WARNING
POTENTIAL HAZARD
Improper care when refueling.
WHAT CAN HAPPEN
Fuel can spill, which can cause a fire and se-
vere injury.
Fuel expands when it heats up. If the fuel
tank is overfilled, fuel could spill out due to
heat from the engine or the sun.
HOW TO AVOID THE HAZARD
Do not overfill the fuel tank. Be careful not to
spill fuel, especially on the engine or exhaust
pipe. Wipe up any spilled fuel immediately.
Be sure the fuel tank cap is closed securely.
Do not refuel right after the engine has been
running and is still very hot.
NOTICE
Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the valves and piston
Your Yamaha engine has been designed to use
regular unleaded gasoline with a pump octane
number [(R+M)/2] of 86 or higher, or a research oc-
tane number of 91 or higher. If knocking or pinging
occurs, use a different brand of gasoline or premi-
um unleaded fuel. Unleaded fuel will give you long-
er spark plug life and reduced maintenance cost.
Gasohol
There are two types of gasohol: gasohol contain-
ing ethanol and that containing methanol. Gasohol
containing ethanol can be used if the ethanol con-
tent does not exceed 10%. Gasohol containing
methanol is not recommended by Yamaha be-
cause it can cause damage to the fuel system or
ATV performance problems.
rings, as well as to the exhaust system.
