As mentioned by Don (Deweysheads), making big power without upgrading the bottom end will probably be a serious mistake. The current Harley crankshaft is a weak link, and I wouldn't invest all that time and money on the top end without fixing the bottom end first. And don't forget the primary components, the weak clutch, and the marginal trans.
If you really want crotch rocket performance with reliability, I suggest you stick with one of the excellent products from Honda/Yamaha/Suzuki/etc. On the other hand, if you don't mind breaking stuff all the time, then by all means go for the big numbers on your Harley. Probably be a good idea to have a chase truck when you go for any long rides, however. Like tennisman mentioned, it's a touring bike, not a racer. Since you are fortunate enough to have a touring bike and a crotch rocket, it looks like you just need to decide in the morning if you prefer to cruise in comfort, or go out and burn up a tire, and then pick the appropriate bike to take.
