Engine overheating
Wait for the engine to cool before removing the radiator cap. WARNING! If the engine is not
cool when removing the radiator cap, hot fluid and steam could blow out under pressure
and burn you.
[EWB03460]
Place a thick rag over the cap and remove the cap slowly to allow any re-
maining pressure to escape.
TIP Tap water can be used in an emergency. Ch ange to the recommended coolant as soon as
possible.
 The engine will tend to overheat if the radiator is caked with mud, or if air was not properly bled
from the cooling system. Wait until the
engine has cooled.
Check the coolant le vel in the
coolant reservoir and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See TIP.)
Restart the engine. If the engine o verheats again, ask a
Yamaha dealer to inspect and/or repair the cooling system.

CLEANING AND STORAGE
EBU35920CleaningFrequent, thorough cleaning of your vehicle
will not only enhance its appearance but will
improve its general performance and extend
the useful life of many components.1. Before cleaning the vehicle: a. Block off the end of the exhaust pipeto prevent water entry. A plastic bag
and strong rubber band may be used.
b. Make sure the spark plugs and all filler caps are properly installed.
2. If the engine case is excessively greasy, apply degreaser with a paint brush. Do
not apply degreaser to the wheel axles.
3. Rinse the dirt and degreaser off with a garden hose. Use only enough pressure
to do the job. WARNING! Test the
brakes after washing. Apply the
brakes several times at slow speeds to
let friction dry the brakes. Wet brakes may have reduced stopping ability, in-
creasing the chance of an accident.
[EWB03471]

NOTICE: Excessive water pres-
sure may cause water seepage and
deterioration of wheel bearings,
brakes, transmission seals and electri-
cal devices. Many expensive repair
bills have resulted from improper high-
pressure detergent applications such
as those available in coin-operated car
washers.
[ECB00712]
4. Once the majority of the dirt has been hosed 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 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)
