I agree , I would find a shop that actually knows how to work on bikes not just bolt oem stuff back where it was in the first place. There is a difference between knowing about the way bikes work and being able to simply bolt things on. I would go with 145 to 155 mains and 42 to 48 pilots (both depending on exactly where you live and what you have on there for exhaust) The gains in performance are worth the effort rather than putting the air box back on.

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