Fuel Make sure that there is sufficient fuel in
the tank. Fill the fuel tank to the bottom
of the filler tube as shown.

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.
_
EAU00185
CAUTION:_ Immediately wipe off spilled fuel
with a clean, dry, soft cloth, since
fuel may deteriorate painted surfac-
es or plastic parts. _
EAU04910
ECA00104
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 premium unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand fuel. Use of unleaded fuel will ex-
tend spark plug life and reduce mainte-
nance costs.

PERIODIC MAINTENANCE AND MINOR REPAIR
6-17
615. Install the radiator cap and the
coolant reservoir cap, and then
start the engine and let it idle for
several minutes. During this peri-
od, rev the engine two or three
times between 3,000–5,000 r/min,
and then turn it off.
16. Remove the radiator cap to check
the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radia-
tor, and then install the radiator
cap.
17. Check the coolant level in the res-
ervoir. If necessary, remove the
coolant reservoir cap, add coolant
to the maximum level mark, and
then install the cap.
18. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
19. Install the cowlings and the panel.
EAU04572*
