Removal of the fuel injectors

Operating on both intake manifolds, disconnect the connectors (n) that connect the main wiring to the injectors, loosen the fuel pipe retaining screws (p) and slide out the two injectors (3).

Removal of the fuel injectors


Refitting the injectors

Operate on both intake manifolds, check the presence of the o-rings (2) and (q) on injectors (3). Apply prescribed grease on o-rings (2) and (q) of injectors (3).

Insert the injectors in the relevant seats on the intake manifolds.

Important

To avoid damaging the o-rings, insert the injectors fully home on the intake manifolds by keeping them in line with the relevant seat.

Refitting the injectors


Operate on both intake manifolds, position the fuel pipes fittings on the injectors.

Important

To avoid damaging the injectors o-rings insert the fittings by holding them in line with the injectors.

Keep the fittings pressed on the injectors, then start and tighten the screws (p) fully home.

Tighten the retaining screw (p) to a torque of 5 nm +/- 10% (sect. 3 - 3, Frame torque settings).

Connect the main wiring connectors (n) to the injectors.

Refitting the injectors

If removed, insert the gaskets (15) in the seats (k) of the intake ducts (26).

Reassembly of the airbox - throttle body


If removed, refit the intake ducts (14) on throttle body (4) and apply prescribed threadlocker to the screws (5) and tighten them to a torque of 3.5 Nm +/- 10% (sect. 3 - 3, Frame torque settings) following the sequence indicated in figure.

Important

After tightening, visually check that the seals (15), previously fitted on the intake funnels, are still in their seats, and that the intake funnels are perfectly coupled with the throttle body.

Reassembly of the airbox - throttle body


If removed, refit the throttle grip cable as indicated: insert the opening cable (m) and the closing cable (h) in the corresponding plate seats (w) on the throttle body (4) as shown in figure.

Note

The throttle cables are distinguished by the writings in different colours on them:

Insert the bolts (t) in the corresponding seats of the pulley. Keep oriented as shown in figure, fasten the cables (m) and (h) inserting the nuts (l).

Tighten the nuts (l) to a torque of 2.5 Nm +/- 10% (sect. 3 - 3, Frame torque settings).

Fit the dust caps (v) on the throttle cable sheaths terminals.
