are you 'bench bleeding' the master cylinder right in place ?
you know ..
the 'open line nut, push pedal about half way down' close nut, release
pedal, pause, repeat'  -
that method on each line a few time ..........??

important not to stroke on old Master cylinder all the way to the floor -
damages the seals in the mc.

Well... I can pump and pump and pump and the level doesn't go down at all
in the container on the top.

I will crack open each
junction on the master cylinder and see what happens. Then I guess
if that works, go to each corner and inspect... sigh... I wanna get
my motorcycle out of the shop!!!!
