tion. In addition, change the oil and the oil fil-
ter cartridge at the intervals specified in the
periodic maintenance chart.
NOTICEECB03020 Do not use oils with a diesel specifica-
tion of “CD” or oils of a higher quality
than specified. In addition, do not use
oils labeled “ENERGY CONSERVING II”
or higher.
 Make sure that no foreign material en-
ters the oil tank. To check the engine oil level
1. Park the vehicle on a level surface.
2. Remove panel D. (See page 9-11.)
3. Start the engine and warm it up to a nor- mal operating temperature (the engine oil
temperature should reach 60 °C [140 °F]),
then let the engine idle for a minimum of
ten seconds before turning the engine off.TIPIf the engine is cold, take the vehicle for a
short drive or let it idle for approximately ten
minutes before checking the engine oil level.

use. Yamalube oils take full advantage of the
base oil’s qualities and blend in the ideal ba-
lance of additives to make sure the final oil
clears our performance standards. Thus,
Yamalube mineral, semisynthetic and syn-
thetic oils have their own distinct characters
and value. Yamaha’s experience gained over
many years of research and development into
oil since the 1960’s helps make Yamalube the
best choice for your Yamaha engine.EBU35108Transmission oilCheck the oil level and change the transmis-
sion oil at the intervals specified in the period-
ic maintenance chart.
NOTICEECB02910When checking or changing the transmis-
sion oil, make sure that no foreign material
enters the transmission. If necessary,
clean the filler cap and surrounding area. To check the transmission oil level 1. Park the vehicle on a level surface.
2. Remove panel B. (See page 9-11.)
3. Remove the transmission oil filler cap, wipe the dipstick clean, insert it back into
the transmission case (without screwing
it in), and then remove it again.Recommended oil:YA M A L U B ESAE 5W-30, 10W-30, 10W-40, 15W-40,
20W-40 or 20W-50

TIPOil will flow out immediately when the drain
bolt is loosened. Take care not to lose the
bolt. 4. After draining the oil, install the transmis-sion oil drain bolt with a new gasket.
5. Tighten the drain bolt to the specified torque. 6. Check the O-ring for damage, and re-
place it if necessary.
7. Refill the transmission with the specified amount of the recommended oil.
8. Install the transmission oil filler cap.
9. Start the engine and let it idle while checking for oil leakage.
10. Stop the engine and check the oil level one last time.

7. Install the oil filler bolt and its gasket, andthen tighten the bolt to the specified
torque.
8. Check for oil leakage. If oil leakage is found, check for the cause.EBU36064Differential gear oilCheck the oil level and change the differential
gear oil at the intervals specified in the period-
ic maintenance chart.NOTICEECB03600When checking or changing the differen-
tial gear oil, make sure that no foreign ma-
terial enters the differential gear case. If
necessary, clean the differential gear oil
filler bolt and surrounding area.
TIPIf the recommended gear oil is not available,
SAE 80W-90 API GL-4 or GL-5 hypoid gear
oil may be used instead. Checking the differential gear oil level 1. Park the vehicle on a level surface.
2. Remove the differential gear oil filler bolt and its gasket, and then check the oil lev-
el. It should be up to the brim of the filler
hole.
Tightening torque:Final gear oil filler bolt:22 N·m (2.2 kgf·m, 16 lb·ft)
Recommended oil:SAE 80 API GL-4 Hypoid gear oil
Oil quantity: 0.18 L (0.19 US qt, 0.16 Imp.qt)

it with coolant as soon as possible,
otherwise the cooling system will not
be protected against frost and corro-
sion. If water has been added to the
coolant, have a Yamaha dealer check
the antifreeze content of the coolant
as soon as possible, otherwise the ef-
fectiveness of the coolant will be re-
duced.
[ECB01012]
6. Install the panel when finished servicing
the vehicle. To change the coolant
The coolant must be changed at the intervals
specified in the periodic maintenance chart.
Have a Yamaha dealer change the coolant.
WARNING! Never attempt to remove the
radiator cap when the engine is hot.

EBU35121Checking the spark plugsThe spark plug is an important engine com-
ponent which should be periodically
checked, preferably by a Yamaha dealer.
Since heat and deposits will cause any spark
plug to slowly erode, the spark plugs should
be removed and checked in accordance with
the periodic maintenance chart for the emis-
sion control system. In addition, the condition
of the spark plugs can reveal the condition of
the engine. The porcelain insulator around the center
electrode of each spark plug should be a me-
dium-to-light tan color (the ideal color when
the vehicle is ridden normally), and all spark
plugs installed in the engine should have a
similar color. If any spark plug shows a dis-
tinctly different color, the engine could be op-
erating improperly. Do not attempt to
diagnose such problems yourself. Instead,
have a Yamaha dealer check the vehicle.
If a spark plug shows signs of electrode ero-
sion and excessive carbon or other deposits,
it should be replaced.
Before installing a spark plug, the spark plug
gap should be measured with a wire thick-
ness gauge and, if necessary, adjusted to
specification.1. Rear axle boot

EBU38320Air filter maintenanceThis model is equipped with two air filter ele-
ments, a primary foam-type air filter and a
secondary paper-type air filter.
The primary air filter is easily accessed and
should be cleaned and oiled every 300–600
km (200–400 mi).
The secondary air filter is more difficult to ac-
cess, cannot be cleaned, and should be re-
placed by a Yamaha dealer every 2000–5000
km (1200–3000 mi).
TIPService the air filters more frequently when
operating in wet or dusty environments. Whenever air filter maintenance is performed:
check the air inlet for obstructions and the
air filter case for dirt and foreign matter.
 check the air filter case check hoses for dirt
or water and clean as necessary.
 check the air filter cas e joints and the rub-
ber joints to and from the throttle body for
proper fit and sealing.
 tighten all fittings securely to avoid the pos-
sibility of unfiltered air entering the engine.NOTICEECB02270Never operate the engine with the air filter
element removed. Doing so would allow
unfiltered air to enter, causing rapid en-
gine wear and possible engine damage.

WARNING
EWB04160Improper maintenance can result in loss of
braking ability or YCC-S clutch operation.
Observe these precautions:
Insufficient brake or YCC-S clutch fluid
may allow air to enter the brake or
YCC-S clutch system, reducing braking
or YCC-S clutch performance.
 Clean the filler caps before removing.
Use only DOT 4 brake fluid from a sealed
container.
 Use only the specified brake fluid; other-
wise, the rubber seals may deteriorate,
causing leakage.
 Refill with the same type of brake fluid.
Adding a brake fluid other than DOT 4
may result in a harmful chemical reac-
tion. 
Be careful that water or dust does not
enter the brake or YCC-S clutch fluid
reservoir when refilling. Water will signif-
icantly lower the boiling point of the fluid
and may result in vapor lock.
NOTICEECB01161Brake fluid may damage painted surfaces
or plastic parts. Always clean up spilled
fluid immediately. As the brake pads wear, it is normal for the
brake fluid level to gradually go down. A low
brake fluid level may indicate worn brake
pads or brake system leakage; therefore, be
sure to check the brake pads for wear and the
brake system for leakage. A low YCC-S
clutch fluid level may indicate YCC-S clutch
system leakage; therefore, be sure to check
the YCC-S clutch system for leakage. If the
brake or YCC-S clutch fluid level goes down

suddenly, have a Yamaha dealer check and
repair the vehicle before any further opera-
tion.EBU36550Brake and YCC-S clutch fluid replace-
mentComplete fluid replacement should be done
only by trained Yamaha service personnel.
Have a Yamaha dealer replace the following
components during periodic maintenance or
when they are damaged or leaking.
Replace the oil seals every two years.
 Replace the brake and YCC-S clutch hoses
every four years.EBU36540YCC-S clutchThis model is equipped with a hydraulic
clutch, therefore, it is necessary to check the
YCC-S clutch fluid level and check the hy-
draulic system for leak age before each drive.
If the YCC-S clutch plates wear out, shifting
becomes rough or clutch slippage will occur, causing poor acceleration. If any of the above
occurs, have a Yamaha dealer check the
YCC-S clutch.
EBU32531Checking the brake pedalHave a Yamaha dealer check the brakes at
the intervals specified in the periodic mainte-
nance chart. There should be no free play in
the brake pedal. The brakes should operate
smoothly and there should be no brake drag.
If the brakes feel soft or spongy, this could in-
dicate air in the brake system. Have a
Yamaha dealer check the brake system if necessary.
