To adjust the drive chain slack
1. Place the ATV on a level surface.
2. Loosen the rear wheel axle pinch bolts.
3. Insert a rod of a diameter of 8 mm (0.3 in) and

A rod can be obtained at a Yamaha dealer to make
this adjustment.

To prevent this from occurring, keep the drive
chain slack within the specified limits.

pinch bolts to the specified torque in the order
shown.
