WARNING
_
Do not overfill the fuel tank, oth-
erwise it may overflow when the
fuel warms up and expands.
Avoid spilling fuel on the hot
engine.
_
EAU00186
CAUTION:_
Immediately wipe off spilled fuel
with a clean, dry, soft cloth,
since fuel may deteriorate paint-
ed surfaces or plastic parts.
For Germany only: Whenever
replacement is necessary, use a
fuel tank cap of the same spe-
cial design as the original.

CAUTION:_ Use only unleaded gasoline. The
use of leaded gasoline will cause se-
vere damage to internal engine
parts, such as the valves and piston
rings, as well as to the exhaust sys-
tem. _Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand or premium unleaded fuel. Use
of unleaded fuel will extend spark plug
life and reduce maintenance costs.

ervoir. If necessary, remove the
coolant reservoir cap, add coolant
to the maximum level mark, and
then install the cap.
20. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
