Starting the engine
EAU15951
Read the Owner’s Manual carefully to
become familiar with all controls. If there
is a control or function you do not un-
derstand, ask your Yamaha dealer.
EWA10271
WARNING
Failure to familiarize yourself with
the controls can lead to loss of con-
trol, which could cause an accident
or injury.
EAU45310
TIP
This model is equipped with a lean angle
sensor to stop the engine in case of a
turnover. To start the engine after a turn-
over, be sure to turn the main switch to
“OFF” and then to “ON”. Failing to do so
will prevent the engine from starting
even though the engine will crank when
pushing the start switch.
EAUT2251
Starting the engine
ECA10250
NOTICESee page 5-3 for engine break-in in-
structions prior to operating the ve-
hicle for the first time.1. Turn the key to “ON”.
ECAT1070
NOTICEThe engine trouble warning light and
coolant temperature warning light
should come on for a few seconds,
then go off. If these warning lights do
not go off, have a Yamaha dealer check
their electrical circuits.2. Close the throttle completely.
3. Start the engine by pushing the
start switch while applying the front
or rear brake.
NOTICE:
For maxi-
mum engine life, never acceler-
ate hard when the engine is
cold!
[ECA11041]
If the engine does not start, release
the start switch, wait a few sec-
onds, and then try again. Each
starting attempt should be as short
as possible to preserve the battery.
Do not crank the engine more than
5 seconds on any one attempt. If
the engine does not start with the
starter motor, try using the
kickstar ter.

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. Coolant
EAUT1523
To check the coolant level
The coolant level should be checked as
follows before each ride. In addition, the
coolant must be changed at the inter-
vals specified in the periodic mainte-
nance and lubrication chart.
1. Place the vehicle on the
centerstand.TIP
8The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
8Make 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.TIP
The coolant should be between the mini-
mum and maximum level marks.ZAUM00**

1. Coolant reservoir cap3. If the coolant is at or below the mini-
mum level mark, remove panel B
and the reservoir cap. (See page 6-
5.) WARNING! Remove only the
coolant reservoir cap. Never at-
tempt to remove the radiator cap
when the engine is hot.
[EWA15161]
4. Add coolant or distilled water to
raise the coolant to the maximum
level mark, and install the coolant
reservoir cap and the panel.
NOTICE:
If coolant is not avail-
able, use distilled water or soft
tap water instead. Do not use hard
water or salt water since it isharmful to the engine. If water
has been used instead of cool-
ant, replace it with coolant as
soon as possible, otherwise the
cooling system will not be pro-
tected against frost and corro-
sion. If water has been added to
the coolant, have a Yamaha
dealer check the antifreeze con-
tent of the coolant as soon as
possible, otherwise the effective-
ness of the coolant will be
reduced.

mentThe air filter element must be replaced
and the check hoses must be cleaned
at the intervals specified in the periodic

WARNING
8 88 8
8Do 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.
8 88 8
8Place 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 hissing sound has stopped, press down on the cap
while turning it counterclockwise, and then remove the cap.TIP
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.
