Hi Sportster Doc. I am going back and re-reading all the trouble-shooting posts and wanted to comment on the fact that your 2014 standard TPS part number is JT6H 40226, while my 2014 Dlx part number is JT6H 40116. I wonder if this means anything (Honda upgraded the sensor at some point?).
...Then, while I was cleaning electrical connections, I remember that I was using a cheap battery from Autozone and decided to replace it with a motobatt battery. ... I waited 3000 miles to report my problem/solution just to make sure the problem was solved. I know that my case can be an isolated case but hopefully it helps someone one day. cheers.
I replaced my battery with a new YUASA battery and it did not cure the idle problem.

The Keihin JTG6 for sale on the web all have different 5 number suffixes, if the suffix is even listed.
Google 16402-RAA-A01 for Honda CR-V 2.4 liter or
16060-MBZ-A11 for 2006 Honda CB600F
At this point I do not know the significance of the suffix or if it has any significance.
AFAIK all TPS, including automotive, are powered by 5 VDC and send out ~0.5 VDC at idle and ~4.5 VDC full throttle.
The mounting slots appear the same and the connection to the throttle body shaft appears to be the same.
Your mission, should you chose to accept it, is to get suffix educated...if it matters.
Meanwhile if the electrical connector pins are all seated in each housing cavity, contact mating surfaces are clean, then electrical tests of the TPS should be done before purchasing a replacement.
Pages 5-23 thru 5-25 of the FSM cover full diagnostics, but a Honda instrument is required for some testing. Max's video will tell you a lot.

Max has been corresponding via PM with several posters, to gather data.
I posted a summary on Dec 27 (post 651) with earlier info in posts 615 and 618 (page 62) and 622 (page 63).
At this point, a conclusion requires test results. I continue to expect that this is not just one issue: A check for vacuum leaks and loose connections is a good start.
BTW, the Yamaha dealer found a home for my Moto Guzzi V7II.
Youngster from New York was looking for one.
It sold for what I was credited...dealer did not profit or lose...other than selling me the 2018 Yamaha XT250.
Ridden at the same speeds, my CB1100 at 1140 cc, is getting about the same MPG as the 744 cc V7 II.
On this forum, how many CB1100 have an unsolved idle?
Max, what is your tally?
