Cleaning And Replacing The Spark Plugs - Ducati Superbike 848evo Corse Owner's Manual

Cleaning and replacing the spark plugs

(fig. 96)
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 Authorized Service Center; they will
check the color of the ceramic insulator of the central
electrode: an even brown color is a sign that the
engine is in good running order.
Note
Inspect the center electrode for wear and check
spark plug gap, which should be:
0.03-0.004 in (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 (0.03 ÷ 0.004 in)
