    General speed question for Kaw 250x

    Does anyone know if they make a Speed Control Override Module for this model? I know they made it for the 300 and 310.... Through Riva Racing products

    I don't have 12 grand two drop so I race what I have and contunie to stay happy. I just wondered if they had that mod upgrade for my ski or not. I see Riva has it for the 300 and 310 only. But thought another company might have it. Yes my ski is vintage to a lot of you but its better then nothing and sure is good looking.

    Well I hope he chimes in. 70mph for my vintage ski would be very satisfying to me. I would like to know what his build was to get the ultra 250x at 70mph on a regular basis.

    The fastest I had my 250x was 71.9. It takes a few mods to get it there tho
    But a 2* wedge and a machined riva plate with a new Solas impeller made the biggest difference for me

    4-6 degree timing wheel modification(93 req), more air to engine bay(washers between hull and rear seat platform, bov hose delete, glovebox air filter), 2 degree wedge w/ riva plate, BOV blockoff, ride plate to hull trueing.

    a solid 74 is easy enough to do , but it will come at a cost...........not alot of money at first , but knowledge on the how to is not cheap.

    my best out of my 250 2007 was 75.6mph,

    That number would have been reached on an extremely flat body of water, on a cool temp day.
    Not possible with chop.
    And the hook up would have sucked, so no good for CC racing.
