-
Note the position and turn the idle adjusting screw slowly counterclockwise until
the idle

- Adjust to the point
between these two positions with the highest idle speed.
• Info
I If there is a large engine speed rise, reduce the idle speed to a normal level
and repeat the above steps.
The extreme sport motorcyclist will set the mixture about 1M of a turn back
from this ideal value (leaner, in a clockwise direction) since the engine
becomes hotter in sporting use.
If the procedure described here does not lead to satisfactory results, the
cause may be a wrongly dimensioned idling jet.
If
you can turn the idle adjusting screw to the end without any change of
engine speed, you have to fit a smaller idling jet.
The idle adjusting screw must not be opened more than two turns. If more
than two turns are necessary (rich mixture), use a larger idling jet.
After changing the idling jet, repeat the adjusting steps from the beginning.
