Apply the recommended grease to the thread of the pins (9) and of the nuts (8).
Place the frame (1) and the brackets (2) and (3) on the engine block. Start the pins (9) by holding the nuts (8) and insert without tightening the screws (6) into the adjusters (4).
Position and fix the rear shock absorber support to the engine crankcases and the swingarm brackets (sect. 7 - 12, Refitting the shock absorber support).
Tighten the screw (v) on the swingarm shaft right side to a torque of 72 nm +/- 5% (sect. 3 - 3, Frame torque settings), by holding the screw (z) on the left side.
Tighten the indicated front nut (8) to a torque of 60 nm +/- 5% (sect. 3 - 3, Frame torque settings), by holding the pin (9) on the left side.



Reassemble the tool tray (23), as described in the following paragraph, by tightening the rear screws (24) to 14 nm +/- 5% (sect. 3 - 3, Frame torque settings).

Tighten the indicated rear nut (8) to a torque of 60 nm +/- 5% (sect. 3 - 3, Frame torque settings), by holding the pin (9) on the left side.


Work first on the left side and then on the right one, remove the special screws (6) and tighten to a torque of 0.5 Nm +/- 10% (sect. 3 - 3, Frame torque settings) the adjusters (4) and make sure they are fully home on the rear plates of the rear subframe.
Locate service tool no. 88713.3166 On the ring nut (5) and fit the torque wrench to the tool.
Hold the clearance adjusters (4) and tighten the ring nuts (5) to a torque of 100 nm +/-5% (sect. 3 - 3, Frame torque settings).
Lubricate thread and underside of special screws (6), then start them on the frame, and tighten them to a torque of 55 nm +/-5% (sect. 3 - 3, Frame torque settings).



Tighten the front screws (24) to a torque of 14 nm +/- 5% (sect. 3 - 3, Frame torque settings) that retain the tool tray (23).

Reassembly of structural components and the frame
Reassembly of the tool trayRefitting the oil pump
If removed, apply specific threadlocker on the bushing (7) outer thread, and
screw it in the crankcase half, observing the
height.
Position the reference bushings (15) and the oil sealing o-rings (2) and (4)
according to the crankcase lubrication
channels.
Position the oil pump on th ...
Cylinder compression test
Note
The on-screen icons used during this procedure are explained in a table at
the end of this section.
Engine performance is directly correlated to the pressure that can be
measured in the combustion chambers of the two
cylinders. Pressure which is too high/low or an excessive difference be ...
Removal of the generator cover
Note
This operation is described for an engine removed from the frame since all
reassembly procedures are easier with the
engine on the bench.
Disconnect the connector (a) from the generator cable.
Unscrew the two retaining screws (7) of the centre cap (6) over the end of
the cranksh ...
