CHAIN ADJUSTMENT (Fig. A)
Chain should be checked, adjusted and lubricated as per the
Maintenance Chart to ensure security and prevent excessive
wear. If the chains becomes badly worn or is poorly adjusted
(i.e., if it is too loose or too taught), it could escape from
sprocket or break.
To adjust the rear chain it is necessary to lower the rear part of
motorcycle so to line up the drive sprocket axle, the rear swing
arm axle and the rear wheel axle as shown on drawing. Than
let turn three times the rear wheel. Now the chain should not
be tight.

Fast adjustment (Fig. B).
In the point shown in the figure, fit a bush (a), 35 mm diame-
ter (or alternatively a shim in the same size) and make sure
the lower branch (C) of the chain is slightly taut.
If it is not, proceed as follows:
- on the right side, with a 27 mm Allen screwdriver, loosen the
locking nut (1) of the wheel pin;
- with a 12 mm screwdriver, loosen the check nuts (2) on both
chain stretchers and work on the screws (3) to achieve the
right tension;
- when the adjustment is over, tighten the check nuts (2) and
the wheel pin nut (1).
When the adjustment is over check the wheel for alignment.
