To the specified intervals in the "scheduled maintenance chart" (sect. 4 - 2) Check the coolant level contained in the expansion reservoir, on the right side of the vehicle.
The coolant level must be between the max. And min marks on the tank.
If the level is low, top up with the recommended coolant.
Remove the filler cap (1) and top up with new coolant to the specified level.
Refit the plug (1).

For optimal operating conditions (coolant mixture starting to freeze at -20 C), the recommended fluid antifreeze should be mixed with water in the following percentages: antifreeze: 35 to 40% of the volume; water: 65 to 60% of the volume.
Important
Very hard water with a high mineral salt content can damage the engine.
Increase the amount of antifreeze to up to 55% volume in the case of very cold climates.
Important
Solutions with less than 30% of antifreeze will not provide sufficient protection against corrosion.
Changing and cleaning the air filters
Changing the coolantRefitting the external components
Fit the cap (39) on spring (38) until it engages.
Mount ball (40), spring (38) with cap (39), washer (37) and screw (36) on the
chain side half-casing by starting the
screw into hole (f).
Note
The spring (38), with cap (39), must be oriented as shown.
Tighten the screw fully home to a torqu ...
Reassembling the water radiator unit
The procedure is the same for both radiators.
Check the presence of clips (1) at the positions of the external coolant
radiator cover (23).
If removed, fit the front turn indicator (32) on the cover (23) and tighten the
screws (27) to 2 nm +/- 10% (sect. 3 - 3,
Frame torque settings).

Adjusting the chain tension
Make the rear wheel turn until you find the position where chain is tightest.
Set the vehicle on the side stand. Push down
the chain at the point of measurement and release. Measure the distance between
the "aperture" upper profile and pin
centre.
The read distance must be: 9 to 11 mm.
