EBU33702Engine oil and oil filter cartridgeCheck engine oil level before each operation.
In addition, change the oil and the oil filter car-
tridge at the intervals specified in the periodic
maintenance and lubrication chart.
To check the engine oil level
1. Park the vehicle on a level surface.
2. Check the engine oil level on a cold en- gine.TIPIf the engine was started before checking the
oil level, be sure to warm up the engine suffi-
ciently, and then wait at least 10 minutes until
the oil settles for an accurate reading. 3. Remove the passenger seat cushion (seepage 4-15 for more information).
4. Remove the rubber cover. 5. Remove the engine oil dipstick and wipe
it with a clean rag.

6. With the arrow mark pointing in the direc-tion shown, insert the dipstick completely
into the oil filler hole and then remove it
again to check the oil level.
TIPThe engine oil should be between the mini-
mum and maximum level marks. 7. If the engine oil is at or below the mini-mum level mark, add sufficient oil of the
recommended type to raise it to the cor-
rect level.
8. Install the dipstick with the arrow pointing
in the direction shown.

TIPBe sure to wipe off spilled oil on any parts af-
ter the engine and exhaust system have
cooled down. NOTICEECB00301In order to prevent clutch slippage (since
the engine oil also lubricates the clutch),
do not mix any chemical additives. Do
not use oils with a diesel specification of
“CD” or oils of a higher quality than
specified. In addition, do not use oils la-
beled “ENERGY CONSERVING II” or
higher.
 Make sure that no foreign material en-
ters the crankcase. 14. Start the engine, and then let it idle for
several minutes while checking it for oil
leakage. If oil is leaking, immediately turn
the engine off and check for the cause.

15. Turn the engine off, wait at least 10 minu-tes, and then check the oil level and cor-
rect it if necessary.
16. Install the rubber cover.
17. Install the passenger seat cushion.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. 3. If the oil is below the brim of the filler hole,
add sufficient oil of the recommended
type to raise it to the correct level.
NOTICE: Be sure no foreign material
enters the final gear case.
[ECB00422]
4. Check the gasket for damage, and re- place it if necessary.
5. Install the oil filler bolt and its gasket, and then tighten the bolt to the specified
torque.1. Final gear oil

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 differential gear 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.
EBU33660CoolantThe coolant level should be checked before
each ride. In addition, the coolant must be
changed at the intervals specified in the peri-
odic maintenance and lubrication chart.
Checking the coolant level1. Park the vehicle on a level surface.
2. Check the coolant level in the coolant reservoir when the engine is cold as the
coolant level varies with engine tempera-
ture.TIPThe coolant should be between the minimum
and maximum level marks.
Recommended oil:SAE 80 API GL-4 Hypoid gear oil
Oil quantity: 0.18 L (0.19 US qt, 0.16 Imp.qt)
Tightening torque: Differential gear oil filler bolt:23 N·m (2.3 kgf·m, 17 lb·ft)

18. When coolant begins to flow out of thebolt hole, tighten the cylinder head air
bleed bolt to the specified torque.
19. Start the engine and let it idle for ten mi- nutes.
20. Rev the engine five times.
21. Pour additional coolant into the radiator until it is full. 22. Stop the engine and allow it to cool. If the
coolant level has dropped after the en-
gine has cooled, add sufficient coolant
until it reaches the top of the radiator, and
then install the radiator cap.
23. Check the coolant level in the reservoir. If necessary, remove the coolant reservoir
cap, add coolant to the maximum level
mark, and then install the cap.
24. Start the engine, and then check for cool- ant leakage.
TIPIf any leakage is found, have a Yamaha dealer
check the cooling system. 25. Install the panels and the hood.EBU32400Axle bootsCheck the axle boots for holes or tears.
If any damage is found, have them replaced
by a Yamaha dealer.

Installation1. Clean the surface of the spark plug gas-
ket and its mating surface, and then wipe
off any grime from the spark plug
threads.
2. Install the spark plug and tighten it to the specified torque. If a torque wrench is not
available when you are installing the
spark plug, a good estimate of the cor-
rect torque is one-quarter to one-half turn
past finger tight. Have the spark plug
tightened to the specified torque as soon
as possible.
3. Install the spark plug cap.
EBU33580Cleaning the air filter elementThe air filter element should be cleaned every
20–40 hours. It should be cleaned and lubri-
cated more often if the vehicle is operated in
extremely dusty areas. Each time air filter ele-
ment maintenance is performed, check the air
inlet to the air filter case for obstructions.
Check the air filter element rubber joint to the
throttle body and manifold fittings for an air-
tight seal. Tighten all fittings securely to avoid
the possibility of unfiltered air entering the en-
gine.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.
Additionally, the fuel injection system
would be affected, resulting in poor engine
performance and possible overheating.
Spark plug gap: 0.8–0.9 mm (0.031–0.035 in)
Tightening torque: Spark plug:11 N·m (1.1 kgf·m, 8.0 lb·ft)

16. Install the storage compartment asshown.EBU33672Cleaning the air filter case/air duct
check hoseThere is a check hose at the bottom of the air
filter case and at the bottom of the air duct.
The check hoses can be accessed under the
vehicle. If dust or water collects in a check
hose, empty the hose and clean the air filter
element and air filter case.
EBU33691V-belt case drain plugThe V-belt case drain plug is located behind
the left panel. (See page 8-11 for left panel re-
moval and installation procedures.)
After operating in water deep enough to allow
water to enter the V-belt case, remove the
drain plug to drain any water from the case.
If water drains from the V-belt case after re-
moving the drai n plug, have a Yamaha dealer
inspect the vehicle, as the water may affect
other engine parts.1. Air duct check hose
2. Air filter case check hose2
