Maintenance

Checking the ignition timing

- Adjust the control cables:
Mix cable: see procedure indicated in "Mixer tim-
ing".
Throttle cable: adjust the set screw on the carbu-
rettor in such a way that the sheath has no back-
lash.
Splitter control cable: adjust set screw on the throt-
tle control to the handlebar in such a way that there
is no backlash on the throttle control.
Adjust all transmissions in such a way that their
sheathings show no sign of backlash.
Mixer Timing
- Using the transmission set screw on the crank-
case, with throttle control untwisted, adjust the
reference mark on the rotating plate so that it is
lined up with the reference mark on the mixer
body, as shown in the figure.
While doing this, the engine must be fuelled with a
2 % oil mixture (0.5 litre minimum if the reservoir
is empty).
CAUTION
IN CASE OF DISMANTLING OR RUNNING OUT
OF OIL IN THE RESERVOIR BLEED THE MIXER
AS FOLLOWS: REFILL THE OIL RESERVOIR
WHEN THE MIXER IS FITTED TO THE VEHICLE
AND THE ENGINE IS OFF, UNDO THE MIXER
PIPE FROM THE CARBURETTOR AND LOOS-
EN THE BLEED SCREWS (SEE THE ARROW IN
THE FIGURE) UNTIL THE OIL BEGINS TO
FLOW OUT. TIGHTEN THE SCREWS, START
UP THE ENGINE AND WAIT FOR OIL TO FLOW
OUT OF THE TUBE. RECONNECT THE DELIV-
ERY PIPE TO THE CARBURETTOR AND FIX IT
IN PLACE WITH THE RELEVANT METAL CLIP.
