Checking Valve Lift - Ducati SCRAMBLER 800 Workshop Manual

Checking valve lift

Fit gauge (A) part no. 88765.1581 in the hole of the removed head cover as shown in the figure.
Set the opening valve clearance to zero when the camshafts are in rest position by fitting a feeler gauge, of
suitable thickness, between the upper rocker arm and the opening shim.
Check that the feeler gauge fork probe is centred on the valve axis and against the closing shim collar.
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.
Perform the same operation for the exhaust valve, by fixing the support on the cylinder head opposite side.
Refit the components by carrying out the same operations indicated in paragraph
valves" described above.
