For this purpose, remove drivers seat,
by unscrewing to screw (1) in the back
of the seat and pull it in to rear
direction. Then remove air filter’s cover
by unscrewing fixation screw (2).
Thoroughly wash the air-filter in special
cleaning fluid and allow it to dry well. Oil
the dry air filter with high-grade filter oil
and clean the air filter box.
For extra security, apply grease on the
back side of the filter, which mates with
air filter box.
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 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.
IDLING
Adjust idling
Idling adjustment of the carburettor
strongly affects the engine starting
behaviour, that is, an engine whose
idling speed is adjusted correctly will be
easier to start.
The idle sped is controlled by means of
the mixture control screw (1). Turning
the mixture control screw clockwise
reduces the fuel quantity (lean mixture);
turning counter-clockwise increases the
fuel quantity (rich mixture).
ENGINE OIL
Checking engine oil level
Place the motorcycle in an upright
position and on a horizontal surface.
The engine oil level can be measured
with the oil dipstick. For this purpose,
