Just found this thread and figured I'd bump it up. I used to have a very short commute (7mi each way) and I got a consistent 28mpg. Now, my commute is up to 44mi one way and 37mi back. Over the past 10 tanks I've gotten 36mpg every time. Just this weekend, I took a 135mi straight highway trip. When I got home I still had 2 bars left on the gauge, filled up and got 44.88mpg! This is on my 03 with ZX10 TB's and pods, light flywheel, ZX9 header/muzzy slip on, PC3, timing advanced 4 degrees and always run 93 octane. Bike has ~22k on it.
