Ignition system

The engine is equipped with an electronic ignition system. Only the spark plug requires maintenance.

For recommended spark plug, see chapter “Technical data”.

1.Remove the ignition cable shoe and clean around the spark plug.

2.Remove the spark plug with a 5/8" (16 mm) spark plug socket wrench.

3.Check the spark plug. Replace the spark plug if the electrodes are burned or if the insulation is cracked or damaged. Clean the spark plug with a steel brush if it is to be reused.

4.Measure the electrode gap with a gapping tool. The gap should be 1.02 mm/0.040". Adjust as necessary by bending the side electrode.

5.Reinsert the spark plug, turning by hand to avoid damaging the threads.

6.After the spark plug is seated, tighten it with 38-43 Nm (28-32 lbft).

7.Replace the ignition cable shoe.

IMPORTANT INFORMATION

Inadequately tightened spark plugs can cause overheating and damage the engine. Tightening the spark plug too much can damage the threads in the cylinder head.
