4-PRE-OPERATION CHECKSOwners are personally responsible for their vehicle’s condition. Your motorcycle’s vital functions can start to deteriorate
quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any damage, fluid leak or
loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition to a thorough visual in-
spection, you check the following points before each ride.
EAU00340

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. @
EC000067
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.
EAU01594
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.
Oil quantity:
Total amount:
3.5 L
Periodic oil change:
3.0 L
With oil filter replacement:

@ Do not remove the radiator cap
when the engine is hot. @
EC000080
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. @
EAU01332
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.)

Support the fuel tank carefully
during this procedure.

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

Engine overheating
EW000070
WARNING
@ Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be blown
out under pressure, which could cause serious injury. Open the radiator cap as follows. Wait until the engine has
cooled. Remove the radiator cap stopper by removing the screw. Place a thick rag like a towel over the radiator cap
and slowly rotate the cap counterclockwise to the detent. This procedure allows any residual pressure to escape.
When the hissing sound has stopped, press down on the cap while turning counterclockwise and remove it. @NOTE:@ If it is difficult to get the recommended coolant, tap water can be temporarily used, provided that it is changed to the recom-
mended coolant as soon as possible. @
Wait until the
engine has cooled.
Check the coolant level in the
reservoir tank and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See NOTE.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and repair the cooling system.
