To adjust the drive chain slack
Consult a Yamaha dealer before ad-
justing the drive chain slack. 1. Loosen the axle nut and the lock- nut on each side of the swingarm.
2. To tighten the drive chain, turn the drive chain slack adjusting bolt on
each side of the swingarm in direc-
tion (a). To loosen the drive chain,
turn the adjusting bolt on each side
of the swingarm in direction (b),
and then push the rear wheel for-
ward.
TIPUsing the alignment marks and notch
on each side of the swingarm, make
sure that both drive chain pullers are in
the same position for proper wheelalignment. 3. Tighten the axle nut, then the lock-
nuts to their specified torques.
4. Make sure that the drive chain pull- ers are in the same position, the
drive chain slack is correct, and
the drive chain moves smoothly.
