into the vicinity of the battery.
Check the level of the battery acid
Check that the level of the battery acid lies between
the markings. Top up the cells with only distilled
water.
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”.
IMPORTANT INFORMATION
Fitting the wrong spark plug type can damage
the engine.
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 0.75 mm (0.030"). Adjust as
necessary by bending the side electrode.
5. 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.
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 of a turn from the seated position. A
new spark plug should be turned
1/4 a turn from the seated position.
7. Replace the ignition cable shoe.
