ters the oil tank. EBU35322TransmissionMake sure there is no oil leaking from the
transmission case.EBU31761CoolantCheck the coolant level in the reservoir and
replenish if necessary. (See page 8-34.)
EBU36020Final gearMake sure there is no oil leaking from the final
gear case.EBU36030Differential gearMake sure there is no oil leaking from the dif-
ferential gear case.EBU31791Accelerator pedalBefore starting the engine, confirm that the
accelerator pedal operates correctly. It
should depress smoothly and spring back to
the idle position when released. Also check

13. Install and tighten the engine oil tank fillercap and the cylinder head cap.
14. Start the engine, warm it up for several minutes, and then turn it off.
15. Remove the engine oil tank filler cap, and then add sufficient oil of the recommend-
ed type to raise it to the maximum level
mark on the dipstick.
TIPBe sure to wipe off spilled oil on any parts af-
ter the engine and exhaust system have
cooled down. 16. Install and tighten the engine oil tank fillercap.
17. Start the engine and let it idle for several minutes. During this time, check for oil
leakage. If any oil leaks are found, stop
the engine and check for the cause.
18. Stop the engine, wait at least ten minutes, and then check the oil level one last time.
19. Install the engine oil tank cover by install- ing the bolts.
20. Install the panel.
To change the engine oil and oil filter

NOTICEECB03590When checking or changing the final gear
oil, make sure that no foreign material en-
ters the final gear case. If necessary, clean
the final gear oil filler bolt and surrounding
area. Checking the final gear oil level1. 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.
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.

gear oil at the intervals specified in the gener-
al maintenance and lubrication 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.
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.
3. If the level is low, add sufficient oil of the recommended type to raise it to the
specified level.

Clean the surface of the spark plug gasket
and its mating surface, and then wipe off any
grime from the spark plug threads.TIPIf a torque wrench is not available when in-
stalling the spark plug, a good estimate of the
correct torque is 1/4–1/2 turn past finger tight.
However, the spark plug should be tightened
to the specified torque as soon as possible. NOTICEECB02900Do not use any tools to remove or install
the spark plug cap, otherwise the ignition
coil coupler may be damaged. The spark
plug cap may be difficult to remove be- cause the rubber seal on the end of the cap
fits tightly. To remove the spark plug cap,
simply twist it back and forth while pulling
it out; to install it, twist it back and forth
while pushing it in.

10. Thoroughly apply Yamalube foam air fil-ter oil (or other quality liquid foam air fil-
ter—do not use a spray-type product) to
the foam material. The foam air filter ele-
ment should be wet but not dripping.
11. Pull the foam air filter element over its frame.
12. Install the air filter.
13. Install the air filter case cover and lock it
into place by turning the air filter case
cover lock clockwise.
TIPMake sure that the match mark on the cover
lock is aligned with the close match mark on
the air filter case cover. 14. Install the panel.EBU35130Cleaning the air filter case check hosesThere is a check hose on each side of the air
filter case. If dust or water collects in a check
hose, empty the hose and clean the air filter
element and air filter case.1. Match mark

7. Automotive-type wax may be applied toall painted and chrome-plated surfaces.
Avoid combination cleaner-waxes. Many
contain abrasives which may scratch the
paint or protective finish. When finished,
start the engine and let it idle for several
minutes.EBU32741StorageLong term storage (60 days or more) of your
vehicle will require some preventive proce-
dures to guard against deterioration. Make
any necessary repairs before storing the vehi-
cle.
After thoroughly cleaning the vehicle, prepare
for storage as follows:
1. Fill the fuel tank with fresh fuel and add the specified amount of Fuel Med Rx or
another high-quality fuel stabilizer prod-
uct. Follow the instructions on the prod- uct label. Operate the vehicle for at least
5 minutes to distribute treated fuel
through the fuel system.
2. Remove the spark plugs and pour one ta- blespoon of fresh engine oil into each cyl-
inder and then re-install the spark plugs.
Remove the spark plug wires and ground
them. Operate the electric starter to turn
the engine over several times and coat
the cylinder walls with oil.
3. Lubricate all control cables.
4. Put the frame on stands or blocks to raise all wheels off the ground.
5. Tie a plastic bag over the exhaust pipe outlet to prevent moisture from entering.
Specified amount:1 oz of stabilizer to each gallon of fuel (or
7.5 ml of stabilizer to each liter of fuel)
