This is commonly caused by reversion, most affected by the design of the exhaust. On Harleys and Buells, reversion is almost always present around 2800 to 3300 RPM when a 2-1 exhaust is used. My Buell in particular has a very noticeable drop at those RPM.
No, only reved up to about 3000 RPM. In ref to my exhaust, I have a single pipe (inlet) to a Flowmaster Super 10, then dual exit (outlet) for the tailpipes.

In the spring I'll double check a few things and experiment with the timing as described by turbobill in a prior post, then run it on the dyno again and run the RPM up a little higher. I'll let you guys know what the results are.

Thanks for the feedback.
