and then remove it again to check
the oil level.
NOTE:
The engine oil should be between the
minimum and maximum level marks.
CAUTION:
ECA10010
Do not operate the vehicle until you
know that the engine oil level is suf-
ficient.
WARNING
EWA10360
Never remove the engine oil tank
cap after high-speed operation, oth-
erwise hot engine oil could spout
out and cause damage or injury. Al-
ways let the engine oil cool down
sufficiently before removing the oil
tank cap.
4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
5. Install the oil filler cap.
NOTE:
The engine oil tank is located be-
hind the cylinders.
The engine oil should be between
the minimum and maximum level
marks.
To change the engine oil (with or
without oil filter element 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.
3. Remove the engine oil filler cap
and drain bolts to drain the oil from
the crankcase.

CAUTION:
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.
9. 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.
10. Turn the engine off, and then
check the oil level and correct it if
necessary.
EAU20070
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.
EAU20101
To check the coolant level
1. Place the vehicle on the center-
stand.
NOTE:
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.
NOTE:
The coolant should be between the
minimum and maximum level marks. Recommended engine oil:
See page 8-1.
Oil quantity:
Without oil filter element replace-
ment:
3.80 L (4.02 US qt)
(3.34 Imp.qt)
With oil filter element replace-
ment:
3.90 L (4.12 US qt)
(3.43 Imp.qt)

3. If the coolant is at or below the
minimum level mark, remove pan-
el B (See page 6-5.), remove the
reservoir cap, add coolant to the
maximum level mark, and then in-
stall the reservoir cap and the pan-
el.
CAUTION:
ECA10470
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.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the engine may not be
sufficiently cooled and the cool-ing system will not be protected
against frost and corrosion.
If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness of
the coolant will be reduced.
WARNING
EWA10380
Never attempt to remove the radiator
cap when the engine is hot.
NOTE:
The radiator fan is automatically
switched on or off according to the
coolant temperature in the radia-
tor.
If the engine overheats, see page
6-39 for further instructions.
EAU20450
To change the coolant
1. Place the vehicle on a level sur-
face and let the engine cool if nec-
essary.

placing it in the original position,
then installing the bolt.
12. After the coolant is completely
drained, thoroughly flush the cool-
ing system with clean tap water.

WARNING
EWA11290
Before installing the fuel tank,
make sure that the fuel hoses
are not damaged. If any fuel
hose is damaged, do not start
the engine but have a Yamaha
dealer replace the hose, other-
wise fuel may leak.
Make sure that the fuel hoses
are properly connected and
routed, and not pinched.
Be sure to place the fuel tank
breather hose in the original po-
sition.
19. Install the panel, the cowling, and
the seat.
20. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system. Antifreeze/water mixture ratio:

Replacing the air filter element
The air filter element should be re-
placed at the intervals specified in the
periodic maintenance and lubrication
chart. Replace the air filter element
more frequently if you are riding in un-
usually wet or dusty areas.
1. Remove the seat. (See
page 3-13.)
2. Remove cowlings A and B as well
as panels A and B. (See
page 6-5.)
3. Remove the fuel tank bolts, and
then lift the fuel tank away from the
air filter case.4. Remove the air filter case cover by
removing the screws.
5. Pull the air filter element out.
6. Insert a new air filter element into
the air filter case.
CAUTION:
ECA10480
Make sure that the air filter ele-
ment is properly seated in the
air filter case.
The engine should never be op-
erated without the air filter ele-
ment installed, otherwise the
piston(s) and/or cylinder(s) may
become excessively worn.
7. Install the air filter case cover by in-
stalling the screws.
8. Place the fuel tank in the original
position and install the bolts.
WARNING

Adjusting the engine idling
speed
The engine idling speed must be
checked and, if necessary, adjusted as
follows at the intervals specified in the
periodic maintenance and lubrication
chart.
The engine should be warm before
making this adjustment.
NOTE:
The engine is warm when it quickly re-
sponds to the throttle.
Check the engine idling speed and, if
necessary, adjust it to specification by
turning the throttle stop screw. To in-
crease the engine idling speed, turn the
screw in direction (a). To decrease the
engine idling speed, turn the screw in
direction (b).
NOTE:
If the specified idling speed cannot be
obtained as described above, have a
Yamaha dealer make the adjustment.
