8In 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
specification of “CD” or oils of
a higher quality than specified.
In addition, do not use oils
labeled “ENERGY CONSERV-
ING II” or higher.
8Make sure that no foreign
material 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.2. Check the coolant level in the
coolant reservoir.
NOTE:
The coolant should be between the
minimum and maximum level marks.

CoolantCoolantThe coolant level should be checked
before each ride. In addition, the
coolant must be changed at the inter-
vals specified in the periodic mainte-
nance and lubrication chart.
To check the coolant level
Checking1. Place the motorcycle on the cen-
terstand.
NOTE:
8The coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
8Make 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.

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.

Never attempt to remove the radia-

8The radiator fan is automatically
switched on or off according to
the coolant temperature in the
radiator.
8If the engine overheats, see
page 6-45 for further instructions.

8If 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.
8If water has been used instead
of coolant, replace it with
coolant as soon as possible,
otherwise the engine may not
be sufficiently cooled and the
cooling system will not be pro-
tected against frost and corro-
sion.
8If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possi-
ble, otherwise the effective-
ness of the coolant will be
reduced.

(up to the maximum level mark):

To change the coolantChanging1. Place the motorcycle on a level
surface and let the engine cool if
necessary.
2. Remove the seat. (See page
3-13 for seat removal and instal-
lation 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
hoses!)
5. Place a container under the
engine to collect the used
coolant.7. Remove the coolant drain bolts
to drain the cooling system.

and away from the motorcycle.
10. Drain the remaining coolant from
the coolant reservoir by opening
the cap, then turning the reser-
voir upside down.
11. Install the coolant reservoir by
placing it in the original position,
then installing the bolt.
12. After the coolant is completely
drained, thoroughly flush the
cooling system with clean tap
water.

8Before 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.
8Make sure that the fuel hoses
are properly connected and
routed, and not pinched.
8Be sure to place the fuel tank
breather hose in the original
position.
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 cool-
ing system. 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 suffi-
cient coolant until it reaches the
top of the radiator, and then
install the radiator cap and the
cap retaining bolt.
17. Check the coolant level in the
reservoir. If necessary, remove
the coolant reservoir cap, add
coolant to the maximum level
mark, and then install the cap.
18. Install the fuel tank.
