Engine oil and oil filter car-
tridge 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 vehicle on a level sur-
face 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.TIPThe 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
engine oil filler cap, and then add
sufficient 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. Place the vehicle on a level sur-
face.
2. Remove cowling A. (See page
6-8.)
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.
5. Remove the engine oil filler cap,
the engine oil drain bolt and its
gasket to drain the oil from the
crankcase.1. Engine oil dipstick

TIPSkip steps 6–12 if the oil filter cartridge
is not being replaced.6. Remove the shift arm by removing
the bolt and pulling it off the shift
shaft.
7. Remove the fuel tank breath-
er/overflow hoses from the guides.8. Remove the oil filter cartridge with
an oil filter wrench.
TIPAn 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.TIPMake 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.

flow hoses into the guides, then
place them in their original posi-
tion.
12. Install the shift arm by aligning the
match mark on the shift arm with
the match mark on the shift shaft
and installing the bolt, then tighten-
ing it to the specified torque.
NOTICE: Be sure to align the
match marks to ensure proper
shifting. If the match marks are
not aligned, the shift arm willnot move correctly and you may
not be able to shift up or down.

13. Install the engine oil drain bolt and
its new gasket, and then tighten
the bolt to the specified torque.14. Refill with the specified amount of
the recommended engine oil, and
then install and tighten the oil filler
cap.
TIPBe sure to wipe off spilled oil on any
parts after the engine and exhaust sys-
tem have cooled down.NOTICE

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

6addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.


Make sure that no foreign mate-
rial enters the crankcase.
15. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.TIPAfter the engine is started, the engine
oil level warning light should go off if the
oil level is sufficient.NOTICE
ECA10401
If the oil level warning light flickers
or remains on even if the oil level is
correct, immediately turn the engine
off and have a Yamaha dealer check
the vehicle.16. Turn the engine off, and then
check the oil level and correct it if
necessary.
17. Install the cowling.

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.
EAU39087
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.TIP

The coolant level must be checked
on a cold engine since the level
varies with engine temperature.


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 cool-
ant reservoir.TIPThe coolant should be between the
minimum and maximum level marks.
3. If the coolant is at or below the
minimum level mark, remove pan-
el B to access the coolant reser-
voir. (See page 6-8.)
4. Remove the coolant reservoir cap,
add coolant to the maximum level
mark, and then install the reservoir
cap. WARNING! Remove only
the coolant reservoir cap. Never
attempt to remove the radiator
cap when the engine is hot.
[EWA15161]
NOTICE: If coolant is not
available, use distilled water or
soft tap water instead. Do not
use hard water or salt water
since it is harmful to the engine.

6 If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the cooling system will not
be protected against frost and
corrosion. If water has been
added to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possible, otherwise the
effectiveness of the coolant will
be reduced.
[ECA10472]
5. Install the panel.
EAU39004
To change the coolant
1. Place the vehicle on a level sur-
face and let the engine cool if nec-
essary.
2. Remove cowlings B and C. (See
page 6-8.)
3. Place a container under the engine
to collect the used coolant.
4. Remove the radiator cap.
WARNING! Never attempt to re-
move the radiator cap when the
engine is hot.
[EWA10381]
5. Remove the coolant drain bolt and
its gasket to drain the cooling sys-
tem.6. Move the hose clamp in the direc-
tion shown, and then disconnect
the radiator hose to drain the radi-
ator.
7. Remove the coolant reservoir by
removing the bolts.
8. Remove the coolant reservoir cap,
and then turn the coolant reservoir
upside down to empty it.

into the radiator until it is full.
15. Install the radiator cap, start the
engine, let it idle for several min-
utes, and then turn it off.
16. Remove the radiator cap to check
the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radia-
tor, and then install the radiator
cap.17. Start the engine, and then check
