5. If distance A is incorrect, adjust it
as follows. NOTICE: Improper
drive chain slack will overload
the engine as well as other vital
parts of the motorcycle and can
lead to chain slippage or break-
age. If distance A is more than
58.0 mm (2.28 in), the chain can
damage the frame, swingarm,
and other parts. To prevent this
from occurring, keep the drive
chain slack within the specified
limits.

turn the adjusting nut at each end
of the swingarm in direction (b),
and then push the rear wheel for-
ward.
TIPUsing the alignment marks on each
side of the swingarm, make sure that
both drive chain slack adjusting plates
are in the same position for proper
wheel alignment.
