A dirty air filter jeopardises the filtering of air, reducing engine power
and increasing fuel consumption. In some cases, the dust can even
reach the engine causing derious damage. For this reason, mainte-
nance of the filter should be carried out regularly.
Remove the seat to access the filter and lift the battery holder.
To remove the filter, unscrew the finger screw positioned at the centre
of the filter and carefully slide it the filter out of its case.
WARNING
- DO NOT CLEAN THE FOAM FILTER WITH FUEL OR KEROSENE, WHICH CAN
CORRODE IT. FOR CORRECT MAINTENANCE OF THE FOAM FILTER, USE THE
RELEVANT PRODUCTS ON THE MARKET FOR CLEANING AND LUBRICATION.
- NEVER START-UP THE MOTORCYCLE WITHOUT THE AIR FILTER. THE
INFILTRATION OF DUST AND DIRT CAN CAUSE DAMAGE AND INCREASE
WEAR.
Wash the filter carefully using a special liquid detergent and dry well:
squeeze the filter slightly but do not wring it. Also clean the filter case
and check that the rubber manifold that connects the carburetor to the
filter case is integral and positioned correctly.
Remount the air filter, positioning it correctly on the rest surface, taking
care that edges of the filter are not raised or not adherent with the rest
surface.
Rescrew the finger screw and tighten it adequately.

Take the crankshaft to the TDC with closed valves and activate the hand
decompressor. A free play of about 5mm. must be perceived on the end
of the lever. The end of the free play is recognised by the hardening of the
lever that starts to open the right exhaust valve. Adjust the free play if
necessary. To adjust: push the protective hood backwards, loosen the
counter-nut (1) and loosen or unscrew the adjustment screw (2). Tighten
the counter-nut and replace the protective hood.
WARNING
IF THERE IS NO FREE PLAY ON THE DECOMPRESSION LEVER, THE ENGINE
COULD BE DAMAGED.
INDICATION:
The automatic decompressor does not require adjustment.

The throttle command should always have a free play of 3-5 mm.
Moreover, when the engine is idling, the revs must not vary when steering
as far as possible to the left and to the right. To adjust the play, remove
the saddle and the tank with the shrouds. Push the protection hood
backwards (1). Loosen the counter-nut (2) and unscrew or screw the
adjustment device (3). By screwing, the free play increases. By
unscrewing, the free play decreases.
Tighten the counter-nut and control the smoothness of the the throttle
command handlebar grip. Remount the tank and saddle.
When the engine is not running, do not open and close the throttle grip
more than 1-2 times: every time it is opened it activates the accelerator
pump. This could flood the engine.
