I posted this in the Jetting forum, (http://www.thumpertalk.com/forum/showthread.php?t=671195) but have not gotten any replies. I thought maybe I would get better visibility here. I did a search and could not find anything. I have a 2002 CR250R with a FMF Fatty and a Turbine Core II. I ride in between 2500ft and 5000ft elevation. I am looking for someone with this same set up that has found the perfect jetting and carb settings. Thanks in advance. Any help would be much appreciated.
