Vibration, tough to pinpoint

16k miles, Electra glide classic. In 3rd,4th gears, I can feel a subtle vibration between 2800 and 3300 rpm while rolling on throttle. It does not vibration when slowing down. At all other rpm's, its as smooth as it should be. It is under warranty, and dealer has had it twice for this specific problem, but they only tightened floorboard bracket and confirmed tires had right pressure. They will fix whatever is wrong, but they don't seem to thrilled about chasing this problem down.

I am looking for ideas on how I might better describe problem or perhaps something I might try to make it more obvious. All thoughts welcome.

I'm dealing with a very similar problem with my 09 flhrc. Although my rpm range
24-2500 ( all gears, all speeds)differs from yours. Started right after a rear tire change and
The rear drive belt was left way too tight. I took it in for this issue and they ended up
Replacing the inner main bearing in the tranny. Problem is, the issues I had complained
About originally are still there. ESP won't pay for diagnostic so since
I got dissed by the dealer, I called HD Canada and explained my problem to them.
RPM specific vibrations can be many things from engine mounts to engine crank run out.
To bad bearings in the tranny.

I called my Mom and told her the problems you guys are hav'in, she said....if ya can't find it yourself, then your going to have to wait until something shows itself more for them to fix it.

I've replaced the motor mount that was bad, packed and retightened the triple tree and serviced the forks. I still have it. My classic has 100600 miles.
