I have Galfers on my GSXR front and rear...I LOVE them, and swear by them! (SS lines vs. OEM rubber) I installed them myself, and a couple things i can offer are...
1) Be patient when bleeding the lines. Mine took a little while before the fluid started moving after it was completely drained.
2) Once the fluid is pretty much replaced, I jiggle the lines when I bleed them to shake loose tiny air bubbles trapped inside the lines. Once I get no more bubbles, I build up the pressure, and purge the system at the banjo bolt up by the master cylinder. Of course, I put a rag underneath so I dont get fluid all over the shiny parts. But I purge it once or twice up there, just to make sure all the air is released that may have been trapped up in the upper crevices...
Hope this helps you...Let us know how it turns out!
