Cut the 2x4 so it will jam between the seat and the brake pedal. Pump the pedal a bunch of times, and hold the pedal down with the 2,4 jammed against the seat. Get out and get under, let the air out of the r/r cylinder. You will get quite a bit, because all that pumping compressed the air in the other cyls. Check m/c fluid, do it again. 2-3 times per cyl, working closer to the master. Finally, the left front is different, because by then you lack the capacity of the other three cyls. So now, get under the l/f fender, pull the brake pedal down by hand, pump it up, let the air/fluid out at the bleeder. Works for me.
Two man works well,"Pump it UP" "Down" "Up" "pump it up" Down""fill it up""Pump it UP" "Down" "Up" "pump it up" Down""fill it up""Pump it UP" "Down" "Up" "pump it up" Down""fill it up" But there are fewer trips up and down than with my one man system. Helps if you #2 man has good hearing...
I've never managed to catch the old fluid by using a hose and bottle, I just let it squirt into a rag, listening and looking for bubbles. Problem with the check-valve type gizmos is that bleed screws let air get sucked in up the threads. Pressure bleeding works well, only if the screw on top of the m/c doesn't leak.
