Put the bike on the centerstand, and put something under the engine to raise the front wheel off the ground. Spin the wheel. If you feel anything but very light drag, something is wrong. Check it after riding a few miles. If the discs are hot, then the brakes are dragging. If so, you will need to do something about it. If it seems to be the calipers, then they need to be disassembled, thoroughly cleaned, and put back together with all new seals, then bled properly. If you find any corrosion on the pistons or in the bores, you can polish it out with fine sandpaper. If you know the calipers are good, then the problem has to be in the fluid return hole in the master cylinder. You may be able to unplug that without taking the master cylinder apart. It should be a small pinhole in the bottom of the reservoir.
