If the question is how to adjust the drive belt, it's actually pretty easy. With the bike in the side stand you should have about 1/4-3-/8 deflection in the middle of the drive belt pushing with 10lbs of pressure. The best thing to do is purchase a drive belt deflection tool that you can set to 10lbs. If you need to adjust the belt, you loosen the axle nut on the right side and turn the axle from the left side to loosen or tighten the belt tension (Harley uses eccentric shaped washers on both sides of the axle to make this adjustment easy). Once you made the adjustment and tightened the axle nut, double check the deflection to make sure it didn't change while tightening the axle nut. Takes about 10 minutes to check and adjust.
