Engine oilOil level inspection
1. Place the motorcycle on a level
place and hold it in an upright posi-
tion. Warm up the engine for seve-
ral minutes.NOTE:@ Be sure the motorcycle is positioned
straight up when checking the oil level.
A slight tilt toward the side can result in
false readings. @
2. With the engine stopped, check
the oil level through the level win-
dow located at the lower part of
the right side crankcase cover.NOTE:@ Wait a few minutes until the oil level
settles before checking. @3. The oil level should be between
maximum and minimum marks. If
the level is low, fill the engine with
sufficient oil to reach the specified
level.Engine oil and oil filter cartridge re-
placement
1. Remove cowling A. (See page 6-5
for removal and installation proce-
dures.)
2. Warm up the engine for several
minutes.
3. Stop the engine. Place an oil pan

NOTE:@ Make sure the O-ring is seated proper-
ly. @
8. Install the oil filter and tighten it to
the specified torque with an oil fil-
ter wrench.NOTE:When installing the oil filter, tighten it to
the proper torque by using a torque
wrench.9. Fill the engine with sufficient oil to

CAUTION:@ l
Do not put in any chemical addi-
tives. Engine oil also lubricates
the clutch and additives could
cause clutch slippage.
l
Be sure no foreign material en-
ters the crankcase.

10. Start the engine and warm it up for
several minutes. While warming
up, check for oil leakage. If oil
leakage is found, stop the engine
immediately and check for the
cause.NOTE:@ After the engine is started, the oil level
indicator light should go off if the oil is at
the specified level. @

CAUTION:@ If the indicator light flickers or re-
mains on, immediately stop the en-
gine and consult with a Yamaha
dealer. @11. Install the cowling stay and cowl-
ing.

CoolantCheck the coolant level in the reservoir
tank when the engine is cold. The cool-
ant level will vary with engine tempera-
ture. The coolant level is satisfactory if
it is between the minimum and maxi-
mum marks on the tank. If the coolant
level is at or below the minimum mark,
fill with tap water (soft water) to bring
the level up to the maximum mark.
Have a Yamaha dealer change the
coolant every two years. Recommended oil:
See page 8-1.

CAUTION:@ Hard water or salt water is harmful
to the engine. You may use distilled
water if you can’t get soft water. @NOTE:@ The radiator fan operation is complete-
ly automatic. It is switched on or off ac-
cording to the coolant temperature in
the radiator. @

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 seats.
2. Remove cowling B from each side.
(See page 6-5.)
3. Remove the bolts holding the fuel
tank.
4. Lift the fuel tank upward and posi-
tion it away from the air filter case.
(Do not remove the fuel hoses.)

Do not tilt the fuel tank too
much or pull it too hard because
the fuel hose connections may
become loose causing fuel
leakage.

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.

@ 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. @
