Refitting the exhaust system

Position the vertical exhaust manifold (14) on the vertical cylinder head with the gasket (4).

Tighten the fixing nuts (3) to a torque of 10 Nm ±10% (Sect. 3 - 3, Frame torque settings).

If removed, tighten the vertical lambda sensor (12) to a torque of 24.5 Nm ± 10% (Sect. 3 - 3, Frame torque settings).

Position the horizontal exhaust manifold (11) on the horizontal cylinder head with the gasket (4).

Tighten the fixing nuts (3) to a torque of 10 Nm ±10% (Sect. 3 - 3, Frame torque settings).

If removed, tighten the horizontal lambda sensor (12) to a torque of 24.5 Nm ± 10% (Sect. 3 - 3, Frame torque settings).

Position the catalytic converter (24) and operating on the left side of the vehicle, insert the screw (22).

Holding the catalytic converter, operating on the right side of the vehicle, insert the screw (22).

Position the two fixing springs (13).

Tighten the two retaining screws (22) to a torque of 10 Nm ± 10% (Sect. 3 - 3, Frame torque settings).

Position the control cable (20) in the plate (B).

Turn the exhaust valve pulley (A) to facilitate the throttle grip cable (20) introduction.

Tighten the fixing nut (C) to a torque of 2.5 Nm ± 10% (Sect. 3 - 3, Frame torque settings).
