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. 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.

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)

8. Disconnect the coolant reservoir hose,and then drain the coolant from the cool-
ant reservoir.
9. After draining the coolant, thoroughly flush the cooling system with clean tap
water.
10. Install the coolant drain bolt and its new gasket and then tighten the bolt to the
specified torque. 11. Connect the coolant reservoir hose.
12. Pour the recommended coolant into the
radiator until it is full.
13. Pour the recommended coolant into the
reservoir to the maximum level mark, and
then install the reservoir cap.
NOTICEECB02190Mix antifreeze with distilled water only.
However, if distilled water is not available,
soft water may be used for refilling. Do not
use hard water or salt water since they are
harmful to the engine.

14. Remove the right panel and right rearpanel. (See page 8-11 for right panel and
right rear panel removal and installation
procedures.)
15. Loosen the water pump air bleed bolt, without removing it, to allow all of the air
to escape from the air bleed bolt hole. 16. When coolant begins to flow out of the
bolt hole, tighten the water pump air
bleed bolt to the specified torque.
17. Loosen the cylinder head air bleed bolt, without removing it, to allow all of the air
to escape from the air bleed bolt hole.Antifreeze/water mixture ratio:1:1
Recommended antifreeze: High-quality ethylene glycol antifreeze con-
taining corrosion inhibitors for aluminum
engines
Coolant quantity: Radiator (including all routes):2.85 L (3.01 US qt, 2.51 Imp.qt)

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)
