a mask that you use for when your sanding timber or spray painting , you know the little paper type with the elastic to hold it on ya head and guess what they are waterproof and let heaps of air through. Just cut it to shape and poke the dome part up into the air filter and the rest between the filter and bottom of the airbox, and "presto" a waterproof prefilter. Oh and cheap too

I checked out a few of these masks today (Walmart), and they seem to be just paper - certainly not anything I would consider waterproof. Could you be more specific? Any one else have any idea?

I do want to "screen" that lower opening (maybe the top too?), but I'm still searching for the right stuff to do it.

I don't mind riding in the wet stuff, and sure don't want to compromise the engine by sucking in any fine dust or grit, but am having second thoughts about this mod until I can "condomize it" in some way.
