Well..... I don't know. I did the opposite. I changed to DOT 3 in both systems.

There is a lot less fluid in the clutch system so a flush should be easier. But again I would flush the system with a lot of fluid so as to get all the old fluid out. Since the clutch system is so small you could remove both the slave and master an clean by hand.

I do use hose shaped insulation on both the brakes and clutch line.
