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.
