I have a 02 cr250 husquavarna with fmf platinum pipe pro circuit shorty and Vforce rad valve. Might be nature of the beast this is first non jap bike Ive road but it has no snap to it I like to ride with the front end in the air wide open style but it seems to be very flat from mid to top end I dont know if it has been rejetted or if its stock I live in Ne. I think about 2k above sea level I have looked on every web site I can find to see what recommended jetting I could find but it seems no one has any thing. Any ideas ???? feeling doggy
