Fuel Cock

The fuel cock lever has three positions:
"ON" fuel supplied to carburettor when the
engine starts.
"OFF" select when the motorcycle is not in
use for a long period or being
serviced.
"RES" reserve fuel tank (holds approx 2
litres of fuel) is selected. Turn to
RES when you run out of fuel in ON
position whilst riding. Refuel as soon
as possible and turn back to ON to
prevent complete fuel starvation.
