Fuel expands when its temperature rises. Therefore do not fill the tank to the top
(see fig.).

Fuel tap

OFF In this position the fuel tap is closed. No fuel may flow to the carburetor.
ON When using the motorcycle, the rotating handle must be set to the ON posi-
tion. Now fuel may flow to carburetor. In this position the tank empties
down to the fuel reserve of approx. 1,5 liters.
RES The reserve tank, approximately 1,5 liters, cannot be tapped until the rota-
ting handle is turned to the RES position. Fill the tank as soon as possible
and remember to turn the rotating handle back to the ON position so that
you will have backup fuel next time, too.

Choke (SX, SC)
In these models the choke operating element is located on the engine. Pull the
1
knob
and turn it (approx. 90°) to open a bore in the carburetor through which
the engine can take in additional fuel. The result is a „fat" fuel-air mixture of the
type needed for cold starts.
To close the bore in the carburetor, turn the knob again (approx. 90°); the knob
moves back into its initial position. In this position, the play of the choke cable
must be approximately 2 mm (0.1 in).
