Kawasaki Ninja Service Manual: Balancer Adjustment

• Remove the left lower fairing (see Lower Fairing Removal in the Frame chapter).
• Start the engine and warm it up thoroughly.
• Adjust the balancer gear backlash with the engine idling.

  The amount of backlash can be changed by turning the balancer shaft which has eccentric journals.

Start the engine and let it idle.

Loosen the clamp bolt [A] and turn the balancer shaft [B] clockwise [C] until the balancer gear makes a whining sound.

Turn the shaft counterclockwise [D] until the balancer gear whining sound disappears and tighten the clamp bolt.
