I just came off a long trip bringing my total miles to 3,500. I noticed the low-rpm "growl" quite a bit. Didn't sound bad - just noticed it under the same conditions you've described. I'm coming off a cruiser and 3k rpm sounds very comfortable to me and I'm having difficulty running the bike consistently at higher rpms. I'll admit the bike seems very happy at 4k and I need to work mentally to keep it up there.
