Checking The Idle Speed - Ducati Diavel Workshop Manual

Diagnostic instruments
Flick the belt lightly with your finger and read the frequency value (Hz) on the DDS diagnosis instrument.
Note
Do not stress the belt several times repeatedly, since the necessary minimum time for the DDS diagnosis instrument to
take a reading is 1 second.
The tension values are those detailed in Sect. 3 - 1.1,
cold: assembly values must be applied with when installing a new belt, while service values must be applied when belt
tension reaches 70 Hz.
Warning
The timing belts can become slack during normal operation. When checking belt tension, if the reading is less than 70
Hz, retension the belt to restore the specified nominal values (Sect. 3 - 1.1,
If the tension value is incorrect, increase or reduce belt tension, moving the adjustable tensioner pulley (23), loosening
the nut (24): to tension the belt use the tool with part no. 88713.3497.
Tighten the nut (24) securing the tensioner pulley.
Recheck the timing belt tension.
Repeat the above procedure until the correct belt tension is obtained.
Once the belts are correctly tensioned, ensure that the fixing nut (24) of the tensioner pulley (23) is tightened to a torque
of 25 Nm (Min. 22 Nm - Max. 28 Nm) (Sect. 3 - 3,

Checking the idle speed

Check that the bike is provided with electronic control unit, OEM intake and exhaust systems, otherwise fit original
