Idle Speed Adjustment
150cc=1/-
50cc=1/-
Engine idle speed should be adjusted to 1400 rpm for the 150cc and 1900 rpm
for the 50cc. However, when the scooter is new, it may need to be adjusted a
little higher until the engine breaks in to prevent dying at stop lights, etc. If you
don t have a tachometer you can adjust by ear. The idle should be adjusted just
high enough so that when set on the center stand with rear wheel elevated, the
wheel turns very slowly. Adjusting the idle is a very simple procedure.
The easiest way to get to the
idle screw is to remove the well under
your seat. Locate the screws and/or
nuts securing the well and remove
them. On most models, the gas cap
must also be removed.
Turn the screw clockwise to
increase the idle, counterclockwise to
decrease the idle.
