i believe thats what i was referring to, how the power doesnt really take off until the higher RPMs, mid-range it just as alive... wondering how you can make these "come alive" at lower revs and continue throughout... maybe un-tame it.. do the 650 cams do this?
First off I have to agree with Steve-o because I too think you're over thinking this. It's good to see you're actually reading up on the subject but you're beating yourself up on it. I highly recommend that you get the bike up and running in stock configuration first THEN start playing with it if you're not satisfied. There are plenty of stock 550 owners here who are happy with their bikes just the way they are and you may too.
I can tell you this from my own experience when I first put my 550 together, I too did what you're thinking of doing and started doing mods before I even had the engine running and then couldn't figure out why it wouldn't run worth a s..t and it took me a year to gather up the money and parts to get it back to stock config and it was then that the bike started to run good and from that point on I did 1 mod at a time but even then aside from the 650 cam, dyna ignition, carb jetting and exhaust the bike is pretty much stock.
There are 2 main reasons I installed the 650 cam, 1 is because I can't help messing with stuff and 2 is because my wife rides with me a lot and I wanted a bit more power to deal with our combined weight but even then I didn't mess with the 650 cam until after the bike was running good with the stock 550 cam.
