06 crf 250r with mods jetting help by Jbird437 » Tue Jan 06, 2015 6:08 pm
I have an 06 250r that has had the head service with a 13:5.1 wiseco piston installed. It also has white bros full exhaust. I live in Missouri which is 800-1000ft above sea level. What is the best jetting setup for this bike?
