CAUTION:_ Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the valves and piston
rings, as well as to the exhaust system. _
WARNING
Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is over-
filled, fuel could spill out due to heat from
the engine or the sun.
Be careful not to spill fuel, especially on
the engine or exhaust pipe which can
cause a fire and severe injury. Wipe up any
spilled fuel immediately.
Be sure the fuel tank cap is closed secure-
ly.

Troubleshooting
Although Yamaha vehicles receive a rigid inspec-
tion before shipment from the factory, trouble may
occur during operation. Any problem in the fuel,
compression, or ignition systems can cause poor
starting and loss of power. The troubleshooting
chart describes a quick, easy procedure for mak-
ing checks. If your vehicle requires any repair, take
it to a Yamaha dealer.
The skilled technicians at a Yamaha dealership
have the tools, experience, and know-how to prop-
erly service your vehicle. Use only genuine
Yamaha parts on your vehicle. Imitation parts may
look like Yamaha parts, but they are often inferior.
Consequently, they have a shorter service life and
can lead to expensive repair bills.
WARNING
Do not smoke when checking the fuel system.
Fuel can ignite or explode, causing severe in-
jury or property damage. Make sure there are
no open flames or sparks in the area, including
pilot lights from water heaters or furnaces.

B. STORAGE
Long term storage (60 days or more) of your vehi-
cle will require some preventive procedures to
guard against deterioration. After thoroughly
cleaning the vehicle, prepare for storage as fol-
lows:
1. Fill the fuel tank with fresh fuel and add fuel
stabilizer (if available). Operate the vehicle
for at least 5 minutes to distribute treated fuel
through the fuel system.
2. Drain the fuel from the carburetor float cham-
ber into a clean container by loosening the
drain bolt; this will help prevent fuel deposits
from building up. Pour the drained fuel into
the fuel tank.NOTE:_ Use of fuel stabilizer eliminates the need to drain
the fuel system. Consult a Yamaha dealer if the
fuel system is to be drained instead. _
