Disclaimer:
I don't know what the crap I'm talking about, but am gonna ramble on anyway. What is said is in NO WAY backed up by and scientific experimentation with double blind sampling or taste testing. Just thinking out loud and talking out my rear end. Feel free to jump in my poop and chastise me. I won't care anyway.
I don't know how relevent this all really is. Math can be manipulated to get pretty much any result they desire to prove they are right. So here's my math:
More air in + More gas in + good exhaust pipes = faster bike.
Granted our beloved(?) CVK carbs work via vacuum pressure and all that scientific nonsense so impeeding the airflow will cause a loss of power.
I know for a fact though, dyno prints to prove it, that my torque line flattened out and increased by removing airbox, upping main jets and adding aftermarket pipes. This is comparing my previous setup with Mikuni carbs and K&N filters, no airbox. I know have CVKs back on, and still have K&Ns, no airbox. As I tweak more and more, the torque curve keeps rising and getting flatter with each minor tweak and the HP keeps rising as well proportionally.
My assumptions are based soley by the seat of my pants, my gas consumption, my grin factor and the pesky little machine called a dynomometer. Actually the same results on 2 totally different dynos in case anyone cares.
Fire away, I can take it.
