Adjusting the throttle cable
free play
Throttle cable free play, adjusting
The throttle cable free play should
measure 3–5 mm at the throttle grip.
Periodically check the throttle cable
free play and, if necessary, have a
Yamaha dealer adjust it.

Adjusting the valve
clearance
Valve clearance, adjusting
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.

Tires
Tires
To maximize the performance, dura-
bility, and safe operation of your
motorcycle, note the following points
regarding the specified tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
EW000082
w8The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the tempera-
ture of the tires equals the
ambient temperature).
8The tire air pressure must be
adjusted in accordance with
the riding speed and with the
total weight of rider, passen-
ger, cargo, and accessories
approved for this model.

wBecause loading has an enormous
impact on the handling, braking,
performance and safety character-
istics of your motorcycle, you
should keep the following precau-
tions in mind.
8NEVER OVERLOAD THE
MOTORCYCLE! Operation of
an overloaded motorcycle may
result in tire damage, loss of
control, or severe injury. Make
sure that the total weight of
rider, passenger, cargo, and
accessories does not exceed
the specified maximum load
for the vehicle.
8Do not carry along loosely
packed items, which can shift
during a ride.
8Securely pack the heaviest
items close to the center of the
motorcycle and distribute the
weight evenly on both sides.8Adjust the suspension and tire
air pressure with regard to the
load.
8Check the tire condition and
air pressure before each ride.

6 Tire inspection
The tires must be checked before
each ride. If the center tread depth
reaches the specified limit, if the tire
has a nail or glass fragments in it, or
if the sidewall is cracked, have a
Yamaha dealer replace the tire imme-
diately.
NOTE:
The tire tread depth limits may differ
from country to country. Always com-
ply with the local regulations.
Tire information
This motorcycle is equipped with tube
tires.
EW000078
w8The front and rear tires should
be of the same make and
design, otherwise the handling
characteristics of the motorcy-
cle cannot be guaranteed.

w8Have a Yamaha dealer replace
excessively worn tires.
Besides being illegal, operat-
ing the motorcycle with exces-
sively worn tires decreases
riding stability and can lead to
loss of control.
8The replacement of all wheel-
and brake-related parts,
including the tires, should be
left to a Yamaha dealer, who
has the necessary profession-
al knowledge and experience.
8It is not recommended to
patch a punctured tube. If
unavoidable, however, patch
the tube very carefully and
replace it as soon as possible
with a high-quality product.

MOTORCYCLE CARE AND STORAGE
7 After cleaning
1. Dry the motorcycle with a
chamois or an absorbing cloth.
2. Immediately dry the drive chain
and lubricate it to prevent it from
rusting.
3. Use a chrome polish to shine
chrome, aluminum and stainless-
steel parts, including the exhaust
system. (Even the thermally
induced discoloring of stainless-
steel exhaust systems can be
removed through polishing.)
4. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all metal, includ-
ing chrome- and nickel-plated,
surfaces.
5. Use spray oil as a universal
cleaner to remove any remaining
dirt.
6. Touch up minor paint damage
caused by stones, etc.7. Wax all painted surfaces.
8. Let the motorcycle dry complete-
ly before storing or covering it.
EWA00001
w8Make sure that there is no oil
or wax on the brakes or tires.
If necessary, clean the brake
discs and brake linings with a
regular brake disc cleaner or
acetone, and wash the tires
with warm water and a mild
detergent.
8Before operating the motorcy-
cle test its braking perfor-
mance and cornering behav-
ior.
ECA00013
cC8Apply spray oil and wax spar-
ingly and make sure to wipe
off any excess.
8Never apply oil or wax to any
rubber and plastic parts, but
treat them with a suitable care
product.
8Avoid using abrasive polish-
ing compounds as they will
wear away the paint.NOTE:
Consult a Yamaha dealer for advice
on what products to use.

MOTORCYCLE CARE AND STORAGE
7 7. Check and, if necessary, correct
the tire air pressure, and then lift
the motorcycle so that both of its
wheels are off the ground.
Alternatively, turn the wheels a
little every month in order to pre-
vent the tires from becoming
degraded in one spot.
8. Cover the muffler outlets with
plastic bags to prevent moisture
from entering them.
9. Remove the battery and fully
charge it. Store it in a cool, dry
place and charge it once a
month. Do not store the battery
in an excessively cold or warm
place (less than 0 °C or more
than 30 °C). For more informa-
tion on storing the battery, see
page 6-32.
NOTE:
Make any necessary repairs before
storing the motorcycle.
