If interventions have been carried out on
the throttle bodies, the transmission of the
throttle control must be analysed not only at
the throttle control handgrip but also near
to the throttle bodies.
It is therefore necessary to consult chapter
D “Air intake injection system”.
As a final control and after having reassembled all the
components, switch on the engine and check that, with
the choke lever activated, the tickover of the engine
does not exceed 2500 r.p.m.
Maintenance
After making adjustments, check that the throttle
valves open slightly by activating the choke lever (1) as
indicated in the following figure.

THROTTLE CONTROL
(F4 MY10 -> MY12)
Throttle control play check
g
At the pre-delivery check,
at the first 1000 kilome-
tres and then every 6000
kilometres.
The throttle control should not be too tight or too slack
(excessive play) in its movement.
It must also be free of play and looseness when turning it.
For optimum adjustment it is necessary to work on the
two upper nut adjusters (situated on the throttle control
handgrip).
The lack of play on the closure of the throt-
tle control (1) can stop the complete closing
of the throttle valve and the throttle control
could remain in the open position, thereby
leaving the engine with a fast tickover.
