    Riva stage 1 help or advice

    Riva Yamaha GP1300R Free Flow Exhaust Kit

    I see that it is a blue hose and I think I have the Riva satage 1 but I can't see this in the engine bay. I'm wondering if I have the full stage 1 kit or just some of the pieces from the satge 1. It there any way to tell if I have the things below that I'm unsure about? Thanks


    I know it has
    EFI
    solas impeller
    87mm pump exit nozzle
    Grate
    trim tabs
    ride plate
    Sponsons


    I'm unsure if it has
    Flame arrestor
    D-Plate
    pump seal kit
    Free flow exhaust

    logotech where do you live?
    Freeflow exhaust is blue tube leading towards th back outlet of the ski.
    Pump plug kit is underneath the ski in the pump shoe
    Flame arrestor is in place of the airbox.

    I live in Cleveland Ohio I don't even know what a pump shoe is? I know what an air box is but I'm not sure what it looks like.

    I know I'm an idiot. But we have to start somewhere.

    Welcome to Greenhulk!

    If your ski is on the trailer and you crawl under it. You will see the intake grate and the metal piece that "shovels" water into the pump. That is your pump shoe. You can usually tell if it has been sealed if there is silicone in the seams around the pump shoe and hull and further in the pump tunnel where the shoe meets the pump tunnel. If nothing has been done you will see the pump shoe with no silicone and it comes right off when you remove the 4 bolts.

    As far as the free flow, you will need to remove the battery box and peak at the back of the hull. The free flow is a big blue tube. The stock sound suppression is black and fits back there like a puzzle.

    As far as your airbox, the best way to see it is if you remove your front bucket and look towards the motor. You will either see a metal filter in the lower left as you look in the front towards the motor or a black box the bends with a funky looking ball and another box that goes towards the center of the ski. The funky box is stock and the filter is aftermarket.
