Kawasaki Ninja Service Manual / Periodic Maintenance / Periodic Maintenance Procedures / Final Drive / 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.
