CHAIN ADJUSTMENT
Chain should be checked, adjusted and lubricated as
per the Maintenance Chart to ensure safety and prevent
excessive wear. If the chain becomes badly worn or is
poorly adjusted (i.e., if it is too loose or too taut), it could
escape from sprocket or break.
Make sure that the chain features a slack (A) measuring
approximately 0.47 in., as shown in the nameplate (1)
on swingarm.
If it is not, proceed as follows:
- on the right side, with a 1.06 in. Allen wrench, loosen
the locking nut (1) of the wheel axle;
- loosen the check nuts (3) on both chain tensioners
and work on the screws (4) with a 0.39 in. wrench to
achieve the right tension;
- when the adjustment is completed, tighten the check
nuts (3) and the wheel axle nut (2).
After adjustment, always make sure that chain has a
slack of 0.47 in.
