    Motorcycle carbs on watercraft?

    Hi. Im new at this forum, and this is my first post. I was wondering if anyone has mounted a motorcycle carb on his/her watercraft?
    I have a pair of Keihin FCR-39. My plan is to put them on my Polaris 700 with single carb. It works on a MX witch jups up and down all the time. Anyone have any experience?

    Carbs must be of a type that does not have fuel venting to interior of hull.

    Why change from the OEM carbs?

    They could work, however, the overflow could cause you to go BOOM

    I want to have better throttle respons and hopfulley more hp. Theese carbs comes from a 900cc motorcycle engine, and are a better carb then OEM. I allready have them, and was thinking of putting them on my Polaris. They are "flatslide" carbs. So you dont think they will work?

    Anything can be done and yes you can get them to work but itís a Big waste of time and money even if you have the carbs you will need MUCH more than just the carbs. As Crazy and K447 states Boom if itís not done right and after all that work there no Coast Guard Approved. Throttle response you say? Bump the compression 15-20 Psi put some Prok air cleaners and Tune the carbs right and prop the boat and you will get more out of it and be happier. Sell the Keihin FCR-39 and get ur money out of them.
