I bought an 85 with a 305 and when I pulled the breather assembly the air filter was some type of small, metal mesh filter (no paper at all) and it is GLUED to the bottom of the breather. It looks like they used liquid nails. I've seen K&N's and other fancy filters, but this is something completely different. Does anybody have a clue as to what type of filter this is, and moreover, why it's so fantastic that you permanantly adhere it?! "who dares wins"
