i went ridin this weekend with my buddy who also has an '07 500 and he milked his oil by getting it too deep.... airbox was full of water. the guys we were riding with had polaris 700s and they helped us get his bike started up again. they were takin a look in the airbox and saw the crankcase vent is under the airfilter. its the little rectangle box with the piece of foam on top of it. they were telling me to prevent water from getting in there (if the airbox should ever fill up again) to put a hose in that crank case vent and run up a few inches higher... to the top of the airbox. has anyone done this?
