im sure the filter does, but not sure. all i know is when i take it off there is some oil on thr inside but not like my old low profile filter i ran on the stock ht, that thing woukd soak in oil and id have to wash it once a week or twice
The tank has to vent for everything to work right, below is a link to what I would use.

The way I would do this is I would order the vent tube assembly, and when I got it I would find me a piece of small steel or brass tubing that the clear vent tube will fit snugly over, I would drill the hole in the gas cap so that the steel or brass tubing will just fit through the hole, I would braze the tubing into the gas cap myself but if you dont have access to a torch and the know how to braze I would simple go buy some JB Weld, clean all the parts very good with carb cleaner to remove any oil and then I would JB Weld the metal tube into the gas cap, let it cure over night slide the vent tube on the metal tube and walah.... you are venting that tank now.

You can also just put the metal tube into the gas cap like I described and then just run a 2 or 3inch piece of fuel tubing straight up off of it and vent it that way without buying the "fancy" little tank vent, my old dirt bikes vented with just a tube run up off the fuel cap, they didn't have anything on the end of them, so that will work just fine also.

I'd vent the gas cap before I went into the carb just to see if that will fix it, if not then I'd check the float level in the carb. no need to risk messing up a bowl gasket if you dont have to....

I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
