IDLE
Idle speed: 1300 (+/-100) rpm
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).
Note: by technical reasons and specific
carburettor adjustment, we highly
recommend that any intervention done
at carburettor should be done only by
an experient technician or at a AJP
dealer.
CLUTCH CABLE
Clutch cable must have a 10-20mm
free play. Clutch actuation must not be
affected by the complete turning of
handlebar to the top left or top right.
Keep always clean and lubricated
clutch cable for a smoother functioning.
Apply lubricant grease in the contact
area between lever and tuner.
Measure free play at the end of clutch
lever.
Free play: 10 – 20 mm.
Adjustment:
Smaller adjustment are made at lever
tuner.
Pull rubber protection out;
Untight fixation nut and rotate tuner;
When free play is right, tight fixation nut
and place rubber protection over tuner.
Check clutch functioning.
Whenever is needed to replace clutch
cable, use an original AJP cable.
Lubricate and install a new clutch cable
on the right position, in a way to avoid
bends that turn clutch harder to use.
Major adjustments are performed at the
tuner of clutch cable bracket (1).
