Thjese are typical symptoms of new HDs. I don't experience that quite as much because I have a big SEL, much heavier, and this dampens the shocks somewhat.
Yes, I think it will settle with time. Drive on it.
By the way, go for a nice long (200 miles plus) high speed highway jaunt. After a while, the gas in these HD's pressurizesd to the point that you're like riding on firm air - a most exhilarating feeling, almost nirvana-like. They won't do this on short around-town trips, but will excell under the conditions I've noted.
