64. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
To change the engine oil (with or
without oil filter element replace-
ment)
1. Place the vehicle on a level sur-
face.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Place an oil pan under the engine
to collect the used oil.4. Remove the engine oil filler cap,
the engine oil drain bolt and its
gasket to drain the oil from the
crankcase.
TIPSkip steps 5–8 if the oil filter element is
not being replaced.5. Remove the oil filter element cover
by removing the bolts.6. Remove the oil filter element and

seated.8. Install the oil filter element cover by
installing the bolts, then tightening
them to the specified torque.
9. Install the engine oil drain bolt and
its new gasket, and then tighten
the bolt to the specified torque.
10. Refill with the specified amount of
the recommended engine oil, and
then install and tighten the oil filler
cap.
TIPBe sure to wipe off spilled oil on any
parts after the engine and exhaust sys-
tem have cooled down.NOTICE

In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.


Make sure that no foreign mate-
rial enters the crankcase.
11. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
12. Turn the engine off, wait a few min-
utes until the oil settles, and then
check the oil level and correct it if
necessary.NOTICE
ECA11231
After changing the engine oil, make
sure to check the oil pressure as de-
scribed below.

Loosen the bleed bolt.


Start the engine and keep it
idling until oil flows out. If no oil
comes out after one minute,
turn the engine off immediately
so it will not seize. If this occurs,
have a Yamaha dealer repair the
vehicle.


After checking the oil pressure,
tighten the bleed bolt to the
specified torque.
Tightening torque:
Oil filter element cover bolt:
10 Nm (1.0 m·kgf, 7.2 ft·lbf)
Tightening torque:
Engine oil drain bolt:
20 Nm (2.0 m·kgf, 14 ft·lbf)
Recommended oil:
See page 8-1.
Oil quantity:
Without oil filter element replace-
ment:
1.30 L (1.37 US qt, 1.14 Imp.qt)
With oil filter element replacement:
1.40 L (1.48 US qt, 1.23 Imp.qt)

6 ant as soon as possible, other-
wise the cooling system will not
be protected against frost and
corrosion. If water has been
added to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possible, otherwise the
effectiveness of the coolant will
be reduced.
[ECA10472]EAU45155
To change the coolant
1. Place the vehicle on a level sur-
face and let the engine cool if nec-
essary.
2. Remove panels A and C. (See
page 6-7.)
3. Place a container under the engine
to collect the used coolant.
4. Remove the radiator cap retaining
bolt and radiator cap. WARNING!
Never attempt to remove the ra-
diator cap when the engine is
hot.
[EWA10381]
5. Remove the coolant reservoir by
removing the bolts.6. Remove the coolant reservoir cap.
7. Drain the coolant from the coolant
reservoir by turning it upside down.
8. Install the coolant reservoir by
placing it in the original position,
and then installing the bolts.

69. Remove the coolant drain bolt and
its gasket to drain the cooling sys-
tem.
10. After the coolant is completely
drained, thoroughly flush the cool-
ing system with clean tap water.
11. Install the coolant drain bolt and its
new gasket, and then tighten the
bolt to the specified torque.
12. Pour the specified amount of the
recommended coolant into the ra-
diator and reservoir.13. Install the coolant reservoir cap.
14. Install the radiator cap.
15. Start the engine, let it idle for sev-
eral minutes, and then turn it off.
16. Remove the radiator cap to check
the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radia-
tor, and then install the radiator
cap and its retaining bolt.
17. Check the coolant level in the res-
ervoir. If necessary, remove the
coolant reservoir cap, add coolant
to the maximum level mark, and
then install the cap.18. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
