Congratulations!
Compared to the Sportster, your RSV is going to feel a little sluggish off the line, but throttle response at highway speeds will surprise you. Keep in mind, you don't want to ride it like a Harley. Keep the RPMs up until you are at cruising speed. Then remember you will want to down shift for jack rabbit passing. It will lug out from low RPMs but she'll complain about it!
Oh yeah, DO NOT USE V-Twin oil in her! The wet clutch doesn't like friction modifiers. Some of the cool kids run Rotella maybe with some Lucas additive.
BTW,
