I am posting this so others don't repeat the mistake I made. When reinstalling the rear wheel ensure the rectangular axle blocks are oriented the correct way - so the indicator lines stamped on one side are vertical and facing outward.
Dooh! I guess I was not wearing reading glasses or was rushed and somehow did not notice this when installing the rear wheel the first time. This put too much tension on the chain and put significant wear on the sprockets in the ~300km I drove the bike this way. I am keeping my fingers crossed I did not damage the bearing on the drive sprocket.
On a related note, checked the rear wheel alignment with string after setting it by the marks on the swing are and was ~30mm out (measured at the front wheel from string). It looks like the swing arm marks are only helpful in getting you in the right ball park but are far from accurate.
I agree about the lines on the blocks. Even if they get turned upside down, they are off. I just run the chain and adjust it so it wanders back and forth on the rear sprocket like I would anything else (snowmobile track comes to mind) with the tension correct.
This is the only way I can be sure.

What do you mean by facing forward? the blocks look symmetrical I don't see any indicator as to whats forward or back. I always measure from the center of the axle shaft to the foot peg mount for alignment.

For my previous bikes, using digital calipers, I measure the space between the swingarm and the axle block.
I don't trust the indicator marks for alignment. My bike is still on its stock tires and the indicator marks are not the same for the left and right side.
Run your bike on a stand. If the chain runs to one side of the rear sprocket, the wheel alignment is off. It should wonder back and forth on the sprocket. Then the wheel is straight.
String, calipers, tape measure or laser. Just run the bike and watch the chain.
My rear wheel was off by a lot when I bought the bike new. It also only had 22 psi in the tires. They had me sign a paper saying they did all the predelivery stuff to the bike. I didn't figure out about the tires and crooked wheel until after the first day I had the bike which was a 400 mile ride on back roads to break it in.
