Heres my setup: ZA50, polini, custom 18mm intake, 18 dellorto, 6P, 18x36 gearing.
I started out with a simonini, then moved to the 6p on this bike and it blasts (GPSd at 55), takes off alright, and mid range is ok. Is this just the nature of the pipe? Last night I moved my gearing to 16x36 and I now hit my powerband sooner (around 35 instead of 40) but Im sure I lost some top end. Keep in mind Im in Chicago and most of the blasting is from light to light. I have little response in the low/mid once it shifts. Should I scrap the top end pipe and go with a pipe that has a lower powerband like a Boss or Estoril? What do you guys think?
