Adjust the throttle stop-screw to set
the idling speed to specification (see
“SPECIFICATIONS”) by turning the
stop-screw clockwise to increase the
idling speed, and turning it counter-
clockwise to decrease the idling
speed.
NOTE:
Correct idling-speed adjustment is only
possible if the engine is fully warmed-up.
If not warmed up fully, the speed setting
will tend to be too high.
If you have difficulty obtaining the speci-
fied idle, consult a Yamaha dealer or
other qualified mechanic.
