Well crap that's what I was going to say. 
Three bikes would be ideal. Ultra modified demon soft tail or dyna, a road king with a 120r minumum and the SERG killed cat, easy pipes, high flow filter and tuner. Need more $!
The reason behind the thread is I have been questioned by the wife and a few guys about why I need so much power. I really have a hard time putting into words so I'd like others like me try to explain what I can't.
Is it something innately male that cries out for power, risk and danger? Stock bikes go the speed limit but why then am I not satisfied.
I saw one voter saying his bike was overpowered and I'd like to hear the rational.
Personally, I'd rather have an bike with power that I underutilize, than to be caught at a moment where I don't have enough. Maybe that's what drives my desire. However, I also realize that to push the limits comes with its own set of drawback. It's all about finding the balance that your comfortable with. As for buying a Hayabusa as mentioned above, I want one of those too. However, I won't get one till I know I won't just go out and just kill myself on it.
I decided to push the stock motor on my Limited for a few reasons. One it's not up to par with my lighter 110 based Springer. The other, the stock cams really suck the life out of it and it opens up way to high on the RPM range. By the time I'm ready to shift, the sucker takes off like I hit a NOS button or something.
So, I decided to change the cams, but had to think about the implications to the warranty - not the rest of the bike per se, but the actual part I was replacing. Turns out my extended warranty will cover all HD parts, so that made my decision easier, but narrowed my choices. Then after researching the cams, decided to go with the SE259E based on data I gathered and riding up against a bike that already had them installed.
Worked for me, but there was a caveate. In order to really make the SE259E work well, I had to bump the compression. So again, options, warranty considerations, and parts that work together narrowed my choice down to the SE Stage III kit. All of the new parts covered by extended warranty, the rest of the bike covered by both initial and extended warranty.
Even if it isn't the best configuration I could go with, it will be by far better than the stock motor/cam set, and hopefully not exceed the stock 110 in my springer too badly. Then I'll want to upgrade it.

Also, I just saw a brand new RG that had a 120R dropped in, with all the other goodies added like new custom tank, seat, etc. Very very nice! Cost the new owner $21k over the price of the bike to get everything done. Guess he still got a lot of extra cash flow.
