Ensure the reference mark on the camshaft control ring is
aligned with that machined on the head, as shown in the
second figure.
If the marking is on the side opposite to the reference on the
head, perform a complete revolution of the crankshaft, since
the piston must be at the TDC of the ignition phase.

HECKING
THE
VALVE
CLEARANCE
In order to carry out the inspection of the valve clearances,
align the reference marks as for the valve timing point,
described earlier.
Using a thickness gauge, ensure the clearance between the
valve and the valve adjuster is within the indicated values.
If the valve clearance values differ from those shown below
(for intake and exhaust respectively), proceed with the
adjustment, by loosening the counter nut and then, with the
aid of a screwdriver, loosening or tightening the adjusting
screw as shown in the figure.
