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
under the engine and remove the
oil filler cap.
4. Remove the drain bolt and drain
the oil.

nearby Yamaha dealer. @6. Reinstall the drain bolt and tighten
it to the specified torque.7. Apply a light coat of engine oil to
the O-ring of the new oil filter.
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
reach the specified level. Install
the oil filler cap and tighten it.

CAUTION:@ l
Do not put in any chemical addi-
tives. Engine oil also lubricates
the clutch and additives could
cause clutch slippage.

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

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.

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.)
