My opin' on the low end bog is it's all about the CV type carb. "Roll" on the throttle and it's all good. It's no "pumper."
Went up from a #35 pilot. Did too many mods at the same time so....... The bike really is alive now though. Some trial and error I'm afraid.

+1. The larger pilot jet helps a bit with the transition at the low end, depending upon your needle clip position (more noticable at increased needle hight). We had a forum member that was using the larger pilot jet with a #140 DJ main and BG race core, no AB lid, K&N filter. He said he loved the top-end pull with that large main.
