Idle adjustment (03_17, 03_18)
The idle speed is adjusted by means of the idle speed adjuster screw «
A
» located on
the carburettor.
To do this, proceed as shown in the diagram. Turn the register for adjusting the clear-
ance of the throttle control transmission «
B
», then replace the rubber protection cap.
Adjust the idle speed with the rear wheel off the ground (vehicle on stand) and with a
warm engine. Turn the knob-type head screw in or out until the engine idles smoothly
(around 1700÷1900 rpm.),
i.e. without the rear wheel being moved by the en-
gine
.
If adjustment still proves difficult, contact an
Authorised Piaggio Service Centre
to
have the level of
CO when idling fixed
(carbon monoxide emissions).
CAUTION
WHEN ADJUSTING IDLE SPEED, BE CAREFUL NOT TO TOUCH HOT PARTS OF
THE ENGINE TO AVOID BURNS.

Front and rear disc brake (03_19, 03_20)
The brake disc and pad wear is automatically compensated, therefore it has no effect
on the functioning of the front and rear brakes. For this reason it is not necessary to
adjust the brakes. An excessively elastic brake lever stroke may indicate the presence
of air in the braking circuit or an irregular brake operation. In this case, particularly
considering the importance of the brakes in terms of safety, it is strongly recommended
that you take the vehicle to an
Authorised Service Centre
as soon as possible for
the appropriate checks.
