To add a little, using other people's jetting is a rough guide at best. Each bike is different, locations (e.g. altitudes) are even more different. It's a bit short sighted to spend all the money and effort on pipes and open airbox and not spend the $50 - $100 to get an experienced tuner to setup and dyno your bike at your location.

Please be aware that these are my uninformed deductions are only ment as a guide.
On another more general topic, why so much grief on rehashing a topic?
Just because it may have been discussed in the past by others why not welcome newcomers to air their 2 cents worth, it,s nearly censorship.
Often doing a search and reading the past posts just raises more questions.
If you don,t like what is being discussed, go for a ride, it,s not compulsary to participate.
If there is something on tv that you have seen before you can ,change channels, turn off the tv, or leave the room. Steve
