1. Place the motorcycle on the sidestand or a lift so that the rear wheel is elevated.	2. Rotate the rear wheel several times and check the drive belt to locate its tightest point.
3. Measure drive belt slack a ,using belt tension  gauge 1.	On the sidestand 7.5 ~ 13 mm at 4.5 kg (0.30 ~ 0.51 in at 10 lbs) On a lift 14 ~ 21 mm at 4.5 kg (0.30 ~ 0.51 in at 10 lbs)

Note: The level marks of the level window on the lower drive belt cover are in units of 5 mm (0.20 in).

Loosen the brake caliper bracket bolt 1. Loosen the wheel axle nut 2. Loosen both locknuts 3. A right side                B left side Turn both adjusting bolts 4 in direction a or b until the specified drive belt slack is obtained. Direction a: Belt slack is reduced. Direction b: Belt slack is increased. Tighten both locknuts to specification. Tighten the wheel axle nut to specification. Tighten the brake caliper bracket bolt to specification. Caution: A drive belt that is too tight will overload engine and one that is too loose can skip the pulley. Note: Measure the drive belt slack when the engine is cold.
