sounds like there is still air in the system. what i like to do is let the bike sit for a night with the handle bars turned full left so the master cylinder is at the highest spot.
then in the morning come out take off the resivore cap. and just giggle the break lever... dont push it in to far just giggle, i bet some air bubbles come out. Then blead the air out of the calipers as air has probably accumulated at the high point where the bleeder screws are.
Question are you using the standard, pull lever in untill resistance, open bleeder screw, close bleeder screw, let lever out method?
