a custom ride plate done by Jim or Carl over the RIVA plate.

    To make your choices simple if you ride allot in ocean and rough water the stock plate is hard to beat but not a speed gain.

    If you ride mostly carm water and some ocean riding then 110% custom plate

    Me i would go custom plate i have been able to fine 2 x sweet spots for general riding and speed runs and rough water or ocean riding.

    Use the search feature you will found tonnes off info.

    Let's not forget the jetworks mod for accel.
    and get rid of the plastic steering nozzle.

    To add:

    Trim tabs,sponsons,and the power filter are NOT needed in this Riva stage 1 kit and are a waste of money.

    Tell us what your expectations are for performance.
