erwise it may overflow when the
fuel warms up and expands.


Avoid spilling fuel on the hot
engine.

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
95 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.

with the engine speed by a computer-
controlled servomotor.
EC000027
CAUTION:_

The EXUP system has been set
and extensively tested at the
