time to time in petrol. Clean from to time the hole B
of exhaust silencer (fig 9) from the carbon. When
bigger decrease of output check whether the

The oil in the gear box is to be changed after the
ride only, when the oil and the engine are warm.
Unscrew the discharge screw from the engine

bottom part (2, fig.11). After discharging the oil it is
suitable to wash the gear box by the rinse oil. Fill
the new gear oil through the filling hole 1 up to
control orifice 3. From time to time check the oil
level in the gear box and refill if required.
