Whats the make/part number for the OEM filter?
I can find a bikemaster filter around here that says itll fit the bike, those any good?
EDIT: btw i dont live in a very dusty area, BUT the parking lot at my work is all dirt with 18 wheelers driving through it all the time. My car is covered in a layer of dust everyday. And i do ride my bike to work. I cover it so it doesnt get all dusty but riding in and out of the lot itll suck up a good amount of dust on a dry day
