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 ama ged . The spark plu g cap may
b e difficult to remove b ecause 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.

En gine oil an d oil filter car-
tri dg e
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 a level surfa- ce and hold it in an upright posi-
tion. 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.
4. Remove the engine oil dipstick and wipe it clean, insert it back
into the hole (without screwing it
in), and then remove it again to
check the oil level.
TIP
The engine oil should be between the
minimum and maximum level marks.
5. Check the dipstick O-ring fordamage, and replace it if neces-
sary.
6. If the engine oil is at or below the minimum level mark, remove the
engine oil filler cap, and then add
sufficient oil of the recommended
type to raise it to the correct level.
7. Check the filler cap O-ring for damage, and replace it if neces-
sary.
8. Insert and tighten the engine oil dipstick, and then install and tight-
en the oil filler cap.
To chan ge the en gine oil (with or
without oil filter cartri dge replace-
ment) 1. Place the vehicle on a level surfa- ce.
2. Remove cowlings A and B. (See page 7-7.)
3. Start the engine, warm it up for several minutes, and then turn it
off.
4. Place an oil pan under the engine to collect the used oil.

gasket to drain the oil from the
crankcase.
TIP
Skip steps 6–12 if the oil filter cartridge
is not being replaced.
6. Remove the shift arm bolt, andthen pull the shift arm off the shift
shaft.
TIP
If necessary, disconnect the shift
switch and connecting rod by loosen-
ing the bottom nut.
7. Remove the fuel tank overflowhose from the guides.
8. Remove the oil filter cartridge with an oil filter wrench.
TIP
An oil filter wrench is available at a
Yamaha dealer.
9. Apply a thin coat of clean engine oil to the O-ring of the new oil filter
cartridge.

TIP
Make sure that the O-ring is properly
seated.
10. Install the new oil filter cartridge
with an oil filter wrench, and then
tighten it to the specified torque
with a torque wrench.
11. Install the fuel tank overflow hose into the guides, then place them in
their original position.
12. Install the shift arm by aligning the slot in the shift arm with the mark
on the shift shaft and installing the
shift arm bolt, then tightening it to
the specified torque. NOTICE: Be
sure to ali gn the slot an d mark to ensure proper shiftin
g. If the
slot an d mark are not ali gne d,
the shift arm will not move cor-
rectly an d you may not be ab le
to shift up or down.

TIP
Be sure to wipe off spilled oil on any
parts after the engine and exhaust sys-
tem have cooled down.
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.
15. Check the filler cap O-ring for damage, and replace it if neces-
sary.
16. Install and tighten the oil filler cap.
17. 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 dealer check
the vehicle.
18. Turn the engine off, and then check the oil level and correct it if
necessary.
19. Check the dipstick O-ring for damage, and replace it if neces-
sary.
20. Install the cowlings.

Coolant
The coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals specified in
the periodic maintenance chart.
TIP
If genuine Yamaha coolant is not avail-
able, use an ethylene glycol antifreeze
containing corrosion inhibitors for alu-
minum engines and mix with distilled
water at a 1:1 ratio.
EAU3908BTo check the coolant level
Since the coolant level varies with en-
gine temperature, check when the en-
gine is cold.
1. Park the vehicle on a level surface.
2. With the vehicle in an upright posi- tion, look at the coolant level in the
reservoir. 3. If the coolant is at or below the mi-
nimum level mark, remove panel B
to access the coolant reservoir.
(See page 7-7.)
4. Remove the coolant reservoir cap. WARNING! Remove only the
coolant reservoir cap. Never at-
tempt to remove the ra diator
cap when the en gine is hot.
[EWA15162]
5. Add coolant to the maximum level
mark. NOTICE: If coolant is not
availa ble, use distille d 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.
[ECA10473]
6. Install the coolant reservoir cap.
7. Install the panel.
Recommen ded coolant:
YAMALUBE coolant
Coolant quantity: Coolant reservoir (max level mark):0.25 L (0.26 US qt, 0.22 Imp.qt)
