Don't know if you felt the clutch pedal change a little in feel as well...? but the clutch fluid and brake fluid are ran off the same reservoir....so if you have OEM fluid in the clutch line, it will boil before the uprated brake fluid will...and the clutch basically becomes fully depressed and doesn't release, 10 mins of cooling and it will return to normal, but just a heads up if it happens, its nothing too much to worry about...I have RBF600 in the clutch line and its never been an issue
