Just recently improved on a an enviable bike. Mine is a 2005 Pitbull with 15.5K on it. It now has new lifters, seals, S&S rockers and rocker boxes, a shiny new Baker belt drive, and a 600 Cam. This thing screams now! For all of the 05' owners with TP rocker boxes: GET THE GEOMETRY CORRECT! Can't emphasize this enough. Love it all over again.
