Make sure that the fuel hoses and
vacuum hose are properly con-
nected, in place and not pinched. If
a hose is damaged, be sure to
replace it.
EAU00629Carburetor adjustment
The carburetor is a vital part of the
engine and requires very sophisticat-
ed adjustment. Most adjustments
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 mainte-
nance.
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.

EAU00632Idle speed adjustment
1. Start the engine and warm it up
for a few minutes at approxi-
mately 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.
2. Set the idle to the specified
engine speed by adjusting the
throttle stop screw. Turn the
screw in direction ato increase
engine speed and in direction b
to decrease engine speed.

EAU00647Tires
To ensure maximum performance,
long service, and safe operation, note
the following:
Tire air pressure
Always check and adjust the tire
pressure before operating the motor-
cycle.
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.

and accessories. Maximum load*180 kg

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 even-
ly from side to side. Properly
adjust the suspension for your
load, and check the condition and
pressure of your tires. NEVER
OVERLOAD YOUR MOTORCYCLE.
Make sure the total weight of the
cargo, rider, passenger, and
accessories (fairing, saddlebags,
etc. if approved for this model)
does not exceed the maximum
load of the motorcycle. Operation
of an overloaded motorcycle could
cause tire damage, an accident, or
even injury.

9 Tire inspection
Always check the tires before operat-
ing the motorcycle. If center tread
depth reaches the limit as shown, if
the tire has a nail or glass fragments
in it, or if the side wall is cracked,
contact a Yamaha dealer immediate-
ly and have the tire replaced.

Operating the motorcycle with
excessively worn tires decrease
riding stability and can lead to loss
of control. Have excessively worn
tires replaced by a Yamaha dealer
immediately. Brakes, tires, and
related wheel parts replacement
should be left to a Yamaha Service
Technician.

EAU00687Wheels
To ensure maximum performance,
long service, and safe operation, note
the following:
8Always inspect the wheels
before a ride. Check for cracks,
bends, or warpage of the wheels.
If any abnormal condition exists
in a wheel, consult a Yamaha
dealer. Do not attempt even
small repairs to the wheel. If a
wheel is deformed or cracked, it
must be replaced.
8Tires and wheels should be bal-
anced whenever either one is
changed or replaced. Failure to
have a wheel balanced can
result in poor performance,
adverse handling characteristics,
and shortened tire life.
8Ride at moderate speeds after
changing a tire since the tire sur-
face must first be broken in for it
to develop its optimal character-
istics.
