Cleaning And Renewing The Spark Plugs - Ducati SuperBike 1098S Use And Maintenance Manual

Cleaning and renewing the spark plugs

(fig. 81)
Spark plugs are an important part of the engine and should
be checked at regular intervals.
Spark plug 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
E
the ceramic insulator of the central electrode: an even brown
colour is a sign that the engine is in good running order.
Notes
Secondly, they will check the central electrode for
wear and measure electrode gap. Electrode gap should be:
0.6÷0.7 mm.
Important
A gap outside the specified limits will adversely affect
engine performance and may lead to difficult starting or
erratic idling.
