Ducati HYPERMOTARD 939 Owner's Manual page 137

Adjuster (2), located on the lever, allows a maximum
adjustment (Q) of 11 mm, whereas the standard
adjustment (starting one) is of 5 mm. If working on
such adjuster proves insufficient, work on the
secondary adjuster (3).
Warning
In case of a slipping clutch due to clutch wear,
adjuster (2) on the lever must NEVER be loosened,
but screwed, as described above.
If the clutch is still slipping, go to a Dealer or a Ducati
authorised service centre.
