1- You can't get accurate mpg estimates by eye-balling fillups. You need to use a commercial program that tracks exact fills and it takes a minimum of three fills to do that. Try Fuelly.com online, or if you have an Android phone, you can use an app called Fuel Log. If you have an iPhone, get rid of it, and buy an Android.
2- I wouldn't even begin sweating mpg at all until you're done with break in + 500 miles. Your engine will behave differently in a number of respects after 1000 -1500 miles, and an oil change *or two*. I didn't notice an improvement in mpg on my CAR until > 5000 miles, and on my 6R until > 1500 miles. You're also getting used to the feel of the bike in this window, if only sub-consciously, and will become more consistent with shifts, acceleration, and other aspects that can affect mpg after a thou miles or so (even if you think you are now).
So, give it some time, get a decent fill up tracker, and don't worry about mpg right now. Unless you're experiencing another overt issue with the bike, the mileage will improve on its own.
Ride safe, and enjoy your new Christmas present... it's a fabulous bike.
