Hello, Few days ago made a post about same thing but was in a major hurry hehe.
Ok first off have a 02 650 prarie. Started scouting few days ago after not riding it for
like 2 months been started a few times about it, Anyhow after a hour or so of riding
my bike started cutting out like it had bad gas or somehing when just setting still it idles fine just when u give it gas it trys to cut out.
I took seat off and air filter out Seems there what looks like misty water, oil or some sort blowing out of what i think is the drain hole for the air box i tryed to follow the hose but it dissapears behind the motor and not had time to see where it goes anyone have any ideal what this hose connects to, and why it would be blowing mist or something in my air filter? Any help of where this tube goes would be a start Thanks.

In the Air box theres only the intake for the air box, 2 carbs and bottom right of the air box is a drain about the size of a quarter and that is what the water like misty im seeing.

That hole is the crankcase vent. It goes directly to the engine. If it's blowing out water, it's because there is water in the oil.

 

Hey again! If the hole in the air box is the crankcase vent, And the water misting out of that vent is from the crankcase would it cause it to cut out like it has bad gas or something? It runs fine sometimes but sometimes cuts out bad to not sure if water in the oil would cause it to do that? I checked the oil just the dipstick Only and the oil don't look milky so not sure what else it could be? Any info would be great gonna change the oil in a few days when i get time just been abit short on that this past few months hehe.
