PO had 155/55 combo in there and it was too rich. I was getting low 40s mpg if I was lucky. The air screw is about 1-1/2 turns out and it has very little affect on overall performance and MPGs.
I think the bike is still a bit rich on top as it runs a little better in the cool mornings than it does in the afternoons on warmer days. I gets a bit of a flat spot in the upper mid range as it comes off the needle. Pulls great off the bottom end in all conditions.
