I don't think you can get it factory installed, but you could try calling the USA headquarters and ask them if they will arrange for that. But usually they want the dealer to do it in order to give them the profits and keep them happy. The storm will be a cheaper way to get the 1700 unless you can fenagle a great deal on the bike and kit+labor from your dealer.
As to break in, i don't know, but i can't imagine why it would matter either way. But considering it's only 600 miles for the initial break in period i think you can wait.
Congrats....you will love the bike. I had a speedmaster and going to the Tbird felt like going from a toyota corolla to a porsche, not just power wise but quality, features, everything.
