Ignition System

The engine is equipped with an electronic ignition

system. Only the spark plug requires maintenance.
For recommended spark plug, see “Technical data”.

Remove the ignition cable shoe and clean around

the spark plug.
Remove the spark plug with a

" (21 mm) spark

plug socket wrench.
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.
Measure the electrode gap with a gapping tool.

The gap should be 0.7-0.8 mm/0.028-0.031".

Adjust as necessary by bending the side electrode.
Reinsert the spark plug, turning by hand to avoid

damaging the threads.

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.

After the spark plug is seated, tighten it using

a spark plug wrench so that the washer is

compressed. A used spark plug should be turned

1/8-¼ of a turn from the seated position. A new

spark plug should be turned ½ a turn from the

seated position.
Replace the ignition cable shoe.
