Like I said put chain on sprocket and see how far it pulls away .. at the back Installed.  Or just wrapped around a sprocket.
 I a d many others cat see chain wear in a pic   dirty or clean.

I finally looked at your pic.. usually a serviceable chain and new look pretty similar..
 Before we try to tell you the obvious m try answering these questions.
 Do you think the peened link being tight, May have something to do with being peened to far....i.e. tight.?
 Do you think its ok to have cracks in your sideplates.  .?
 DO YOU THINK IF THERE IS WEAR   on the inside of your chain links that it is supposed to be like that ?

I do think the tight link is probably the one that was making noise although I haven't marked it and reinstalled it to be sure. I don't know how the link could get that wear on it, especially on only one or two links. I thought maybe someone would know. I am buying a new chain now and hopefully that will run smoothly. I have been waiting to install exhausts/start the bike due to this chain issue (can't torque axle with exhaust on).

Yea, new chain time.  I would carefully inspect the sprockets.  That bound link may have ruined the sprockets as well if it was run on them for any length of time.

 Again, (if only to learn something ) put chain on sprocket and try to pull it away.
 When you get a new one, take a mental not of what it looks like when you pull on the chain.

 With a new chain or piece of chain, test the sprocket,  put chain on  then try moving it against the teeth, if everything is good it will barely move.

If you get a too long chain and trim it, keep that piece in your tool box to check chains and sprockets.
 Up to you now to try lifting chain from sprocket to test it.

I tested the old chain, it was able to pull away from the sprocket a bit but not quite enough to see light come through. I ordered a 530P 100L DID chain, will install when it comes on monday or tuesday.

Just installed the new chain and it rolls smoothly. So that fixes that. However once I put the sprocket cover on, the chain rubs on the part shown below, some kind of chain guide I’ve not seen on other bikes. When I put the bike down off the center stand it doesn’t rub. But when the wheel is free hanging it rubs. What gives? Is this normal?

Looks to me like spacer #7 is missing. Hard to tell. But if it is, you'll do some damage. That spacer goes to the inside race of the left bearing. Better pull the wheel and take a look.

No the chain is rolling fine, I don’t think the wheel was out of alignment after all, just the kinked chain causing it to walk sideways over the sprocket as it seated.

Now it’s like the wheel is too low (chain hits the part inside the cover even when way too tight). If I put load on the wheel (compress springs slightly) the chain doesn’t hit anymore.

That’s what I was thinking too. I didn’t measure the shock length yet. The tab that’s rubbing goes under the chain. The tab is removable with a couple m6 bolts. Can I just take it off?

I'm trying to find the shock length for the 550 listed online. The shocks on there look stock, but maybe the front end rake is having an effect. I have a nice set of 400 shocks that I'm not using, if they're a little shorter maybe I can use them ;)
