The adjusting screw can be used for individual adjustment of the original
position of the clutch lever, thus allowing adjustment to an optimal position
for every hand size.
Turning the adjusting screw clockwise reduces the distance between the
clutch lever and the handlebar. Turning the adjusting screw counterclock-
wise increases the distance between the clutch lever and the handlebar.
