•
Rotate the crankshaft until the left cylinder piston is actually at the top dead centre (with
valves closed).
•
Reset the dial gauge and make sure the references (on the timing system gears and the
engine pinion) are perfectly aligned, so that looking through the checking hole on the gear-
box, the reference line marked 'S' is perfectly aligned with the reference marked at the centre
of the hole.
•
Align the arrow point with the TDC zero on the graduated dial.
•
Observing the timing system diagram,
check timing considering that:
A - intake start opens 20° before TDC
B - exhaust end closes 10° after TDC
C - exhaust start opens 44° before BDC
D - intake end closes 50° after BDC
•
Screw the dial gauge support and then the gauge itself on the right cylinder outer spark plug
hole.
•
With a screw, fix the arrow to the threaded hole to the right of the crankcase.
•
Turn the disc clockwise until the reference marked with letter 'D' is aligned with the reference
at the centre of the checking hole on the gearbox (valves closed).
•
Repeat the operations described above for the left cylinder.
•
After the check and if everything is correct, operate as follows to restore the operation clear-
ance between rockers and valves (intake 0.10 mm (0.0039 in), exhaust 0.15 mm (0.0059
in).
•
Remove the graduated dial hub, the graduated dial, the arrow, the dial gauge support and
the gauge itself.
