Is the master cylinder the highest component in the system? Do all the lines have a downwards slant away from the master cylinder (no loops)? If gravity bleeding doesn't help then I would be suspicious of the master cylinder. It wouldn't be the first brand new master cylinder I have seen not work properly. (It took three on my Javelin to get a good one) I am assuming you have checked every tubing connection for leaks. Use a dry paper towel to check for leaks as a small leak will be very evident on a clean dry paper towel.
