08 duc hyper show up with 600 miles said he wanted a dyno sheet before putting on the DP termi full system. I also have a 600 mile multi I bought last week. The point here is this hyper stayed above 18 A/F tell 5500 rpm then it would come down to a normal reading. It was really goofy we kept checking the dyno thinking it was not picking up the A/F. But ended up making a full pull anyway and yeah Duc has this bike way to lean. I am going to order a 02 manipulator and then put mine on the dyno check, then install 02 manipulator and set it. My bike seems ok to me but after seeing his bike Wow. And I am trying to break mine in easy....................what a crock running at 18 A/F I guess we had better be easy on these bikes................I do have the pollution box of wonder if the intake ports being blocked off help to richen at all.
