ly, and then remain on until the en-
gine is started.
NOTICE

If a warning or indicator light does
not work as described above, see
page 4-6 for the corresponding
warning and indicator light circuitcheck.
2. Shift the transmission into the neu- tral position. The neutral indicator
light should come on. If not, ask a
Yamaha dealer to check the elec-
trical circuit.
3. Start the engine by pushing the start switch.
If the engine does not start within 5
seconds of pressing the start
switch, wait 10 seconds before
pressing the switch again to allow
the battery voltage to restore.NOTICE

For maximum engine life, never ac- celerate hard when the engine is
cold!

amount of engine power available for
starting off, accelerating, climbing hills,
etc.
The gear positions are shown in the il-
lustration.TIPFor speedy upshifts, turn on the quick
shift system. See QSS on page 4-17 formore information.NOTICE

TIPBe sure to wipe off spilled oil on any
parts after the engine and exhaust sys-tem have cooled down.NOTICE
ECA11621

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.
10. 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 oil pres-
sure and coolant temperature warning
light should go off if the oil level is suffi-cient.NOTICE
ECA22490
If the oil pressure and coolant tem-
perature warning light flickers or re-
mains on even if the oil level is
correct, immediately turn the engine
off and have a Yamaha dealer checkthe vehicle.
11. Turn the engine off, wait a few min- utes until the oil settles, and then
check the oil level and correct it if
necessary.
12. Install the cowling and panel.
EAU20071
CoolantThe 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.
EAU66510
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 theside can result in a false reading.
2. Check the coolant level in the cool- ant reservoir.
TIPThe coolant should be between theminimum and maximum level marks.
Recommended engine oil:Full synthetic SAE 10W-40 or
15W-50
Oil quantity:
Without oil filter cartridge replace-
ment: 3.90 L (4.12 US qt, 3.43 Imp.qt)
With oil filter cartridge replacement: 4.10 L (4.33 US qt, 3.61 Imp.qt)

minimum level mark, remove cowl-
ing B. (See page 7-8.)
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.
[EWA15162]
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.
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.
[ECA10473]
5. Install the cowling.
EAU66520
To change the coolant
1. Place the vehicle on a level sur- face and let the engine cool if nec-
essary.
2. Remove cowling B and panel D. (See page 7-8.)
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.

tem.

drained, thoroughly flush the cool-
ing system with clean tap water.
9. Install the coolant reservoir by in- stalling the bolts.
10. Install the coolant drain bolt and its new gasket, and then tighten the
bolt to the specified torque.
11. Pour the specified amount of the recommended coolant into the ra-
diator and reservoir. 12. Install the coolant reservoir cap.

WARNING
EWAT1041

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.

Place a thick rag, like a towel, over the radiator cap, and then slowly rotate the cap counterclockwise to the de-
tent to allow any residual pressure to escape. When the hissing sound has stopped, press down on the capwhile turning it counterclockwise, and then remove the cap.
TIPIf coolant is not available, tap water can be temporarily
used instead, provided that it is changed to the recommended coolantas 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 TIP.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
