Kawasaki Ninja Service Manual: Drive Chain Slack Adjustment

• Remove the cotter pin [A], and loosen the rear axle nut [B].
• Loosen the both chain adjuster locknuts [C].

If the chain is too loose, turn out the left and right chain adjusters [D] evenly.

If the chain is too tight, turn in the left and right chain adjusters evenly, and kick the wheel forward.

• Turn both chain adjusters evenly until the drive chain has the correct amount of slack. To keep the chain and wheel properly aligned, the notch [E] on the left wheel alignment indicator [F] should align with the same swingarm mark or position [G] that the right indicator notch aligns with.

• Tighten the both chain adjuster locknuts securely.
• Tighten the rear axle nut.

Torque - Rear Axle Nut: 127 N·m (13.0 kgf·m, 94 ft·lb)

• Turn the wheel, measure the chain slack again at the tightest position, and readjust if necessary.
• Insert a new cotter pin [A].

NOTE

• When inserting the cotter pin, if the slots in the nut do not align with the cotter pin hole in the axle, tighten the nut clockwise [B] up to next alignment.
• It should be within 30 degrees.
• Loosen once and tighten again when the slot goes past the nearest hole.

• Bend the cotter pin [A] over the nut [B].
