SETTINGS AND ADJUSTMENTS
Secondary transmission chain adjustment
Chain should be checked, adjusted and lubricated as shown on the Mainte-
nance Chart (page B.5-B.8) 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. Then let turn three times the rear wheel. Now the chain
should not be tight. (Fig. A).
Fast adjustment (Fig. B)
Insert a bushing (a) with a 35 mm diameter (or with the same thickness) as shown
in the image and make sure the lower section (C) of the chain is slightly taut.
If this is not the case, proceed as follows:
- loosen the nut (1) of the wheel axle on the right side with a 27 mm Allen wrench;
- loosen the check nuts (2) on both chain adjusters with a 12 mm wrench and act
on the screws (3) until the proper tension level is restored;
- once tension has been adjusted, tighten the check nuts (2) and the wheel axle
nut (1).
After the adjustment, always check the wheel alignment and tighten the wheel
axle fully (142.1 Nm- 14.5 kgm- 104.8 ft/lb).
