Checking The Engine Timing - Ducati SCRAMBLER 800 Workshop Manual

Checking the engine timing

Remove the spark plugs and install tool (A) no. 88765.1297 in the spark plug bore to determine the
piston TDC, fit gauges (B) no. 88765.1581 and the timing check tool with degree wheel (C) no.
88713.0123.
Set the opening valve clearance to zero when the camshafts are in rest position by fitting a feeler gauge, of
suitable thickness, between the opening rocker arm and the opening shim.
Check that in this condition the camshaft can rotate. If it moves stiffly, use a thinner feeler gauge.
In this condition, with the piston of the horizontal cylinder at TDC with the valves fully closed as confirmed
by the reading with gauge (A), set the gauges (B) to zero.
Tension the belts according to the value specified in paragraph
Turn the degree wheel (C) counter clockwise until the gauge dial (B), on the exhaust side, shows a lift of 1
mm.
Check that the value of the angular displacement read on the degree wheel (C) is the specified one.
Valve lift — valve clearance of 0 mm
