I think the AI removal probably does make the engine run slightly better since the AI isn't robbing any vacuum from the left intake. Doubt it is enough to register even on a dyno and definately won't feel a change. The Freak does leave the bike looking stock bur helps improve the way the engine breathes. Only way to really take advantage of that is to open up the exhaust too since the extra air/fuel mix needs room to escape after it is burned. That will increase performance. Have to rejet for sure.

I learned all I need to know about life by killing smart people and eating their brains.
