Checkin g the spark plu gs
The spark plugs are important engine
components, which should be
checked periodically, preferably by a
Yamaha dealer. Since heat and depos- its will cause any spark plug to slowly
erode, they should be removed and
checked in accordance with the peri-
odic maintenance and lubrication
chart. In addition, the condition of the
spark plugs can reveal the condition of
the engine.
The porcelain insulator around the
center electrode of each spark plug
should be a medium-to-light tan (the
ideal color when the vehicle is ridden
normally), and all spark plugs installed
in the engine should have the same
color. If any spark plug shows a dis-
tinctly different color, the engine could
be operating improperly. Do not at-
tempt to diagnose such problems
yourself. Instead, have a Yamaha deal-
er check the vehicle.
If a spark plug shows signs of elec-
trode erosion and excessive carbon or
other deposits, it should be replaced.
Before 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.
TIP
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
specified torque as soon as possible.
NOTICE
ECA10841
Do not use any tools to remove or in-
stall the spark plu
g cap, otherwise
the i gnition coil coupler may get
d amag ed . The spark plu g cap may
b e difficult to remove because the
ru bber seal on the en d of the cap fits
ti g htly. To remove the spark plu g
cap, simply twist it b ack and forth
while pullin g it out; to install it, twist
it back an d forth while pushin g it in.

Canister
This model is equipped with a canister
to prevent the discharging of fuel vapor
into the atmosphere. Before operating
this vehicle, make sure to check the
following:
Check each hose connection.
Check each hose and canister for
cracks or damage. Replace if
damaged.
Make sure that the canister
breather hose is not blocked, and
if necessary, clean it.
Make sure that the canister
breather hose is positioned out-
side of the cowling.

Engine oil an d oil filter car-
tri dge
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 en gine oil level
1. Place the vehicle on the center- stand. A slight tilt to the side can
result in a false reading.
2. Start the engine and warm it up for ten minutes until the engine oil has
reached a normal temperature of
60 °C (140 °F), and then turn the
engine off.
3. Wait a few minutes until the oil set- tles, and then check the oil level
through the engine oil level check
window located at the bottom-
right side of the crankcase.
TIP
The engine oil should be between the
minimum and maximum level marks.

NOTICE
ECA11621
In or der to prevent clutch slip-
pa ge (since the en gine oil also
lu bricates the clutch), do not
mix any chemical add itives. Do
not use oils with a d iesel speci-
fication of “CD” or oils of a hi gh-
er quality than specified . In
a ddition, do not use oils la bele d
“ENERGY CONSERVING II” or
hi gher.
Make sure that no forei gn mate-
rial enters the crankcase.
14. Check the O-ring for damage, and replace it if necessary.
15. Install and tighten the engine oil filler cap.
16. 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.
TIP
After the engine is started, the engine
oil level warning light should go off if
the oil level is sufficient.
NOTICE
ECA10402
If the oil level warnin g li ght flickers
or remains on even if the oil level is
correct, imme diately turn the en gine
off an d have a Yamaha d ealer check
the vehicle.
17. Turn the engine off, wait a few mi- nutes until the oil settles, and then
check the oil level and correct it if
necessary.

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.
EAU40157To check the coolant level
1. Place the vehicle on the center- stand.
TIP
The coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Check the coolant level in the
coolant reservoir.
TIP
The coolant should be between the mi-
nimum and maximum level marks.
3. If the coolant is at or below the mi-nimum level mark, remove the
coolant reservoir cap. WARNING!
Remove only the coolant reser-
voir cap. Never attempt to re-
move the ra diator cap when the
en gine is hot.
[EWA15162]
4. Add coolant or distilled water to
raise the coolant to the maximum
level mark, install the coolant res-
ervoir cap. NOTICE: If coolant is
not availa ble, use d istilled water
or soft tap water instea d. Do not
use har d water or salt water
since it is harmful to the en gine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possi ble, other-
wise the coolin g system will not
b e protecte d a gainst frost an d
corrosion. If water has b een
a dde d to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possi ble, otherwise the
effectiveness of the coolant will
b e red uced.
