I switched to a UNI filter, pulled the snorkle, drilled two baffles out, and moved to 125 mains. It's a little bit louder than I had planned on, but it still gets drowned out whenever a Harley passes, and I rode 110 miles today on right around 2 gallons. Those are highway miles, not city miles, but so far so good ... that represents about a 20% increase over my highway MPG from two weeks back.
Thanks for the suggestions everyone.
