I haven't bled the ABS. I took the cover off and only found fuses and wires to the system. I don't have a CD. I had cracked the line after the ABS once and fluid came out. I figured that was good. I will look again for some type of bleeder screw.

A friend suggested that I try to isolate the problem by making some sort of plug with some new brake line. First at the M/C, then after the ABS etc. Maybe narrow it down to the front or back or a caliper. Sounds like its worth a try.
I'll let you know....
