my best results have been with compressed air also. Bleed the air out with a vac pump or by running a line from the bleed screw back to the M/C. and pump the pedal a few times. Put the cap back on the reservoir and blow about 10psi into it. Pedal should be tight at this point. Stop there! If you open the bleeder again you will lose pressure. I spent a day and a half trying to bleed my first one and it only took two minutes once a old timer showed me that trick.
