GASOLINE AND EXHAUST GAS
1. GASOLINE IS HIGHLY FLAMMABLE:
a. Always turn off the engine when refueling.
b. Take care not to spill any gasoline on the engine or exhaust system when refueling.
c. Never refuel while smoking or in the vicinity of an open flame.
2. Never start the engine or let it run for any length of time in a closed area. The exhaust fumes are poisonous and may cause
loss of consciousness and death within a short time. Always operate your motorcycle in an area that has adequate ventilation.
3. Always turn off the engine before leaving the machine unattended and remove the ignition key. When parking the machine,
note the following:
a. The engine and exhaust system may be hot. Park the machine in a place where pedestrians or children are not likely to
touch these hot areas.
b. Do not park the machine on a slope or soft ground; the machine may fall over.
c. Do not park the machine near a flammable source, e. g. a kerosene heater, or near an open flame. The machine could
catch fire.
4. When transporting the machine in another vehicle, be sure it is kept upright and that the fuel cock is turned to “ON” or “RES”
(for vacuum type) / “OFF” (for manual type).
If it should lean over, gasoline may leak out of the carburetor or fuel tank.
5. If you should swallow any gasoline, inhale a lot of gasoline vapor, or allow gasoline to get in your eyes, see your doctor
immediately. If any gasoline spills on your skin or clothing, immediately wash it off with soap and water and change your
clothes.

CAUTION:
Always wipe off spilled fuel immediately with a dry and
clean soft cloth. Fuel may deteriorate painted surfaces
or plastic parts.
Fuel
-./ - .0
Make sure there is sufficient fuel in the tank.
Do not overfill the fuel tank. Avoid spilling fuel on the
hot engine. Do not fill the fuel tank above the bottom of
the filler tube as shown in the illustration or it may
overflow when the fuel heats up later and expands.
Recommended fuel:
UNLEADED FUEL
Fuel tank capacity:
Total:
10.6 l ( 2.33 Imp gal, 2.80 US gal)
Reserve:
1.0 l ( 0.220 Imp gal, 0.264 Us gal)
Your Yamaha engine has been designed to use regular
unleaded gasoline with a pump octane number ([R+m]/2)
of 86 or higher, or research octane number of 91 or higher.
If knocking or pinging occurs, use a different brand of
gasoline or premium unleaded fuel. Unleaded fuel will give
you longer spark plug life and reduced maintenance cost.
If unleaded gasoline is not available, then leaded regular
gasoline can be used.
Gasohol
There are two types of gasohol; gasohol containing ethanol
and that containing methanol. Gasohol containing ethanol
can be used if ethanol content does not exceed 10%.
Gasohol containing methanol is not recommended by
Yamaha because it can cause fuel system damage or
vehicle performance problems.
