I'm ok with not having a ton of power. My car is my hot rod right now. Crazy idle lope and tall gears are fun around the street. I just want a little more power for my bike and better fuel economy than my car.
I was thinking about the Fuel Moto 107" kit. I need to exchange my jugs but that's not a big deal they do a core exchange so hopefully I can get mine off within a day or so and send mine in. It comes with TW555s, gaskets, lifters and pushrods. I figured if I could do car work and help my roommate swap out his 350 sbc out of his boat then I should be able to do a big bore kit on my bike. I just don't want to scratch or gouge anything on accident and trash the motor. I figure for the price of cams and a 107" kit doing the install myself and getting the dealer to dyno it I would end up paying around $1500. For their 103" kit it would be $1750 for the bore with no cams or $2700 w/ cams and install.
I still don't get where an extra $275 is going with their bore kit and dyno tune. Separately it should only be $1475... oh well I'll figure something out soon. As of right now I got my rear fender to bolt back on now that its cut and the bracket is chopped a little smaller so it will pull it away from the tire.

What djl was saying was that between the 88" engine and the 96" engine, Harley increased the stroke from 4" to 4 3/8".
So an 88" bored from 3.750" to 3.875" goes from 88" to 95" and a 96" goes to 103".
107" is the max with the stock spigots. After that you have to bore the cases to run bigger cylinders / pistons.
To the OP:
If you're not looking for huge middle and/or top end, why not consider just dropping in a set of Andrews 48H cams? Easy DIY job and cheap. LOTS of low-end grunt.
I started with that thought process but things have "grown" since then.

You are correct, bore is increased to get more cubes. Up to a point.

That's what I'm mainly trying to figure out. If I can get away with just cams and a good tune I would love to stick with that. That way I can get my moneys worth out of stock parts and then bore it out later. My original plan was a hook up on some cams and try ported heads and possibly manual pressure release valves. I know I can install cams on my own that wont be an issue. I might talk to the dealership and see what porting the heads would cost. I would like some mid range power... enough to pull away from most vehicles in traffic when I get to get away from the stupid Jacksonville drivers.

If I had the money and living in Florida I would definitely talk to this guy
http://docsperformancetuning.com/About_Us.html
Or also Veetwin Performance in Orlando who I also think is a sponsor on here.
Doc is very well known in the industry for his tuning capabilities

I'll have to check a couple of places out. I really want to get a hold of my old roommates dad since he is a good dyno tuner and hopefully can get me a great deal on some parts. I'm considering buying TW-555, TW-777 or CR-575 cams and doing the install myself with my roommate.
I finally got my fender cut and lined up pretty well... nice even gap all around so I may toss some money into getting it painted and pinstriped. I started installing my lowering kit but I ran out of time and had to go to work so hopefully tomorrow I can post up a few pics of her 1-1/2" lower with the fender all setup right.
