I did the air box mod on my 07 and I am wondering why I waited so long to do it in the first place. On my bike the danger of water in the air box is no greater with the mod and I was able to feel the power increase on the first ride after the mod.
My front lifted up easier after the mod when I rolled it out in 1st.
I put on DanMoto slip on exhaust, it made me run rich, I did the air box mod, it leaned me back out. I am saving for a PC III but it is running great now in the meantime.
Think of it this way....a replacement stock air box is like $35....do the mod and if you want to go back just buy the stocker. I have a feeling you won't go back.
