6Before installing a spark plug, the spark
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 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. @
ECA00021
CAUTION:@ Do not use any tools to remove or
install the spark plug cap, otherwise
the ignition coil coupler may get
damaged. The spark plug cap may
be difficult to remove because the
rubber seal on the end of the cap fits
tightly. To remove the spark plug
cap, simply twist it back and forth
while pulling it out; to install it, twist
it back and forth while pushing it in. @

Engine oil and oil filter
cartridge The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:_ Make sure that the motorcycle is posi-
tioned 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.
a. Spark plug gapSpark plug gap:
0.6–0.7 mm
Tightening torque:
Spark plug:
12.5 Nm (1.25 m·kgf)

and wipe it clean, insert it back into
the hole (without screwing it in),
and then remove it again to check
the oil level.
NOTE:_ The engine oil should be between the
minimum and maximum level marks. _
5. If the engine oil is at or below the
minimum level mark, remove the
oil filler cap, and then add suffi-
cient oil of the recommended type
to raise it to the correct level.
6. Insert and tighten the engine oil
dipstick, and then install and tight-
en the oil filler cap.To change the engine oil (with or
without oil filter cartridge replace-
ment)
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.

CAUTION:_
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
higher 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.
_13. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.NOTE:_ After the engine is started, the engine
oil level warning light should go off if the
oil level is sufficient. _
EC000067
CAUTION:_ If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha deal-
er check the vehicle. _14. Turn the engine off, and then
check the oil level and correct it if
necessary.
EAU04945
Coolant The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
To check the coolant level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:_
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
Make sure that the motorcycle is
positioned straight up when
checking the coolant level. A slight
tilt to the side can result in a false
reading.

surface and hold it in an upright
position.NOTE:@ When checking and adjusting the drive
chain slack, the motorcycle should be
positioned straight up and there should
be no weight on it. @2. Shift the transmission into the neu-
