Hi guys ! I've been asking a lot of questions lately but my '06 Busa is still new to me. I decided to buy these Yoshimura slip-ons and I finally did. The bike is stock with the exeption of the slip-ons.Is it really necessary to buy a Power Commander? Some guys say that there is no ECU adjustment required as long as I don't have a full exhaust system. I know about Power Commander since I had it on some other bikes. My main concern is for the bike to run ok if I don't do anything else to it. What do you guys think? Can I just ride it like this? Is it gonna hurt anything? I am just trying to avoid any problems.
