I have an 03 crf 450, I live in Iowa. This summer a few of us are going to Colorado to ride, Im assuming we will be at about 7000 to 10000. My bike is bone stock runs excellent, can anyone tell me what the stock jetting is, and also tell me what I need for the high altitude???? I dont have a manual, any help would be greatly appreciated.
