LOL, our bikes are sure jetted differently! Did you do the accelerator pump mod with th o-ring? That does a lot for throttle response.
Heh, I replaced the 06 head and valves with an 07 R head, stage 1 hotcam and stainless steel valves. With the smaller airbox and more restrictive exhaust, a 162 main is where it's happy.
Did you go up in pilot jet size too?
