There is a Uni Pod filter attached to an aluminum sleeve which is attached
to a rubber connector that fit's over the 38mm Mikuni. Rear splash guard
must be removed to gain access to the filter. The two top screws are removed
and the entire airbox is slid out the back, while the filter remains attached.
It's the standard VG 250 airbox, but I did add some vents to let in more air.
