-- while it sucks, i guess i have "written it off" as part and parcel for the brand - there have been all kinds of attempts at a fix for it:
-replace slave (sc)
-replace master
-wrap the clutch line
-pin hole in rubber boot on lever at mc to stop supposed air being pushed or sucked into system
-different fluids
-stop the spinning rod in sc to prevent fluid boil
-spacer plate for sc to allow more air to cool things off (prevent fluid boil)
-new o-ring on sc to stop its deterioration there-by contaminating fluid (it was thought by someone that the blackness was the breakdown of the o-ring)
-- seriously, i have "heard it all".....i hoped all along there would be a simple solution, or Ducati would have done something......evidently not - hopefully something will eventually come of it, but in the mean time an 11mm seems to answer it
-- until something truly definitive comes along, the new mini bleeder from motion-pro is something to have fun with, so.....i've given up
