To change the coolant
1. Place the motorcycle on a level
surface and let the engine cool if
necessary.
2. Remove cowlings A and B, and
panel A. (See pages 6-5 and 6-6
for cowling and panel removal and
installation procedures.)
3. Place a container under the en-
gine to collect the used coolant.4. Remove the radiator cap and cool-
ant reservoir cap.

WARNING
@ Never attempt to remove the radia-
tor cap when the engine is hot. @5. Remove the coolant reservoir
bolts and the clutch cable holder
bolt, and then turn the coolant res-
ervoir upside-down to empty it.
6. Install the coolant reservoir and
the clutch cable holder by install-
ing the bolts.7. Remove the coolant drain bolt to

6 8. Loosen the radiator hose clamp
screw located at the left side of the
engine, and then pull off the hose
to drain the radiator.
9. After the coolant is completely
drained, thoroughly flush the cool-
ing system with clean tap water.
10. Install the coolant drain bolt, and
then tighten it to the specified
torque.
NOTE:@ Check the washer for damage and re-
place it if necessary. @
11. Connect the radiator hose, and
then tighten the clamp screw.
12. Pour the specified amount of rec-
ommended coolant into the radia-
tor and reservoir.
EC000080
CAUTION:@ l
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.
l
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.
l
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.
@13. Install the radiator cap, start the
engine, let it idle for several min-
utes, and then turn it off.

614. 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.
15. Check the coolant level in the res-
ervoir. If necessary, remove the
coolant reservoir cap, add coolant
to the maximum level mark, and
then install the cap.
16. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
17. Install the cowlings and the panel.

Cleaning the air filter element The air filter element should be cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
Clean the air filter element more fre-
quently if you are riding in unusually
wet or dusty areas.
1. Remove the rider seat. (See page
3-14 for rider seat removal and in-
stallation procedures.)
2. Remove the bolt at the front of the
fuel tank and loosen the bolt at the
rear.3. Lift the front of the fuel tank, and
then tilt it back and away from the
air filter case. (Do not disconnect
the fuel hoses!)1. Bolt (front)

EW000070
WARNING
@ l
Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.
l
After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the hiss-
ing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
@NOTE:@ If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended coolant
as soon as possible. @
Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See NOTE.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
There is
leakage.
There is
no leakage.
