    Smile ski bogging down

    Hello everyone hope the weather is warming up and you are all getting a chance to go out.
    My question is i have just finnished installing the riva stage one kit on my 07 gpr, so i took the ski out yesterday in the ocean and i might be dreaming but i am sure it is bogging down as you take off from a complete stop i know it is a lot louder.
    Is there some other mods i can do to fix it or make it realy go

    Red and RPM seem ok but you might want to try bringing the yellow down a bit and green too and see if it takes the bogging away.

    What altitude are you located at?

    To help the holeshot you can try the jetworks mod.

    Bring down the yellow to around 6 and the green to about 3.
    Then go up on each one until you either start runing rich or you get the bog again.

    The heads will give you a really noticable gain because it will help you move that 14/20 out of the hole.

    And if your going to go that deep into the motor (reeds) you should get the VF3's.

    The Jetworks Kit will keep that waterbox dry out of the hole and give you a smoother take off.

    With head, VF reeds, open airbox (no filter), bucket removed, opened air dams, keyway, D-plate, ect, I am at 3-3-1-7. When I tried the recommended settings I had a bog off idle, wet plugs, and excesive smoke at idle. Changed the settings and she was all better. It actually ran a little better with 2-2-1-7 but the engine sounded a little lean so I turned them to 3-3 for safety.
