Changed a leaking rear master cylinder on my K75 yesterday, and wanted to use my Tempo vacuum oil changer to bleed the line, but I had loaned it out.
Looking around the garage I found my two bottle rig for balancing throttle bodies. Connected the vacuum side of one of the bottles to the vacuum port on cylinder #2 and the other side to the ABS bleeder, fired up the engine and opened the bleeder. Took about a minute to bleed the line.
Sweet...
