3. Do not add fuel to the fuel tank or service the
fuel system while the vehicle is near open flames,
around sparks or near someone who is smoking.
Gasoline vapor is heavier than air; it collects in low
areas and is more easily ignited than liquid gasoline.
4. Allow the engine to cool completely before
working on any fuel system component.
5. When draining the carburetor, catch the fuel in a
plastic container and then pour it into an approved
gasoline storage container.
6. Do not store gasoline in glass containers. If the
glass breaks, a serious explosion or fire may occur.
7. Immediately wipe up spilled gasoline with rags.
Store the rags in a metal container with a lid until
they can be properly disposed of, or place them out-
side in a safe place for the fuel to evaporate.
8. Do not pour water onto a gasoline fire. Water
spreads the fire and makes it more difficult to extin-
guish. Use a class B, BC or ABC fire extinguisher to
put out a gasoline fire.
9. Always turn off the engine before refueling. Do
not spill fuel onto the engine or exhaust system. Do
not overfill the fuel tank. Leave an air space at the
top of the tank to allow room for the fuel to expand
due to temperature fluctuations.
Cleaning Parts
Cleaning parts is one of the more tedious and dif-
ficult service jobs performed in the home garage.
There are many types of chemical cleaners and sol-
vents available for shop use. Most are poisonous
and extremely flammable. To prevent chemical ex-
posure, vapor buildup, fire and serious injury, ob-
serve each product warning label and note the
following:
1. Read and observe the entire product label before
using any chemical. Always know what type of
chemical is being used and whether it is poisonous
and/or flammable.
2. Do not use more than one type of cleaning sol-
vent at a time. If mixing chemicals is called for,
measure the proper amounts according to the manu-
facturer’s instructions.
3. Work in a well-ventilated area.
4. Wear chemical-resistant gloves.
5. Wear safety glasses.
6. Wear a vapor respirator if the instructions call
for it.
7. Wash hands and arms thoroughly after cleaning
parts.
8. Keep chemical products away from children and
pets.
9. Thoroughly clean all oil, grease and cleaner resi-
due from any part that must be heated.
10. Use a nylon brush when cleaning parts. Metal
brushes may cause a spark.
11. When using a parts washer, only use the solvent
recommended by the manufacturer. Make sure the
parts washer is equipped with a metal lid that will
lower in case of fire.
Warning Labels
Most manufacturers attach information and
warning labels to the vehicle. These labels contain
instructions that are important to personal safety
when operating, servicing, transporting and storing
the vehicle. Refer to the owner’s manual for the de-
scription and location of labels. Order replacement
labels from the manufacturer if they are missing or
damaged.
SERIAL NUMBERS
Serial numbers and model codes are stamped into
the motorcycle and/or printed on labels.
The VIN or vehicle identification number (
Fig-
ure 1
) appears on a label on the inside of the left
fork leg. This number is also stamped on the right
side of the steering head (
Figure 2
). Yamaha’s pri-
mary ID number is a variation of the VIN number.
The model code (
Figure 3
) appears on a label on
the side of the right main frame tube.
The engine number (
Figure 4
) is stamped on the
right side of the upper crankcase.
