Adjust the chain by sighting from the rear along the top of the sprocket down the chain. It should appear straight. Or you can get a Motion-Pro chain adjust tool - nothing more than a little clamp w/ a long rod that lies along the top of the chain when the clamp is placed on the rear sprocket. This makes aligning the rear wheel very easy. Using calipers and adjusting by measuring the distance from the end of the swing arm is not the correct way to do this. As said above, the markings are only guide and cannot be trusted. Similarly, the swing arm legs might not be the same length or the caps might not seat properly.
