At this point, I'm pretty sure I'm going to go with a Kuryakyn Hypercharger airbox. Only one question left about it. How far out beyond the stock airbox does it set? I called Scootworks and they said 2 to 3 inches. That seems like a lot and would probably affect my decision about using it. Talked to someone at Thunder Air and he said it's only about an inch or less for the hypercharger. The Thunder airbox he said is about the same as stock, as to its position. If the Hypercharger is too far out, it's bound to hit your leg and be a little uncomfortable. I've seen some posts in CC saying that shorter people have a little problem with Hypercharger design and if you have forward controls, that also creates a problem. Anyone?
