I swear I posted this earlier, but now the post is gone so I don't know. But has anyone heard of something called a Barrel Style Filter? Omar from http://www.omarsdtr.com/ suggested I use them on my XS instead of pod filters to increase the "tune-ability" of my carbs. He said I could get my local K&N dealer to order me some. Does anyone have a picture of this type filter by any chance?
