Yeah, those pics probably gave Idodirt a heart attack.

Do you're chain adjustments again. Clean it & lube it to. I reckon that its still to tight & the noise is the tight spot going over the sprocket (kachunk, kachunk).
All chains stretch unevenly, what you have to do is find the tightest spot between front & rear sprockets & adjust it there. just remember there is always going to be more that one tight spot (but 1 will be tighter than the rest.
Adjust the chain so that the marks on the swing arm are aligned (not 100% accurate) but a good place to start.

 

That adjuster looks pretty far back indicating a worn set of chain and sprockets. Change it before disaster happens.

 

This is how you determine your chain is garbage....Put the bike up on a swingarm stand/ or jack. Spin the wheel. find the loosest chain slack you can while turning the wheel. If you adjust the wheel to fix that and bring the chain slack into spec, then rotate the wheel....if the chain tightens more than what you just set the slack at, scrap everything and put on new sprockets and chain. Very simple to see in your garage. The worn chain is your culprit.
