I, and have read accounts from others, have experienced front brake sponginess following flushing that has eventually gone away. Some have claimed that "microbubbles" need to work their way to the master cylinder. I don't know about that but I do know that the condition dissapears in a matter of hours.... overnight for sure.
I also have found it necessary on some bikes with clip ons to lean the bike hard to the left to let air escape the banjo fitting on the brake master cylinder (lean to the right for the clutch). Don't recall if it was ever necessary on the S but definately was on my Ducatis. Loosening the banjo while appling the brake will achieve the same thing. Just tighten it before releasing the handle.
