Hey! You want a couple mm of slack in your clutch cable! You will burn up your clutch otherwise!!!!!!!It does move up and down loosely. No slack in the cable though. I have taken it apart to see if I could tighten it and the bracket itself is threaded and the boot the clutch lever pivots on is smooth and designed in such a way that the bracket cannot be overtightened. The lock nut you can see on the bottom of the bracket is just a redundancy.
