To install the panelPlace the panel in the original position, and
then install the quick fastener screws.EBU35433Engine oil and oil filterCheck the engine oil level before each opera-
tion. In addition, change the oil and replace
the filter at the intervals specified in the gen-
eral maintenance and lubrication chart.
To check the engine oil level1. Park the vehicle on a level surface.
2. Remove panel C (page 8-10). 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. 4. Remove the engine oil tank filler cap and
wipe the dipstick with a clean rag.
5. Insert the dipstick back into the oil tank
(without screwing it in), and then remove
it again to check the oil level.TIPThe engine oil level should be between the tip
of the dipstick and the maximum level mark.

In order to prevent clutch slippage, do
not mix any chemical additives. TIPBe sure to wipe up any spilled oil. 7. Start the engine and drive the vehicle for
a few minutes to circulate the transmis-
sion oil.
8. Park the vehicle on a level surface, stop
the engine, and then check the transmis-
sion case for oil leakage.TIPIf oil is leaking confirm that the transmission
oil filler cap is properly installed and then have
a Yamaha dealer check the transmission. 9. Check the transmission oil level and cor-rect if necessary.
10. Install the panel.
EBU36050Final gear oilCheck the oil level and change the final gear
oil at the intervals specified in the general
maintenance and lubrication chart.
Checking the final gear oil level 1. Park the vehicle on a level surface.
2. Remove the final gear oil filler bolt and its gasket, and then check the oil level in the
final gear case. The oil level should be at
the brim of the filler hole.

4. Install the drain bolt and its new gasket,and then tighten the bolt to the specified
torque.
5. Refill with the recommended final gear oil up to the brim of the filler hole. NOTICE:
Be sure no foreign material enters the
final gear case.
[ECB00422]
TIP GL-4 is a quality and additive rating; GL-5
rated hypoid gear oils may also be used.
If desired, an SAE 80W -90 hypoid gear oil
may be used instead.
6. Check the oil filler bolt gasket for dam- age, and replace it if necessary.
7. Install the oil filler bolt and its gasket, and then tighten the bolt to the specified
torque.
8. Check for oil leakage. If oil leakage is found, check for the cause.EBU36060Differential gear oilCheck the oil level and change the differential
gear oil at the intervals specified in the gener-
al maintenance and lubrication chart.
Checking the differential gear oil level
1. Park the vehicle on a level surface.
Tightening torque: Final gear oil drain bolt:23 Nm (2.3 m·kgf, 17 ft·lbf)
Recommended oil: SAE 80 API GL-4 Hypoid gear oil
Oil quantity: 0.47 L (0.50 US qt, 0.41 Imp.qt)
Tightening torque:Final gear oil filler bolt:23 Nm (2.3 m·kgf, 17 ft·lbf)

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

EBU35423Air 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 dusy 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 case 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
EWB03910Improper maintenance can result in loss of
braking ability or clutch operation. Ob-
serve these precautions:
Insufficient brake or clutch fluid may al-
low air to enter the brake or clutch sys-
tem, reducing braking or 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 clutch fluid reservoir
when refilling. Water will significantly
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 clutch fluid
level may indicate clutch system leakage;
therefore, be sure to check the clutch system
for leakage. If the brake or clutch fluid level
goes down suddenly, have a Yamaha dealer
check and repair the vehicle before any fur-
ther operation.
