I had to push nearly two quarts through my system before I got all the air out. It is an M110/R107, but same basic system. After two less-thorough bleeding attempts, it was still behaving as you describe.

It sounds like you still have some air in the clutch system. Try putting a power bleeder on the resevoir, and have someone pump the pedal while you watch from below. Use clear tubing and watch closely for really tiny bubbles.
