I've got dry filters on both of mt B's. They are available for 1-bbl carbs but they're tiny, so I made an adapter to be able to use a 4-bbl air cleaner.
Mr. Gasket offers a plastic adapter, but it's very flimsy, and crushes when the top wingnut is tightened. I got rough dimensions from it and made a 2-piece adapter from aluminum. Works good.

If you can't fix it with a hammer and screwdriver, you need a bigger hammer.
