You've welded extensions on, you can see the left hand weld just to the right of the left hand brake reservoir. The light is reflecting differently showing where you've ground the welds down and painted over, and you can see the very slight change in angle of the bars, where you haven't gotten the extension exactly in alignment.
I hope you either put another rod inside to support the extension or these are just for show, the bar wall thickness wasn't designed to have the weight loading so far from the attachment point.
