Brad, you're right. Although the PS rear is geographically further, line distance wise, the DS rear is further. The line goes down from the m/c, across the cross member, along the PS frame rail, to the PS side of the rear end housing. The line from that junction is longer to the DS rear wheel cyl than it is to the PS, so yes: the DS rear is technically a longer brake-line distance from the M/C.

Bleed them like this: DS rear, PS rear, PS front, DS front. It is possible that since you're doing the PS first, you're getting air stuck in the lines on or near the rear end housing.
