Clutch system
If the control lever has too much play and the
transmission snatches or jams as you try to engage a
gear, it means that there might be air in the circuit.
Contact your Ducati Dealer or authorized Service
Center to have the system inspected and air bled out.
Warning
Clutch fluid level will increase as clutch plate
friction material wears down. Do not exceed the
specified level (3 mm above the minimum level).
