    Bypass Valve Question (250x)

    I just did the secondary waterbox delete (07' model) by trimming the factory exhaust pipe allowing me to eliminate all the additional tubing so it runs straight from the primary waterbox into a "U" shaped stainless 2 1/4" pipe and then straight out the back of the ski, the dual bottom feed intercooler mod, the crank case vent mod, and and removed the tube from the bypass valve that goes back to the airbox (intake). I was going to install a filter directly on the valve, but I can't find a filter locally and want to run the ski tomorrow. Has anybody just vented the bypass (relief) valve to a heater hose into a secluded place in the hull, or just let it vent into the hull with no additional hose? Or do you think a filter is necessary as a result of the oil that may possibly get into the intake system? Thanks in advance for any help. Keith

    sounds like you have been busy, you could just vent it temporary without a filter as it only blows air out but it could get a bit messy best try and get a filter imo

    why didn't i think of that i must have still been on a high after todays 140km ride around one of our bays on water that was like glass.

    another thought you could vent it outside the hull where others have done.
