I am a new member to this sight but it has been on my favorites list for a while. I have a 2005 kx 250 that I just put a 11 oz. flywheel weight, ordered a gnarly pipe and Fmf 2 silencer and a airfilter kit. Any recomendations on the proper jetting? I am also replacing the 19" rear rim and tire with an 18" set up.
