    bilge siphon tube and waterbox

    has anyone thought to use the bilge siphon tube to remove water from the waterbox while riding? Im thinking about trying it. welding a bung to the bottom of the waterbox and screwing in a fitting with a hose connected to the bilge siphon tube hose on the transom plate. hopefully while riding will remove some of the water that builds up in the waterbox. trying to run as dry as a waterbox as possible. the tube would have a loop in it above the waterline to keep water from coming in while sitting.

    What is the point of doing this? If you blow out your waterbox after riding than you don't have anythign to worry about with the water in there. IMO sounds like a lot of work and a lot of things to go wrong.

    You have to have some water going through the water box and exhaust or you will melt the connectors......nothing really to be gained by doing it....but hey have at it and let us know..................

    island racing has a sweet kit for the GPR that gives you a dry watebox at low rpms and allows for waterflow at high rpms so it does not overheat the connectors.

    It's been done but results were never posted. My guess is it won't make a difference. If you've ever had the exhaust apart you'll see there is a restrictor plate in it to limit how much water goes to the water box...it's got a pretty small hole in it. I removed my R&D cooling kit, but I still have the included exhaust plate installed which has an even smaller hole than stock. I never noticed any improvement in holeshot with the R&D part.
