PERIODIC MAINTENANCE AND ADJUSTMENT
7-7
7To install the spark plug
1. Clean the surface of the spark plug gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
2. Install the spark plug with the spark plug wrench, and then tight-
en it to the specified torque.
TIPIf a torque wrench is not available when
installing a spark plug, a good estimate
of 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.3. Install the spark plug cap.
EAU49932
Engine oil The engine oil level should be checked
before each ride. In addition, the oil
must be changed at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
To check the engine oil level1. Place the motorcycle on a level surface and hold it in an upright po-
sition. A slight tilt to the side can re-
sult 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, remove the engine oil filler
cap, wipe the engine oil dipstick
clean, insert it back into the oil filler
hole (without screwing it in), and
then remove it again to check the
oil level.TIPThe engine oil should be between the
minimum and maximum level marks.
4. If the engine oil is at or below theminimum level mark, add sufficient
oil of the recommended type to
raise it to the correct level.
5. Insert the dipstick into the oil filler hole, and then tighten the oil filler
cap.
To change the engine oil 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,
the engine oil drain bolt and its
gasket to drain the oil from the
crankcase.
4. Install a new gasket and the drain bolt, and then tighten the drain bolt
to the specified torque.
5. Refill with the specified amount of the recommended engine oil, and
then install and tighten the oil filler
cap.
NOTICE
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.
6. Start the engine, and then let it idlefor several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
7. Turn the engine off, and then check the oil level and correct it if
necessary.
EAU39834
Cleaning the air filter element The air filter element should be cleaned
as follows at the intervals specified in
