here is my most recent run after 904 with port/polished head and +1mm oversize valves. I know Frank has the same setup I do but with different carbs. Matt (ditch_dr) did my port and polish, he has a thread in the vendors listing, good work and a good price. If you contact Bill Gately at bonneville performance, he will answer all your questions. I dont know if you will find a performance increase for every step like you want, but the dyno table thread should give you an idea. There are a lot of variables on the graphs (pipes, jetting, elevation, machine, etc.). I am very happy with mine, the torque is great riding two up now, the lag is gone.

Always remember to be yourself. Unless you suck. Then pretend to be someone else.
