Check the engine coolant and inlet air temperature sensors as these are critical to proper air-fuel calculations. In fact check that the coolant system is working correctly (radiator level good, thermostat working, etc.)
This bike runs very clean emissions-wise so you should never really see any soot or smoke, especially if you do a lot of highway runs.
Those MPGs sound a bit low so it could be running rich, which would cause engine performance to decrease as it warms up. Could also need the CO adjustments checked. When was the last time you did a TB sync?
If your bike is stock I would not run premium fuel in it, you may be getting carbon buildup from the slow fuel burn and the 2005's lack of a fuel trim feature.
The dragging brakes check is also a great suggestion I have seen a few threads on here about sticky caliper pistons and if you ride in the rain and crud a lot, you most likely need to do some servicing.
