I'm not sure if this is the right place for this or not but, I put on a V-BAK and I have Sampson Ripsaws w/o baffles. It dyno'd @ 84hp & 95 ft. lbs torque.  The torque is a little flat up to about 2800 rpm but pulls like a freight train after that. My dyno guy said it is due to the short pipes and not having any baffles. I have had several people on here tell me that no baffles will hurt my low end torque before. So I was expecting this a little.  Other than that, do these numbers sound pretty good? Also I have a 260 so I'm sure this didn't help my numbers much. I have done lots of mods while my back has been apart and will be posting pics in the mods section after cleaning it tomorrow

torque seems a little low. I am running about the same setup and getting 104FPT @84HP. But that could be due to weather conditions and other variables. I however do not really have the flat torque curve in the 2000 rpm range though. thats interesting.

Every dyno machine and dyno tuner technician is different, don't read too much into these numbers unless you're comparing to another bike from the same machine/tuner on the same day.  Things really do vary for many reasons.
