Have you done anything to your motor yet? Turbo, NOS, big bore? The reason that I'm asking is my bike was extended that much (8")and I actually lost performance because when you are extended that far...you have got to have some serious power to plant that back tire. I moved mine up to 4-1/2" over and it performs much better.
As far as the look...very nice bike, I like the paint job. I really liked the look of the long stretched bike but it just wasn't performance productive for me.
Nice bike bro!
