plug gap should be measured with a
wire 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.
NOTE:

If a torque wrench is not available when
installing a spark plug, a good estimateof the correct torque is 1/4–1/2 turn
past finger tight. However, the spark
plug should be tightened to the speci-
fied torque as soon as possible.
EAU45140
Engine oil and oil filter
element
The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter ele-
ment replaced at the intervals specified
in the periodic maintenance and lubri-
cation chart.
To check the engine oil level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
NOTE:

Make sure that the vehicle is positioned
straight up when checking the oil level.
A slight tilt to the side can result in a
false reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Wait a few minutes until the oil set-
tles, and then check the oil level
through the check window located
at the bottom-right side of the
crankcase.

Spark plug gap:
0.6–0.7 mm (0.024–0.028 in)

NOTE:

The engine oil should be between the
minimum and maximum level marks.
4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
To change the engine oil (with or
without oil filter element replace-
ment)
1. Place the vehicle on a level sur-
face.2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Place an oil pan under the engine
to collect the used oil.
4. Remove the engine oil filler cap
and drain bolt to drain the oil from
the crankcase.
NOTE:

Check the washer for damage and re-
place it if necessary.
NOTE:

Skip steps 5–7 if the oil filter element is
not being replaced.
5. Remove the oil filter element cover
by removing the bolts.

6. Remove and replace the oil filter
element and O-rings.
NOTE:

Make sure that the O-rings are properly
seated.7. Install the oil filter element cover by
installing the bolts, then tightening
them to the specified torque.
8. Install the engine oil drain bolt, and
then tighten it to the specified
torque.
9. Add the specified amount of the
recommended engine oil, and theninstall and tighten the oil filler cap.
NOTE:

Be sure to wipe off spilled oil on any
parts after the engine and exhaust sys-
tem have cooled down.
CAUTION:

ECA11620

In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.

Make sure that no foreign mate-
rial enters the crankcase.
