Well that is a big suck.
I did the same thing road racing (except assisted by a thoughtful Ducati, which ran over me).
I had to have a plate and screws put in -- apparently, the collar bone acts like a fulcrum for one particular muscle, and when the bone is fully separated like that, you have to have surgery to get the muscle back on the correct side of the bone, and to affix the bone.
Don't worry, you'll be fine.
When they say Harleys are for 1%ers, I don't think they mean guys who sell crank and get in bar fights any more.
