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.NOTE:_ Skip steps 4–6 if the oil filter element is
not being replaced. _

65. Remove and replace the oil filter
element and O-rings.
6. Install the oil filter element cover
by installing the bolts, then tighten-
ing them to the specified torque.
NOTE:_ Make sure that the O-rings are properly
seated. _7. Install the engine oil drain bolts,
and then tighten them to the spec-
ified torques.8. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil filler
cap.

CAUTION:_
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives with
the oil or use oils of a higher
grade than “CD”. 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 idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately 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.

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.
_
2. Check the coolant level in the
coolant reservoir.NOTE:_ The coolant should be between the
minimum and maximum level marks. _
3. If the coolant is at or below the
minimum level mark, remove
panel B (See page 6-6 for panel
removal and installation proce-
dures.), remove the reservoir cap,
add coolant to the maximum level
mark, and then install the reservoir
cap and the panel.

CAUTION:_
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
_ Never attempt to remove the radia-

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
6-44 for further instructions.

To change the coolant
1. Place the motorcycle on a level
surface and let the engine cool if
necessary.
2. Remove the seat. (See page 3-11
for seat removal and installation
procedures.)
3. Remove cowling B and panel B.
(See pages 6-5 and 6-6 for cowl-
ing and panel removal and instal-
lation procedures.)
4. Remove the fuel tank bolts, and
then lift the fuel tank to position it
away from the coolant reservoir.
(Do not disconnect the fuel hos-
es!)
5. Place a container under the en-
gine to collect the used coolant.

WARNING
_
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.
