IDLING ADJUSTMENT
(carburettor version only)
Carefully read p. 44 (MAINTENANCE).
Adjust the idling after the first 500 km (312 mi)
and every time it is irregular.
To carry out this operation, proceed as follows:
◆
Drive for a few miles until the engine reaches
the normal running temperature, then stop
the engine.
◆
Remove the battery/tool kit compartment
cover, see p. 25 (BATTERY / TOOL KIT
COMPARTMENT).
◆
Remove the tool kit compartment.
◆
Connect an electronic revolution counter to
the spark plug cable.
WARNING
Before proceeding, make sure that the room
in which you are working is properly
ventilated.
◆
Start the engine.
◆
Make sure that the light switch is in position
“
”.
The idling speed of the engine must be about
1300 ± 100 rpm,
1500 ± 50 rpm; in this
case the engine does not make the rear
wheel rotate.
If necessary:
NOTE
The vehicle can be fitted with
different carburettor and throttle body models.
For the positioning of the adjuster, see the
figure.
◆
Act on the adjusting screw (1) positioned
on the carburettor.
NOTE
Do not act on the air adjusting screw
(2), to avoid variations of the carburation
setting.
By SCREWING IT (clockwise), you increase
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.
NOTE
If necessary, contact your
aprilia
Official Dealer.
The ideal slack of the throttle control should be
about 2-3 mm.
To adjust the slack, proceed as follows:
◆
Position the vehicle on the centre stand,
see p. 43
(POSITIONING THE VEHICLE ON
THE STAND).
◆
Remove the protection element (3).
◆
Loosen the nut (4).
◆
Act on the adjuster (5), positioned at the
beginning of the throttle control cable.
After the adjustment:
◆
Tighten the nut (4), thus locking the adjuster
(5) and refit the protection element (3).
WARNING
After the adjustment, make sure that the
rotation of the handlebar does not modify
the engine idling rpm and that the throttle
grip returns smoothly and automatically to
its original position after being released.
