IDLING ADJUSTMENT
Carefully read p. 39 (MAINTENANCE).
Remember: 1 mile = 1.6 km
1 km = 0.625 miles
Adjust the idling after the first 1000 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,
then stop the engine.
◆
Position the vehicle on the stand.
Work on the right side of the
vehicle.
◆
Connect an electronic revolution counter
to the spark plug cable.
◆
Start the engine.
The minimum speed of the engine (idling)
must be about 1500
±
100 rpm.
If necessary:
◆
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 aprilia
Official Dealer.
ADJUSTING
THE ACCELERATOR CONTROL
Carefully read p. 39 (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 stand.
◆
Remove the protection element (2).
◆
Loosen the nut (3) (by turning it clock-
wise).
◆
Act on the adjuster (4), positioned at the
beginning of the accelerator control ca-
ble.
After the adjustment:
◆
Tighten the nut (3) (by turning it anti-
clockwise), thus locking the adjuster (4)
and put back the protection element (2).
