 WARNING
If you overfill the fuel tank, fuel may
overflow when it expands due to engine
heat or heating by the sun. Fuel that
overflows can catch fire.
Stop adding fuel when the fuel level
reaches the bottom of the filler neck.
 WARNING
Failure to follow safety precautions
when refueling could result in a fire or
cause you to breathe toxic fumes.
Refuel in a well ventilated area. Make
sure the engine is off and avoid spilling
fuel on a hot engine. Do not smoke, and
make sure there are no open flames or
sparks in the area. Avoid breathing gas-
oline vapors. Keep children and pets
away when you refuel the motorcycle.
