Quite a few folks on the forum have noticed it, including myself. Mine has done it since new. I suspect it's a lean condition, most likely related to emission control. On my bike it's roughest about 1800-2K rpm then disappears above that.
I created a post about the fuel injection problems I am experiencing with my 2014 CB1100 here a few months back. I have not kept it up-to-date, but in summary:
1. The throttle bodies on my bike are not synchronized - I posted a picture of the electronic vacuum gauge reading on this forum.
2. My bike has been returned to the dealer four times - the Honda mechanics claim it runs "fine" - it does not.
3. An electronic diagnostics test has been performed by Honda twice - both times the results were satisfactory.
4. Below 3,000 RPM and at very light loads my bike runs poorly - you can hear it mis-firing.
5. From stoplight to stoplight (one block apart) my bike is annoying to ride. My bike has somehow, mysteriously been running better as the miles have increased (3,000 miles now) - but it still does not run acceptably.
6.On the back roads, in corners, where you let the RPM drop below 3,000 is where it is most noticeable - and annoying. The engine stumbles (slightly) as the throttle is applied below 3,000 RPM, then suddenly comes to life above 3,000 RPM (actually closer to 3,200 RPM).
7. After four visits to the dealer, multiple phone calls to the factory and a threat to invoke the California Lemmon Law, Honda is arranging to have a "factory representative" present when Honda can perform their own vacuum test.
8. I love my bike, and if Honda cannot / does not repair it to my satisfaction then I will repair it myself - contrary to common belief the throttle bodies can be adjusted. I am convinced that synchronizing the throttle bodies on my bike will improve its performance (I have years of experience synchronizing carburetors on 4-cylinder bikes).
Or- the built in cam timing cylinder differences....
