❱❘ Fitting the engine in the frame
To fit the engine in the frame, follow the reverse procedure, observing the tightening torques :
Engine screw: 40Nm
Swingarm spindle nut: 50 Nm
Clutch slave cylinder screw: 10 Nm
Cylinderhead-frame bracket: 23Nm
Exhaust nut: 10Nm
To withdraw the engine, you must remove the swingarm spindle, which allows pulling away the
rear wheel/swingarm unit. In order to prevent bike from falling, make sure it is held by the frame.
When the clutch slave cylinder is removed, the piston is no held anymore. Make sure it
remains stuck , using a zip tie, for example.
