Air filterThe air filter should be cleaned at the
specified intervals. It should be cleaned
more frequently if you are riding in un-
usually wet or dusty areas.
1. Remove the seat.
2. Remove the bolts holding the fuel
tank.
3. Lift the fuel tank upward and posi-
tion it away from the air filter case.
(Do not remove the fuel hoses.)

Support the fuel tank carefully
during this procedure.
l
Do not tilt the fuel tank too
much or pull it too hard because
the fuel hose connections may
become loose causing fuel
leakage.

6. Remove the air filter from its guide
and clean it with solvent. After
cleaning, squeeze the air filter to
remove the remaining solvent.7. Apply recommended oil to the en-
tire surface of the filter and
squeeze out the excess oil. The air
filter should be wet but not drip-
ping.

CAUTION:@ l
Make sure the air filter is prop-
erly seated in the air filter case.

The engine should never be run
without the air filter installed.
Excessive piston and/or cylin-
der wear may result.

Air vent hoseIf dust or water collects in this hose, re-
move the hose and clean it.

Air intake ductCheck that the screen of the intake
duct is not blocked. Clean the screen if
necessary.

Carburetor adjustmentThe carburetors are important parts of
the engine and require very sophisti-
cated adjustment. Most adjustments
should be left to a Yamaha dealer who
has the professional knowledge and
experience to do so. However, the idle
speed may be adjusted by the owner
as part of routine maintenance.
EC000095
CAUTION:@ The carburetors were set at the
Yamaha factory after many tests. If
they are changed, poor engine per-
formance and damage may result. @

Idle speed adjustment1. Start the engine and warm it up for
a few minutes at approximately
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 di-
rection a
to increase engine
speed and in direction b
to de-
crease engine speed.
NOTE:@ If the specified idle speed cannot be
obtained by performing the above ad-
justment, consult a Yamaha dealer. @

Throttle cable free play
inspectionThere should be a free play of 3 ~
7 mm at the throttle grip. If the free play
is incorrect, ask a Yamaha dealer to
make this adjustment.

Valve clearance adjustmentThe correct valve clearance changes
with use, resulting in improper fuel/air
supply or engine noise. To prevent this,
the valve clearance must be adjusted
regularly. This adjustment however,
should be left to a professional
Yamaha service technician.

TiresTo ensure maximum performance,
long service and safe operation, note
the following:
Tire air pressure
Always check and adjust the tire pres-
sure before operating the motorcycle.
EW000082
WARNING
@ 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 ac-
cording to total weight of cargo,
rider, passenger, and accessories
(fairing, saddlebags, etc. if approved
for this model), and vehicle speed. @

WARNING
@ Proper loading of your motorcycle
is important for several characteris-
tics 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 motorcycle, and dis-
tribute the weight evenly from side
to side. Properly adjust the suspen-
sion for your load, and check the
condition and pressure of your tires.
NEVER OVERLOAD YOUR MOTOR-
CYCLE. 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 over-
loaded motorcycle could cause tire
damage, an accident, or even injury. @
Tire inspection
Always check the tires before operating
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 immediately and have
the tire replaced.
EW000095
WA R N I N G
@ Operating the motorcycle with ex-
cessively worn tires decrease riding
stability and can lead to loss of con-
trol. Have excessively worn tires re-
placed by a Yamaha dealer
immediately. Brakes, tires, and relat-
ed wheel parts replacement should
be left to a Yamaha Service Techni-
cian. @CE-26ENOTE:@ These limits may be different by regula-
tion from country to country. If so, con-
form to the limits specified by the
regulations of your own country. @

WARNING
@ l
After extensive tests, the tires
mentioned below have been ap-
proved by Yamaha Motor Co.,
Ltd. for this model. No guaran-
tee for handling characteristics
can be given if tire combina-
tions other than what is ap-
proved are used on this
motorcycle. The front and rear
tires should be of the same
manufacture and design.
l
The use of tire valves and valve
cores other than listed below
could cause tire deflation dur-
ing extreme high speed riding.
Always use genuine parts or
their equivalent for replace-
ment.
l
Be sure to install the valve caps
securely, as these are important
to prevent air pressure leakage
during extreme high speed
riding.

WARNING
@ This motorcycle is fitted with super
high-speed running tires. The fol-
lowing points must be observed in
order for you to make fully effective
use of these tires.l
Never fail to use the specified
tires in tire replacement. Other
tires may have a danger of
bursting at super high-speeds.
l
New tires have a relatively low
grip on the road surface until
they have been slightly worn.
Therefore, approximately 100 km
should be traveled at normal
speed before any high-speed
riding is done.
l
Before any high-speed runs, the
tires should be warmed-up suf-
ficiently.
l
Always inflate to the correct tire
pressure according to the oper-
ating conditions.
@
EAU00687
WheelsTo ensure maximum performance,
long service, and safe operation, note
the following:l
Always inspect the wheels before
a ride. Check for cracks, bends, or
warpage of the wheels. If any ab-
normal 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.
l
Tires 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 han-
dling characteristics, and short-
ened tire life.
l
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be broken in for it to
develop its optimal characteristics.
