Tex, If I remember, the book procedure involved washing them in gasoline and allowing them to dry. Not the safest thing in the world to do. I don't have a Bugeye book handy to verify that.
Vicky Brit sells foam pancake filters for the H1 carbs, but I dont know how efficient they are. I dont think K&N has them for the H1's, but, you can get K&N filter assemblies with uncut base plates so you can adapt them to fit anything.
I'm assuming you still have the H1 carbs on it? If you have switched to HS2's, you have all kinds of options.
