I have a 2013 rmz 250 with a PIM 2 and a Dr. D full exhaust (also have a Yosh RS4 full system) and a no toil hi flo air filter and cage, rest of bike is stock. I leaned the yosh full system map by one across the board and it seemed to run a little better with the Dr. D system. This is just a seat of the pants dyno. The Dr. D system makes better mid and top power IMO. I am using the rich OEM coupler. So my questions are ; Has anyone played with this set up yet? What were your results ? Does anyone have a map that they feel works better at sea level for either system ?
