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 bad-
ly 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), 1.37
in. (35 mm) (RS) and 1.18 in. (30 mm) (SM) diameter

sure the lower branch (C) of the chain is slightly
taut.
If it is not, proceed as follows:

screwdriver, loosen the locking nut (1) of the
wheel pin;
- with a 0.47 in. (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
