I noticed a small leak coming from above the very rear heat exchanger. I am hoping that it is from a clamp. If I take the flap off, will these clamps be exposed?

No clamp back there, solid piece. Take off cover/flap and check it out, should be easy fix with a good welder guy.

I see that now. I thought the very back piece was separate, but now I can tell it is all one piece. Do you know if this is a common fail point? The leak is coming from above the hx.

Haven't seen anything on it, get it apart is all you can do.

I found a very similiar leak on my 2014. Started as a static leak this summer. On a 200 km ride I might loose a tsp of coolant. I just tried sealing it with JB weld SteelStik and 500 km latter it is still fine. I know welding is the best option but the hole was smaller than a pin head and the pressure won't exceed 16 psi so I thought I'd give this a try.

The picture you show of the weld bead shows an addition bead at the end. The weld beads did not fuse properly. So you have a tight seam that the coolant is leaking through. The correct way to fix it is to TIG weld it with the coolant out of it. It is in a tight spot and a 2011. I'd try the epoxy first. Carry some extra coolant when you ride too. I have heard of other people having good success with epoxy, even from stud damage.
