Cleaning and replacing the spark plugs
(fig. 189)
Spark plugs are essential to smooth engine running and
should be checked at regular intervals.
The condition of the spark plugs provides a good indication of
how well the engine is running.
Have the spark plugs inspected or replaced at a Ducati Dealer
or Authorised Service Centre; they will check the colour of
the ceramic insulator of the central electrode (1): an even
brown colour is a sign that the engine is in good running
order.
Note
Inspect the centre electrode for wear and check spark
plug gap, which should be:
0.8÷0.1 mm.
Important
A gap outside the specified limits will adversely affect
engine performance and may lead to difficult starting or
erratic idling.
0,8 ÷ 0,1 mm
