Cleaning And Replacing The Spark Plugs - Ducati 2006 SUPERBIKE serie Anleitung- Und Instandhaltungsheft

Cleaning and replacing the spark plugs (fig. 80.1 -
fig. 80.2)
Spark plugs are essential to smooth engine running and
should be checked at regular intervals.
Spark plugs condition provides a good measure of engine
condition.
Have the spark plugs inspected or replaced at a Ducati
Dealer or Authorized Workshop. Firstly, they will check the
colour of the ceramic insulator of the central electrode: a
light brown, even colour is a sign of good engine condition.
Notes
The motorcycle can either be fitted with spark plugs
with ground electrode (1, fig. 80.1) or with spark plugs
without ground electrode (2, fig. 80.2).
If it is fitted with spark plugs with ground electrode, the
wear of the central electrode and the electrode gap will
also be checked. The latter must be:
0.6-0.7 mm.
Important
An electrode gap outside the specified limit will
adversely affect engine performance and may lead to
difficult starting or erratic idling.
0,6÷0,7 mm
