NOTICEECB00301In order to prevent cl utch 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. EBU31761CoolantCheck the coolant level in the reservoir and
replenish if necessary. (See page 8-25.)
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
the accelerator pedal for excessive free play.
If the accelerator pedal is not in correct work-
ing order, have the vehicle inspected before
starting off.

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. Changing the final gear oil
1. Park the vehicle on a level surface.
2. Place an oil pan under the final gear case
to collect the used oil.

Checking the differential gear oil level1. 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. 4. Check the gasket for damage, and re-
place it if necessary.
5. Install the differential gear oil filler bolt and its gasket, and then tighten the bolt
to the specified torque.

11. Thoroughly apply Yamaha foam air filteroil or other quality liquid foam air filter oil
(not spray type) to the sponge material.
The sponge material should be wet but
not dripping.
12. Pull the sponge material over its frame.
13. Install the air filt er element holder.
14. Install the air filter element.
15. Install the air filter case cover by fitting the
pivot holders onto the projections on the
air filter case, and th en close and lock the
cover in place with the snap holders. 16. Install the storage compartment as
shown.
EBU33673Air filter check hosesThere is a check hose at the bottom of the air
filter case and at the bottom of the air intake
duct. If dust or water collects in a check hose,
the air filter element may be soiled. Clean the
check hose, air filter element and air filter
case.

Clean the filler cap 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 does not enter the
brake fluid reservoir when refilling. Wa-
ter 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 and/or brake system leakage; therefore,
be sure to check the brake pads for wear and
the brake system for leakage. If the brake fluid
level goes down suddenly, have a Yamaha
dealer check and repair the vehicle before
any further operation.EBU32520Brake fluid replacementComplete 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 hoses every four years.

4. Once the majority of the dirt has beenhosed off, wash all surfaces with warm
water and mild, detergent-type soap. An
old toothbrush or bottle brush is handy
for hard-to-get-at places.
5. Rinse the vehicle off immediately with clean water and dry all surfaces with a
clean chamois towel or soft, absorbent
cloth.
6. Clean the seats with a vinyl upholstery cleaner to keep the covers pliable and
glossy.
7. Automotive-type wax may be applied to all 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.
EBU36120StorageLong 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 plug and pour one ta- blespoon of fresh engine oil into the cyl-
inder and then re-install the spark plug.Specified amount:1 oz of stabilizer to each gallon of fuel (or
7.5 ml of stabilizer to each liter of fuel)
