Cleaning and replacing the spark plugs (fig. 94) 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) 0,8 ÷ 0,1 mm (0.03 ÷ 0.004 in) 1 fig. 94 Important A gap outside the specified limits will adversely affect engine performance and may lead to difficult starting or erratic idling. 128
