CAUTION:@ Do not use any type of tools to re-
move or install the cap as the igni-
tion coil coupler may get damaged.
The spark plug cap may be difficult
to remove because a rubber seal on
the end of the cap is tightly fit into
the cylinder bore. To remove the
cap, simply twist it back and forth
while pulling it upward; when install-
ing the cap, twist it back and forth
while pushing it downward. @

Engine oilOil level inspection
1. Place the motorcycle on a level
surface.
2. Remove the rider seat. (See page
3-13 for rider seat removal and in-
stallation procedures.)
3. Start and run the engine for seve-
ral minutes until the oil has
reached a normal temperature of
60 °C.NOTE:@ To achieve the proper engine oil tem-
perature for an accurate oil level read-
ing, the engine must have first
completely cooled down and then
warmed up again for several minutes to
normal operating temperature. @4. Place the motorcycle in an upright
position and continue idling for
10 seconds, then stop the engine.5. Remove the engine oil filler cap
and wipe the oil off the dipstick. In-
sert the dipstick back into the en-
gine oil filler hole, but do not screw
on the oil filler cap, and then pull
the dipstick out again. The oil level
should be between the maximum
and minimum level marks. If the
level is low, add sufficient oil
through the filler hole to reach the
specified level.

Carburetor adjustmentThe carburetor is a vital part of the en-
gine and requires very sophisticated
adjustment. Most adjustments should
be left to a Yamaha dealer who has the
professional knowledge and experi-
ence to do so. However, the following
may be serviced by the owner as part
of routine maintenance.
EC000094
CAUTION:@ The carburetor was set at the
Yamaha factory after many tests. If
the settings are changed, poor en-
gine performance and damage may
result. @

Idle speed adjustmentNOTE:@ 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 approximately 1,000 to
2,000 r/min. Occasionally rev the
engine to 4,000 to 4,400 r/min.
The engine is warm when it quick-
ly responds to the throttle.

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 4 ~
6 mm at the throttle grip. If the free play
is incorrect, ask a Yamaha dealer to
make this adjustment.
EAU00637
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.
EWA00011
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
(windshield, saddlebags, etc. if ap-
proved for this model). @CE-40EEWA00012
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 (windshield, saddle-
bags, 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 in-
jury. @

6 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.
CE-10E
CE-11ENOTE:@ 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. @
EAU00681
WARNING
@ l
Operating the motorcycle with
excessively worn tires decrease
riding stability and can lead to
loss of control. Have excessive-
ly worn tires replaced by a
Yamaha dealer immediately.
Brakes, tires, and related wheel
parts replacement should be
left to a Yamaha Service Techni-
cian.
l
Patching a punctured tube is
not recommended. If it is abso-
lutely necessary to do so, use
great care and replace the tube
as soon as possible with a good
quality replacement.
