How do you tighten chain on a 1991 polaris 350 L?

To tighten the chain on a 1991 Polaris 350 L, first, elevate the rear of the vehicle and secure it on a stand. Locate the axle adjustment bolts on either side of the swingarm; these are usually near the rear axle. Loosen the axle nut slightly and then turn the adjustment bolts evenly to tighten the chain to the desired tension, ensuring it has about 1-1.5 inches of slack. Finally, re-tighten the axle nut and double-check the chain tension before lowering the vehicle.
