Fuel
This motorcycle is equipped with separate lubrication. This means that the
two-stroke oil required for engine lubrication is not admixed to the fuel but
contained in a separate oil tank (see below). An oil pump is used for con-
trolled admixing of two-stroke oil into the fuel in the carburetor.
Besides, the motorcycle is equipped with a catalytic converter. Therefore, it
is absolutely necessary to fill in unleaded fuel.
Fuel:
UNLEADED REGULAR GASOLINE WITH AT LEAST 91 OCTANES (RON)
Fuel expands when its temperature rises. Therefore do not fill the tank to
the top (see fig.).
Fuel tank capacity 8.5 liter

Fuel tap
OFF In this position the fuel tap is closed. No fuel may flow to the carbu-
retor.
ON When using the motorcycle, the twist grip must be set to the ON
position. Now fuel may flow to carburetor. In this position the tank
empties down to the fuel reserve of approx. 3 liters.
RES The reserve tank, approximately 3 liters, cannot be tapped until the
twist grip is turned to the RES position. Fill the tank as soon as possi-
ble and remember to turn the twist grip back to the ON position so
that you will have backup fuel next time, too.
