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. (30 mm) diameter (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 1.06 in. (27 mm) Allen
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), coupling torque 22 Nm / 2,24 Kgm / 16,23
ft/lb), and the wheel pin nut (1) coupling torque
142 Nm / 14,48 Kgm / 104,73 ft/lb).
When the adjustment is over check the wheel for
alignment.
