My 2012 came from the factory without a riveted master link. If that is not endless, I don't know what is. I hope that something on the swing arm is accurate during chain adjustment. I eyeball mine using the mark points and justify that with vernier calipers.
There is a riveted master, but the factory uses a air-powered riveter than has a head exactly like the one that puts the links together at the chain factory, so they all look the same. Chain is made in lengths, cut to suit and riveted into the proper-sized loop.
Eyeballing is great for shooting pigeons, but it won't align the wheels and neither will the marks on the swingarm. And neither will a vernier caliper unless it has 6' jaws.
For the wheels to be aligned, the front wheel has to be perfectly centered. Then, checking to two long straightedges to the rims (not the tires), the measurements front and back of the back rim on both sides must all be the same and the measurements to the front and back of the front rim must be that number minus 50% of the difference between the wheel widths. Once you have the back 4 measurements the same and the front 4 the same minus 1/2 of the difference between the wheel widths, your wheels are in alignment. At that point, you can adjust the chain slack properly by counting flats on the adjuster bolts to keep it the same side-to-side. Going by the marks on the swingarm is a crapshoot, and you'd be surprised to find out how far off some are.
