TIP
This model is equipped with a lean an-
gle sensor to stop the engine in case
of a turnover. In this case, the multi-
function display indicates error code
30, but this is not a malfunction. Turn
the key to "OFF" and then to "ON" to
clear the error code. Failing to do so
will prevent the engine from starting
even though the engine will crank
when pushing the start switch.

●Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure de-
scribed on page 4-18.

PERIODIC MAINTENANCE AND ADJUSTMENT
EAU17241
Periodic inspection, adjustment, and
lubrication will keep your vehicle in the
safest and most efficient condition
possible. Safety is an obligation of the
vehicle owner/operator. The most im-
portant points of vehicle inspection,
adjustment, and lubrication are ex-
plained on the following pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a gen-
eral guide under normal riding condi-
tions. However, depending on the
weather, terrain, geographical loca-
tion, and individual use, the mainte-
nance intervals may need to be short-
ened.
EWA10321
WARNING0
Failure to properly maintain the ve-
hicle or performing maintenance
activities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle
service, have a Yamaha dealer per-
form service.
EAU17391

EWA15121
WARNING0
Turn off the engine when perform-
ing maintenance unless otherwise
specified.
A running engine has moving parts
that can catch on body parts or

can lead to eye injury, burns, fire, or
carbon monoxide poisoning - pos-
sibly leading to death. See page 2-2
for more information about carbon
monoxide.

TIP
The coolant should be between the
minimum and maximum level marks.
1. Coolant reservoir
2. Maximum level mark
3. Minimum level mark
4. Reservoir cap
3. If the coolant is at or below the
minimum level mark, remove pan-
el E (See page 7-7.), remove the
reservoir cap, add coolant to the
maximum level mark, and then in-
stall the reservoir cap and the
panel. WARNING! Remove only
the coolant reservoir cap. Nev-
er attempt to remove the radia-
tor cap when the engine is hot.
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
is harmful to the engine. If wa-
ter has been used instead of
coolant, replace it with coolant
as soon as possible, otherwise
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 an-
tifreeze content of the coolant
as soon as possible, otherwise
the effectiveness of the coolant
will be reduced.
Coolant reservoir capacity
(up to the maximum level mark):
0.50 L (0.52 US qt) (0.44 Imp.
EAU33031
Changing the coolant
The coolant must be changed at the
intervals specified in the periodic
maintenance and lubrication chart.
Have a Yamaha dealer change the
coolant. WARNING! Never attempt
to remove the radiator cap when
the engine is hot.

Tires
To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points regard-
ing the specified tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
EWA10501
WARNING0
Operation of this vehicle with im-
proper tire pressure may cause se-
vere injury or death from loss of
control.
●The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the tempera-
ture of the tires equals the am-
bient temperature).
●The tire air pressure must be
adjusted in accordance with
the riding speed and with the
total weight of rider, passenger,
cargo, and accessories ap-
proved for this model.
EAU21382
Checking the throttle cable
free play
1. Throttle cable free play
The throttle cable free play should
measure 3.0-5.0 mm (0.12-0.20 in) at
the throttle grip. Periodically check the
throttle cable free play and, if neces-
sary, have a Yamaha dealer adjust it.
EAU21401
Valve clearance
The valve clearance changes with
use, resulting in improper air-fuel mix-
ture and/or engine noise. To prevent
this from occurring, the valve clear-
ance must be adjusted by a Yamaha
dealer at the intervals specified in the
periodic maintenance and lubrication
chart.
