Ignition system
The engine is equipped with an electronic
ignition system. Only the spark plug requires
maintenance.
For recommended spark plug, see “Technical
data”.
1.
Remove the ignition cable boot and clean
around the spark plug.
2.
Remove the spark plug with a 13/16î (21
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 0.7-0.8
mm/0.028-0.031î. 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
using a spark plug wrench so that the
washer is compressed. A used spark
plug should be turned 1/8-1/4 of a turn
from the seated position. A new spark
plug should be turned 1/2 a turn from the
seated position.
7.
Replace the ignition cable boot.
IMPORTANT INFORMATION
Fitting the wrong spark plug type can
damage the engine.
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.
