There I was enjoying a nice ride on my RT when I noticed what a wonderful color of amber my brake fluid made in the resiviour. Then I looked over at my clutch res and it looked black. Momentary panic as usually black brake fluid is bad news, but then I recalled that the clutch uses mineral oil and perhaps has a darker tinted resiviour. But dang me I cannot remember. Find it hard to believe a master going South at almost 4000 miles so I am hoping someone out there with an RT can go look at their's and get back to me.
