.45 HR CMB running 40% with 18% oil...LSN was at 1.5 and it starts and idles very well. I started the remote HSN at 3 turns out, and I think that may have been pretty lean...still working with the engine and trying to find a good tune, but I would start at 4 turns out if I was to start over. Realize that your HSN setting will vary with what pipe you are using...different pipes will give you different back pressure, resulting in different needle setting.Running 30% 22% oilNeed starting needle settings for NRossi 21
