they don't need to be bled. first try using the reach adjuster on the lever itself. sometimes that will bring the lever out away from the bar so it will change the engagment point.
the slightly more difficult trick/fix is to take the front wheel out. squeeze the lever a couple of times to move the pistons in, and now try and put the wheel back in. the rotor should just barely fit with only 2 squeezes... you may have to spread the pads with a clean screwdriver/tire lever/cone wrench, but get them wide enough so that the rotor goes in. tighten the QR...and now try the brakes. they should now engage further away from the grip. you can experiment with this a few times to get it right. you are basically resetting the stops for the pistons. this is extremely common with avid brakes and it's an easy fix.
