Secondary drive chain adjustment

Chain should be checked, adjusted and lubricated as per the "Maintenance
Chart" (see Section B) to ensure safety and prevent excessive wear. If the chain
becomes badly worn or is poorly adjusted (i.e., if it is too loose or too taut), it
could escape from sprocket or break. To adjust chain tension, you need to lower
the rear end of the motorcycle so as to bring the axes of rotation of sprocket,
swinging arm and rear wheel into alignment as shown in figure "A", and then
turn the rear wheel three turns. In this condition, the chain should be neither
taut nor slack. (Fig. A).
Quick adjustment (Fig. B)
Insert, at a distance of 145 mm (5.7 in.) from the fork centre, a bushing (a) with
a 35 mm (1.37 in.) diameter (as an alternative, insert a spacer of the same
dimensions) and make sure that the lower arm (C) of the chain is slightly tight.

If it is not, proceed as follows:
- Loosen the wheel axle nut (1) on the right-hand side using a 27 mm socket
wrench;
- Loosen the check nuts (2) on both chain tensioners with a 12 mm wrench
and work the screws (3) until achieving the correct tension;
- When the adjustment is completed, tighten the check nuts (2) and the wheel
axle nut (1).
After any adjustment, always check wheel alignment and tighten wheel axle
securely (142.1 Nm - 14.5 Kgm - 104.8 ft/lb).
