Cleaning and replacing the spark plugs (fig. 73)
Spark plugs are essential to smooth engine running and
should be checked at regular intervals. This provides a
good measure of engine condition.
Contact an Ducati Dealer or Authorised Workshop to have
the spark plug checked and changed, if needed. Their staff
shall check the color of the ceramic insulator on the central
electrode: a light brown, even colour is a sign of good
engine condition.
Check wear on the central electrode and the gap: it should
be 0.6-0.7 mm.
Important
If gap is too wide or too close, engine performance
will be affected. This could also cause misfiring or irregular
idling.
