Carefully read p. 35 (MAINTENANCE).
Remember: 1 mile = 1.6 km
1 km = 0.625 miles
Adjust the idling after the first 500 km and
every time it is irregular.
To carry out this operation, proceed as fol-
lows:
◆
Drive for a few miles until the engine
reaches the normal running temperature,
see p. 15 (Coolant temperature indicator
“
”), then stop the engine.
◆
Position the vehicle on the centre stand.
◆
Remove the right inspection cover,
seep. 46 (REMOVING THE RIGHT AND
LEFT INSPECTION COVERS).
◆
Connect an electronic revolution counter
to the spark plug cable.
◆
Start the engine.
The minimum speed of the engine (idling)
must be about 1800 ± 100 rpm; in this case
the engine does not make the rear wheel
rotate.
If necessary:
Work on the right side of the vehicle, us-
ing a small-tip, but sufficiently long screw-
driver.
◆
Act on the adjusting screw (1) positioned
on the carburettor.
By SCREWING IT (clockwise), you in-
crease the engine rpm.
By UNSCREWING IT (anticlockwise), you
decrease the engine rpm.
◆
Twist the throttle grip, accelerating and
decelerating a few times to make sure
that it functions correctly and to check if
the idling speed is constant.
Do not act on the air adjusting
screw, to avoid variations of the
carburation setting.
If necessary, contact your
DSULOLD
Official Dealer.

Carefully read p. 35 (MAINTENANCE).
The ideal slack of the accelerator control
should be about 2-3 mm.
To adjust the slack, proceed as follows:
◆
Position the vehicle on the centre stand.
Work on the left rear side of the vehicle,
and precisely on the adjusting screw posi-
tioned on the carburettor.
DO NOT withdraw the protection
element of the cold start control
cable (2).
Proceed with care. Do not bend
or force the cables or the com-
ponents of the carburettor.
◆
Remove the protection element (3).
◆
Loosen the nut (4) (by turning it clock-
wise).
◆
Act on the adjuster (5), positioned at the
beginning of the accelerator control cable.
After the adjustment:
◆
Tighten the nut (4) (by turning it anti-
clockwise), thus locking the adjuster (5)
and put back the protection element (3).
