If a clutch lever goes "all the way back" with no play at all, it's not adjusted properly.
There should be 10-20mm if play in the lever.
If there is no play, the cable is too tight, and can cause clutch to slip. (Unless there is a spring or something in the clutch lever that takes up the lever slack, but I know the stocker doesn't have such a thing.)
I have the freeplay. But, after I apply the clutch, the lever stops at the end of the freeplay ( from where you have to actually apply pressure to clutch lever) and doesn't return back all the way back.
