I put ~40,000 miles on my SE Stage 1 oil cooled 107 which ran spot and I now have put on over 56,000 miles on my stock oil cooled 114..the 114 is an all around a better performing powertrain
I have the same opinion as MJ. We has a couple 107's. Mine had the stage 2 kit, with S&S 465 cam. When i test rode the stock 114, they were very close in performance. The 107 was a little more responsive down low, but the 114 wasnt long being right there. The 114 is every bit as smooth, as the 107 or smoother IMHO.

what became very apparent to me early on is how the 114 didn't run out of breath the way the 107 did in the taller gears pouring the coals to it uphill
2017 RGU 107 2020 RGL 114.
Both severe well. Not a dam thing bad to say about either.
At first the 114v seemed off to me. After a few miles it seemed to me the 107 was a big stronger on low end. And the 114 shined a bit brighter on the higher end.
I suspect, as already mentioned here, the real difference you are noticing is the rubber mounted engine in your Road King vs the rigid mounted engine in the Fatboy.
They ride and feel like completely different animals in terms of engine feel.
Years back, I traded my Electra Glide Standard in on a new Fatboy (both were early twin cams but same general engine mounting configuration).
Loved the looks of the Fatboy but missed the handling and shaking at idle (which magically transformed into incredibly smooth while under way) power of the rubber mounted engine in the Touring chassis.
Fast forward nearly 25 years and three more Harley motorcycles later, every Harley I have owned since selling the Fatboy has been a rubber mounted touring model.
