It may have overadjusted and be dragging, just slacken the adjuster off at the pedal and it will readjust.
To do this lift the clutch pedal, then with your thumb/finger on other hand push the quadrant at the top of the pedal forwards so it slackens the cable, let go pump a few times and it will readjust.
I've found with cossie clutches you can't do a lazy change and do need to use every last mm of pedal movement, found this out as my left leg is 1 1/2" shorter than my right and I need a block on there like on me pedals on first bike!!
