2011 YAMAHA XT660Z warning

EAU20070
Coolant
The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU20253
To check the coolant level
1. Place the vehicle on a level surface
and hold it in an upright position.
TIP
The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
Make sure that the vehicle is
positioned 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
coolant reservoir.
TIP
The coolant should be between the
minimum and maximum level marks.
1. Coolant reservoir
2. Maximum level mark
3. Minimum level mark
4. Coolant reservoir cap
3. If the coolant is at or below the
minimum level mark, remove
panel E (See page 6-8). , remove
the reservoir cap, add coolant to
the maximum level mark, and
then install the reservoir cap and
the panel. WARNING! Remove
only the coolant reservoir cap.
Never attempt to remove the
radiator cap when the engine is
hot.
[EWA15161]
NOTICE: If coolant is not avai-
lable, 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 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 anti-
freeze content of the coolant
as soon as possible, otherwise
the effectiveness of the coolant
will be reduced.
[ECA10472]
Coolant reservoir capacity (up to
the maximum level mark):
0.50 L (0.53 US qt, 0.44 Imp.qt)

tion, the air filter check hose must be
frequently checked and cleaned if
necessary.
To replace the air filter element
1. Remove the seat. (See page
3-16).
2. Remove the air filter case cover
by removing the screws.
1. Air filter case cover

ted without the air filter ele-
ment installed, otherwise the
piston(s) and/or cylinder(s)
may become excessively worn.

1. Throttle grip free play
The throttle cable free play should
measure 3.0–5.0 mm (0.12–0.20 in) at
the inner edge of the throttle grip.
Periodically check the throttle cable
free play and, if necessary, 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 clearan-
ce must be adjusted by a Yamaha
dealer at the intervals specified in the
periodic maintenance and lubrication
chart.
EAU21642
Tires
To maximize the performance, durabi-
lity, and safe operation of your

regarding the specified tires.
Tire air pressure
The tire air pressure should be chec-
ked and, if necessary, adjusted befo-
re each ride.
EWA10503
Operation of this vehicle with
improper tire pressure may
cause severe injury or death
from loss of control.
The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperatu-
re of the tires equals the
ambient 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 appro-
ved for this model.

EWA10570
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
motorcycle with excessively
worn tires decreases riding
stability and can lead to loss of
control.
The replacement of all wheel-
and brake-related parts, inclu-ding the tires, should be left to
a Yamaha dealer, who has the
necessary professional know-
ledge and experience.
It is not recommended to patch
a punctured tube. If unavoida-
ble, however, patch the tube
very carefully and replace it as
soon as possible with a high-
quality product.
EAU21942
Spoke wheelsEWA10610
The wheels on this model are not
designed for use with tubeless
tires. Do not attempt to use tube-
less tires on this model.
To maximize the performance, durabi-
lity, and safe operation of your
motorcycle, note the following points
regarding the specified wheels.
The wheel rims should be chec-
ked for cracks, bends or warpa-
ge, and the spokes for looseness
or damage before each ride. If
any damage is found, have a
Yamaha dealer replace the whe-
el. Do not attempt even the sma-
llest repair to the wheel. A defor-
med or cracked wheel must be
replaced.
The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced.
An unbalanced wheel can result
in poor performance, adverse
handling characteristics, and a
shortened tire life.
