It might be OK. Check the front isolator.
I just got a 05 XB9 and notice when it ildes down, right around 2k there is a noticeable increase in vibration for a couple of seconds. Is this the same issue you were having?

Some Harley Davidson stores, eBay, google it.
Well it looks good. So now what else could be making those vibrations?
I have the same issue with the vibrations when the RPM is on the way down at about 2000 RPM. Just bought the bike, and it is my first Buell, also the first bike with a H-D engine.
It's normal for every XB I've had, and I've had quite a few. It's a lot of heavy rotating mass to control at every RPM. Just ride it
