Adjusting the valve
clearanceThe 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.

TiresTo 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.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.

Changing the brake fluidHave a Yamaha dealer change the
brake fluid at the intervals specified in
the NOTE after the periodic mainte-
nance and lubrication chart. In addi-
tion, have the oil seals of the brake
master cylinder and caliper as well as
the brake hose replaced at the inter-
vals listed below or whenever they
are damaged or leaking.
8Oil seals: Replace every two
years.
8Brake hose: Replace every four
years.2. Shift the transmission into the
neutral position.
3. Move the rear wheel by pushing
the motorcycle to locate the tight-
est portion of the drive chain,
and then measure the drive
chain slack as shown.
4. If the drive chain slack is incor-
rect, adjust it as follows.
a
a. Drive chain slack
EAU00744
Drive chain slackThe drive chain slack should be
checked before each ride and adjust-
ed if necessary.
To check the drive chain slack
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:
When checking and adjusting the
drive chain slack, the motorcycle
should be positioned straight up and
there should be no weight on it.
Drive chain slack:
35–60 mm

cCBe sure to use motor oils that do not contain anti-friction
modifiers. Passenger car motor oils (often labeled “ENERGY
CONSERVING II”) contain anti-friction additives which will
cause clutch and/or starter clutch slippage, resulting in
reduced component life and poor engine performance.
