I recently purchased a 2011 Concours 14 with very low miles. The bike does not want to pull up thru the RPM range in the upper gears. It isn't missing or stumbling, but acts like it is running out of fuel. Has anyone else experienced anything like this?
One of the only common issues with the c-14 is fuel pump / fuel filter issues. Your issue sounds typical.
Word to the wise, the Quantum pumps seem like a great value, but I have seen several instances where folks had to replace the new pump 2-3 times and still have issues. In each case an OEM pump solved the problem.
This has been a not uncommon problem. In many cases a new fuel sock solved the problem. Quantum sells them in a 3-pack.
How many miles on your 2011 ??
Here is a pic of my old fuel sock ( on right, of course ) next to a new Quantum fuel sock @ less than 20K miles on my 2008. The old fuel sock was coated with some build-up. I wasn't having a problem, but replaced the sock after reading about the problem on this Forum. I was doing the 20K mile service.
I don't see why you couldn't measure the flow with the old sock and then new sock. If you see a big change, the pump is probably OK.
The fuel pressure regulator could be a possibility, too. It's part of the fuel pump assembly.

I will preemptively change my sock soon - 17’ with mid 40’s-K miles. Not a lick of trouble here; however with more than 1,000 gallons of fuel having flowed through - undoubtedly there will be some ‘patina’.
