Clearance between the clutch drum and friction plates
Insert a friction plate (e) in the clutch drum (f) and measure the clearance (s) with a feeler gauge.
Clearance "s" must not exceed 0.6 Mm.
If it does, renew the plates and, if necessary, the clutch drum.

Overhaul of the clutch plates
The clutch plates must not show any signs of blackening, grooves or deformation.
Measure the thickness of the friction plates; it should not be less than 2.6 Mm.

Important
The total thickness of the discs pack must not be less than 46.1 Mm.
Place the plate on a flat surface and check the amount of deformation with a feeler gauge.
Max. Flatness error: 0.2 Mm.

Overhaul of the pressure plate
Check bearing (5) condition; renew the bearing if the play is excessive.
Check the contact surfaces of the last friction plate; if extremely scored, polish it in the same manner as described previously for the cylinder head surface (sect. 9 - 4.5, Overhaul of cylinder head components).
Check conditions of the spring guide bucket tappet (g) of the pressure plate (4) and of the circlips (6).

Overhauling the pressure plate springs
Measure the length "l" of each spring (3).
Minimum length: 41 mm.
Renew any springs that are shorter than the above limit value.

Removal of the clutch
Reassembling the clutchRefitting the gear selector lever
Position the gearbox drum selector fork in the centre of the gear rollers.
Position the gear selector lever (21) together with control shaft, spring and
plate into the chain-side crankcase half.
Insert the screws (18) and (20) with the spacer (19).
Temporarily fit gear change lever (or a ...
Refitting the expansion tank
If the support (15) has been removed, place the hose clamps (14) on the
bracket (15) orienting them as indicated.
Fully press the pins (a) to block the clamps (14) until pins surfaces (b) are at
the same level of the clamps (14) surfaces.
Apply recommended threadlocker to the thread of the ...
Lubricating cables and joints
Check the outer sheath of the throttle control and cold start
lever cables for damage at regular intervals. The outer plastic
cover should not be flattened or cracked. Operate the
controls to make sure the inner cables slide smoothly inside
the outer sheath: if you feel any friction or catching, ...
