[QUOTE="Firfitr113, post: 211601, member: 4532"] Hey guys I just bought a 2017yz250x. I live in Tucson az and elevation is about 2500 ft. Jet setting is 178,50 and in 2nd position. I keep fouling plugs. I just started running 40:1 for fuel hoping this will clear up my problems. Does my jetting sound too rich? It is all stock settings. I'm trying to learn and understand all this jetting stuff. Rob [/QUOTE]
