- Otherwise, adjust the right headlight by the screw
shown in the figure, which can be accessed by re-
moving the front shield connecting member.
N.B.
THE ABOVE PROCEDURE COMPLIES WITH THE EURO-
PEAN STANDARDS REGARDING MAXIMUM AND MINI-
MUM HEIGHT OF LIGHT BEAMS. REFER TO THE STATU-
TORY REGULATIONS IN FORCE IN EVERY COUNTRY
WHERE THE vehicle IS USED.
Checking the end compression pressure
- With the engine cold remove the sparkplug cap.
- Remove the sparkplug.
- Fit a compression testing pressure gauge in the sparkplug seat with a 10 mm sparkplug fitting tightened
to the correct torque.
- With the switch on "ON" wait a few seconds and then disconnect the rpm-timing sensor to disable
operation of the injector and sparkplug.
- Run the engine using the starter motor and with the throttle body fully open, until the reading on the
pressure gauge is stable.
- If the pressure is greater than XX - XX, remove the device and reassemble the vehicle.
- If pressure values lower than those indicated are measured, check the engine rpm used for the test;
if under 450 rpm, check the starter system.
When the compression end pressure is under the norm, remove the fitting from the pressure gauge and
pour a few cc of oil in the combustion chamber, rotate the engine (preferably by hand) to lubricate the
cylinder.
Repeat the pressure test:
if the new values are still low check the valve seals.
Higher pressure values of a new engine indicate poor sealing of the parts.
