I'm confused ???
1st you say you are gonna add a hi-flow air filter kit...
Now you say you are NOT gonna change it ???
If Ur leaving it how it is, & spark plugs read fine, runs fine..
Then just ride it..

carb
Get a mirror, look at the bottom of the carb to see if the plug covering the idle mix screw has been drilled out, or if a new finger turn mix screw has been installed. If it has, then someone may have rejetted the carb or at least been in it before. If the plug is still there, then most likely it is still factory.
Plugs ok, runs ok, MPG is good? Then don't try to fix something that ain't broke.
If you go with new AC, then put in new plugs and check them to see if you have leaned out?
Lots of info on here about plug reading.

Yes because i thought about it, every action has a reaction, and if its fine why add a "higher flow" air cleaner, i wont feel the differentce in power at all, and it will make my bike lean why do it.....

Accoring to this..
http://www.thunderheader.net/tech.php
according to the tech sheet at thunderheader it seems the way its designed so you may not need to rejet, if your bike is stock.... fyi for people......

sounds like you found the 'idle-mix' screw location..
Yep if un-capped, it's at least had the idle-mix re-adjusted..
A motor is like an air pump, the more it can inhale & exhale, the more efficient it runs.
That picture of your bike ? shows an S&S air cover, what air filter is in it ??

ok bike is not fine... i changed plugs and it rides way different( i think the plugs where fouled for a while and not giving full spark)..... now it bogs when i floor it and no smoke the plugs are rainbow colored i dont think they has enough time to turn white..... so could someone recommend jet sizes for this set up(cv carb) or can i just turn the screw out and how far is too mch to turn
