Spark plug
Check and replacement
- Remove the spark plug when the engine
is cold. Replace the spark plug every 12,000 km. The
use of unsuitable ignition control units and spark plugs
other than those specified can seriously damage the
engine.
Recommended spark plug: CHAMPION RG 6 YC
NGK CR 7 EKB
- Put the vehicle on the central stand.
- Open the door on the left side of the vehicle by
levering in the recess in the lower part of the door after
removing the screw.
- Disconnect the spark plug HV cable cap.
- Unscrew the spark plug with the spanner provided.
- Check the spark plug to see if the insulator is cracked,
the electrodes are worn out or excessively sooty. Also
check the condition of the seal washer and measure
the spark gap with a suitable thickness gauge.
Spark gap: 0,7 - 0,8 mm
- If necessary adjust the spark gap by carefully bend-
ing the side electrode.
If the spark plug has any of the defects mentioned
above, replace it with a plug of the recommended
type.
- Insert the plug into the hole with the proper inclina-
tion, screw it in fully by hand and then tighten it with
the specially designed spanner.
Tightening torque: 10 N·m (1 Kg·m)
- Push the spark plug cap all the way down onto the
spark plug and then proceed to the reassembly.

Warning
Air filter
- Remove the left-hand lower side panel as described
in Chapter 8-Bodywork.
- Remove the cleaner cap after loosening the eight
fixing screws, including one screw of the knob type.
- Pull out the filter element.
- Replace the air filter with a new one.
Note
: Check and if necessary blow the air filter every
6,000 km. Direct the air jet from the inside to the outside
of the filter (i.e. in the opposite direction to the air flow
during normal engine operation).
- If the vehicle is mostly used on dusty
roads, the air filter needs to be cleaned and replaced at
shorter intervals than indicated in the Maintenance
Schedule.
- Do not run the engine if the air filter is not
in place as this would result in excessive wear of the
cylinder and piston as well as in damage to the throttle
body.
