Just purchased a used (2250 miles) 14 WG and I'm replacing various bits from the orig owner. Joker machine air cleaner w/ the 4" K&N filter. Not sure what else it fits, but its pretty small so if the bolts line up, I dont think it will interfere with much else. There is a number on the back of the housing (090525-1) and another number on the back of the engraved front piece (090109-3D).
A few bugs, but no dents or scratches.

Doesnt include gasket as it was destroyed removing from bike.
