To adjust the chain tension on a Sportster, first, place the motorcycle on a flat surface and secure it on a stand. Locate the chain adjusters on each side of the swingarm; loosen the rear axle nut and then turn the adjusters evenly to achieve the desired tension, typically around 1 to 1.5 inches of vertical play in the chain. After adjusting, re-tighten the axle nut and double-check the tension before taking the bike for a ride. Always consult the owner’s manual for specific guidelines related to your model.
