To adjust the chain on your Kawasaki motorcycle or ATV, you will need a set of chain adjusters, a torque wrench, and a feeler gauge. First, place the bike on a stand or lift to raise the rear wheel off the ground. Then, measure the slack in the chain using the feeler gauge. If the chain is too tight, loosen the rear axle nut and use the chain adjusters to add slack. If the chain is too loose, tighten the adjusters to remove slack. Once the desired amount of slack has been achieved, tighten the rear axle nut to the manufacturer's recommended torque and check the chain tension again to ensure it is correct.
