You need to take your bike on a real ride. 100 miles + outside the city at 55mph+. You'll get GOOD mileage, but not 50+mpg. For your first trip, you should be able to get 100 miles per tank pretty easily. It will get you accustomed to flipping to reserve. It will also give you a broader scale of how far you can go once you flip to reserve.
It's also less-accurate to judge your average fuel consumption based on .943 and .920 gallons of gas at fill-up rather than 2.5013 and 2.4918 gallons. I'm not saying you've done this, but you if it doesn't match up to your 100 mile experience, don't be surprised.
