Mount the filter together with the filter
bracket and fix them with the rubber
washer and the screw.
! WARNING !
Do not clean air-filter with fuel or
petroleum since these will damage
the foam.
Never use fuel or diluent to clean
air filter box, to avoid damage
sealing silicon between box and
cover.
Keep air filter clean and lubricated
(wet in oil) to assure a more
effective protection of engine
cylinder.
Never start your motorcycle without
air filter, otherwise dust or dirt may
penetrate in the engine and cause
damage or severe wear.
FUEL FILTER
Fuel filter is placed between right beam
and carburettor, below driver’s seat.
It should be replaced whenever there
is dirt on it, because dirt can reduce or
block fuel flow producing loss of power
or irregular engine functioning.
THROTTLE CABLE
Adjusting throttle cable
The throttle grip should always provide
for a backlash of 2-6mm, measured in
the adjusting screw outside the throttle
grip. Besides, with the engine running,
the idling speed must not change if you
turn the handlebar all the way to the left
or right.
To adjust throttle cable, draw back dust
protection, loosen the counter nut (1)
and turn the adjusting screw
accordingly (2). Tighten the counter nut
and check whether the throttle grip can
be actuated smoothly.
