Checking the basic position of the shift lever

Info
When driving, the shift lever must not touch the rider's boot when in the basic position.
When the shift lever keeps touching the boot, the transmission will be subject to an excessive load.

Adjusting the basic position of the shift lever

Info
If there is a big engine speed rise, reduce the idle speed to a
normal level and repeat the above steps.
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 air adjusting screw to the end with-
out any change of engine speed, mount a smaller idling jet.
After changing the idling jet, start from the beginning with
the adjusting steps.
Following extreme air temperature or altitude changes,
adjust the idle speed again.
Sit on the vehicle in the riding position and determine distance
between the upper edge of your boot and the shift lever.
