THROTTLE BODY "2"

The quantity of intake air is determined by the opening of
the throttle positioned on the initial part of the intake
manifold on every cylinder.
The air necessary for running at idling speed flows through
a by-pass channel, equipped with an adjusting screw:
turning this screw will vary the quantity of air which is
introduced into the manifold and consequently also the
idling speed.
A second screw allows the throttle closing to be adjusted
correctly. This will avoid any interference with the
surrounding duct; this screw must not be used to adjust
the idling speed.
Disassembly:
• Remove the air filter box as described in chapter 8 of
this section;
Disconnect the following from the throttle body:
• The potentiometer wiring;
• The wiring on the injectors "A";
• The accelerator control transmissions;
• The choke control transmission as described in
chapter 4 section G;
• The fuel delivery and return piping;
• Remove the throttle body from the motorbike.
IMPORTANT
Plug the intake manifold ducts to prevent foreign
bodies from getting into the combustion
chamber.
Reassembly:
• Carry out the procedures in reverse order.
