The engine oil should be between the minimum
and maximum level marks.
NOTICE
19 - 20
The spark plug is an important engine component,
which should be checked periodically, preferably by
a dealer. Since heat and deposits will cause any
spark plug to slowly erode, it should be removed and
checked in accordance with the periodic mainte-
nance. In addition, the condition of the spark plug
can reveal the condition of the engine.
The porcelain insulator around the center electrode
of the spark plug should be a medium-to-light tan
(the ideal color when the vehicle is ridden normally).
If the spark plug shows a distinctly different color, the
engine could be operating improperly. Do not attempt
to diagnose such problems yourself. Instead, have a
dealer check the vehicle.
If the spark plug shows signs of electrode erosion
and excessive carbon or other deposits, it should be
replaced.
Before installing a spark plug, the spark plug gap
should be measured with thickness gauge and, if
necessary, adjusted to specification.
Clean the surface of the spark plug gasket and its
mating surface, and then wipe off any grime from
the spark plug threads.
CHECKING THE SPARK PLUG
The engine oil level should be checked before each
ride. In addition, the oil must be changed at the inter-
vals specified in the periodic maintenance and lubri-
cation chart.
ENGINE OIL
1. Place the vehicle on the main stand. A slight tilt to
the side can result in a false reading.
TO CHECK THE ENGINE OIL LEVEL
1. Start the engine, warm it up for several minutes,
and then turn it off.
2. Place an oil pan under the engine to collect the
used oil.
3. Remove the engine oil filler cap and the engine
oil drain bolt to drain the oil from the crankcase.
4. Install the washer and the engine oil drain bolt,
and then tighten the drain bolt to the specified
torque.
5. Refill with the specified amount of the recom
-
mended engine oil, and then install and tighten the
oil filler cap.

2. Start the engine, warm it up for several minutes,
and then turn it off.
3. Wait a few minutes until the oil settles, remove
the oil filler cap,wipe the dipstick clean, insert it back
into the oil filler hole (without screwing it in), and
then remove it again to check the oil level.
4. If the engine oil is below the minimum level mark,
add sufficient oil of the recommended type to refill it
to the correct level.
5. Insert the dipstick into the oil filler hole, and then
tighten the oil filler cap.
