Ducati Diavel Service Manual: Checking valve lift

Set the engine to the configuration described for the "checking and adjusting the valve clearances", previously indicated.

Seat the plate (a) and tighten the screws (b).

Checking valve lift


Checking valve lift


Set the opening valve clearance to zero when the camshaft is in its rest position by fitting a feeler gauge between the upper rocker arm and the opening shim.

Lock the dial gauge into the seat of the stand marked "a" and position the fork probe against the face of the closing shim.

Set the dial gauge to zero when the valve is fully closed.

Rotate the intake camshaft so as to allow the intake valves to lift fully.

Check on the dial gauge that the measured value corresponds to the prescribed one (sect. 3 -1.1, Timing system/valves).

Repeat the same operation for the exhaust valves, using the dial gauge in the support seat 88765.1518 With the marking "s".

Refit the components by carrying out the same operations indicated in chapter "checking and adjusting the valve clearances", previously described.

Refit the components removed in the procedure.

Specific operating strategies
Idle speed No electric motor is used for idle speed regulation (bypass is modulated instead with the throttle valve), as idle speed control is effected by the ride-by-wire system. Idle speed is maintained by the control unit when the speed drops below a specific threshold and when the clutch ...
