w
This shock absorber contains high-
ly pressurized nitrogen gas. Read
and understand the following
information before handling the
shock absorber. The manufacturer
cannot be held responsible for
property damage or personal
injury that may result from
improper handling.
1. Do not tamper with or
attempt to open the cylinder
assembly.
2. Do not subject the shock
absorber to an open flame or
other high heat source. This
may cause the unit to explode
due to excessive gas pressure.
3. Do not deform or damage the
cylinder in any way. Cylinder
damage will result in poor
damping performance.
4. Take your shock absorber to a
Yamaha dealer for any service.

Periodic inspection, adjustment
and lubrication will keep your
motorcycle in the safest and most
efficient condition possible. Safety
is an obligation of the motorcycle
owner. The maintenance and lubri-
cation schedule chart should be
considered strictly as a guide to
general maintenance and lubrica-
tion intervals. YOU MUST TAKE
INTO CONSIDERATION THAT
WEATHER, TERRAIN, GEOGRAPHI-
CAL LOCATIONS, AND A VARIETY
OF INDIVIDUAL USES ALL TEND
TO DEMAND THAT EACH OWNER
ALTER THIS TIME SCHEDULE TO
SHORTER INTERVALS TO MATCH
THE ENVIRONMENT. The most
important points of motorcycle
inspection, adjustment, and lubri-
cation are explained in the follow-
ing pages.1
EAU01175Tool kit
The tool kit is located behind panel
B. (See page 6-7 for panel removal
and installation procedures.)
The tools provided in the owner’s
tool kit are to assist you in the per-
formance of periodic maintenance.
However, some other tools such as
a torque wrench are also necessary
to perform the maintenance cor-
rectly.
The service information included in
this manual is intended to provide
you, the owner, with the necessary
information for completing some
of your own preventive mainte-
nance and minor repairs.

EAU00629Carburetor adjustment
The carburetor is a vital part of the
engine and requires very sophisti-
cated adjustment. Most adjust-
ments should be left to a Yamaha
dealer who has the professional
knowledge and experience to do
so. However, the following may be
serviced by the owner as part of
routine maintenance.
EC000094
cC
The carburetor was set at the
Yamaha factory after many tests. If
the settings are changed, poor
engine performance and damage
may result.
EAU01168Idle speed adjustment
NOTE:
A diagnostic tachometer must be
used for this procedure.
1. Attach the tachometer. Start
the engine and warm it up for
a few minutes at approximate-
ly 1,000 to 2,000 r/min.
Occasionally rev the engine to
4,000 to 5,000 r/min. The
engine is warm when it quickly
responds to the throttle.

speed.
NOTE:
If the specified idle speed cannot
be obtained by performing the
above adjustment, consult a
Yamaha dealer.
Standard idle speed:

Throttle cable free play
inspection
There should be a free play of 2 ~ 5
mm at the throttle grip. If the free
play is incorrect, ask a Yamaha
dealer to make this adjustment.
EAU00636Cam chain adjustment
The cam chain becomes loose with
use, resulting in improper valve
timing and engine noise. To pre-
vent this, the cam chain tensioner
must be adjusted regularly. This
adjustment, however, should be
left to a professional Yamaha ser-
vice technician.
EAU00637
Valve clearance adjustment
The correct valve clearance
changes with use, resulting in
improper fuel/air supply or engine
noise. To prevent this, the valve
clearance must be adjusted regu-
larly. This adjustment however,
should be left to a professional
Yamaha service technician.

Proper loading of your motorcycle
is important for several character-
istics of your motorcycle; such as
handling, braking, performance
and safety. Do not carry loosely
packed items that can shift.
Securely pack your heaviest items
close to the center of the motorcy-
cle, and distribute the weight
evenly from side to side. Check the
condition and pressure of your
tires. NEVER OVERLOAD YOUR
MOTORCYCLE. Make sure the
total weight of the cargo, rider,
passenger, and accessories (fair-
ing, saddlebags, etc. if approved
for this model) does not exceed
the maximum load of the motorcy-
cle. Operation of an overloaded
motorcycle could cause tire dam-
age, an accident, or even injury.

ger, and accessories.

EAU00668Tires
To ensure maximum performance,
long service, and safe operation,
note the following:
1. Tire air pressure
Always check and adjust the
tire pressure before operating
the motorcycle.
EW000082
w
Tire inflation pressure should be
checked and adjusted when the
temperature of the tire equals the
ambient air temperature. Tire infla-
tion pressure must be adjusted
according to total weight of cargo,
rider, passenger, and accessories
(fairing, saddlebags, etc. if
approved for this model), and vehi-
cle speed.

EAU00685Wheels
To ensure maximum performance,
long service, and safe operation,
note the following:
1. Always inspect the wheels
before a ride. Check for cracks,
bends or warpage of the
wheel. Be sure the spokes are
tight and undamaged. If any
abnormal condition exists in a
wheel, consult a Yamaha deal-
er. Do not attempt even small
repairs to the wheel. If a wheel
is deformed or cracked, it must
be replaced.
2. Tires and wheels should be
balanced whenever either one
is changed or replaced. Failure
to have a wheel balanced can
result in poor performance,
adverse handling characteris-
tics, and shortened tire life.3. Ride at moderate speeds after
changing a tire since the tire
surface must first be broken in
for it to develop its optimal
characteristics.
EAU00680
w
1. It is dangerous to ride with a
worn-out tire. When a tire
tread begins to show lines,
have a Yamaha dealer replace
the tire immediately. Brakes,
tires, and related wheel parts
replacement should also be
left to a Yamaha dealer.
2. Patching a punctured tube is
not recommended. If it is
absolutely necessary to do so,
use great care and replace the
tube as soon as possible with
a good quality replacement.
