For it's first 10,000 miles or so; my Spyder averaged 39.3 mpg.
After the trip to Missouri at the end of April, I noticed that it was getting noticeably better fuel mileage.
Since I hit 13,000 miles: it's been averaging 41.6 mpg.
When did you guys notice that things had loosened-up, and your bike was ready to start running the way that you knew it could?
