Periodic maintenance and adjustment
1. Brake pedal free play adjusting nut
2. Loosen the axle nut.
3. Loosen the drive chain puller lock-
nut at each end of the swingarm.
4. To tighten the drive chain, turn the
7
drive chain slack adjusting nut at
each end of the swingarm in direc-
tion (a). To loosen the drive chain,
turn the adjusting nut at each end
of the swingarm in direction (b),
and then push the rear wheel for-
ward. NOTICE: Improper drive
chain slack will overload the en-
gine as well as other vital parts
of the motorcycle and can lead
to chain slippage or breakage. If
the drive chain slack is more
than 50.0 mm (1.97 in), the chain
can damage the frame, swing-
arm, and other parts. To prevent
this from occurring, keep the
drive chain slack within the
specified limits.
