RE: Break-in Before Breathing Free?
With any luck by the time you pick the bike up, most of the serious break-in will have already been done for youby the dealer during, "Dealer Prep".
When the guy takes it out for its test ride, and opens it wide open a couple good times just after getting upto operational temp on its maddin drive out of the box!

This web link offers an interesting take on break-in regardless of the mods: http://www.mototuneusa.com/break_in_secrets.htm
It is sort of the science of ride it like you stole it.

Hey sgn, I'm with you on not changing her from stock until after break-in and wish I had waited. It's gotta be nice to feel that the changes have done something.

Any issues doing it right away (aside from the sucking sound on the 'ol bank account)?

Break-in is still break-in, whether you've got a 105" police motor, or a stage 1 96. Right?

And the debate goes on....
Doing Stage 1 is not an issue, just get the appropriate download. I've used a modified hard break-in approach myself that has worked well for me. The key is to vary the RPMs and never ever lug it. I wouldn't recommend engine braking for the first 500 miles either.

+1 That old way of breaking in engines is....well OLD. That way was good back in the days of very loose tollerances in the engine building process. So the piston rings had to find a "Seat" so that oil wouldn't blow by into the combustion chamber. Now, engines are built to very exact and close tollerances and the rings are seated and theengine is well on it's way to being broke in before they leave the plants(Assuming HD runs every bike on a dyno after assembly, which I am pretty sure they do).
Here's a very good read on the break in;

If you want it to run strong and not burn oil on down the road, run it like you stole it from the get go, vary speeds, take up fast and let off to seal rings, just dont overheat it. I wouldnt let some rookie tech dyno a new motor, I had rather be in controll of its break in. First 50 miles is the crutail period, after that whatever you do doesn't matter much.
