STARTER KNOB

Starting a cold engine requires a larger amount
of intake air, which is supplied by the starter
knob "1".
Pushing the knob toward "a" turns ON the start-
er, resulting in a larger angle of throttle valve.
TIP
When operating the throttle grip in the closing di-
rection, the starter knob "1" moves in the direc-
tion "b" as shown and returns to its original
position.
