Does your ktm contact/friend know how the professionals use the cover. Do the pros modify the stock filter, or is there some "works" filter made but only offered to the pros?

If you drill the hole put some grease on the spot where you drill.

Another option, being that the metal base of the paper filter is very thin. Perhaps you could "punch" out the hole from the interior side. Might take some Jerry rigging and making your own punch, say maybe a screwdriver with its end sharpened to a point.
