2) 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.

Correct idling-speed adjustment is only
possible if the engine is fully warmed-up.

a Yamaha dealer or other qualified
mechanic.
