In the August 2003 issue of motocross action there is a really good guide to jetting, but if my digi cam was working i would take some pics for you.



and btw, there is no air screw on 4 strokes, its called a fuel screw

I still havent done it yet havent had the time. I had a quick go around the local BMX track and found myself coming short on loads of jumps that I normally clear because it was spultering on full chat on the take off :( So I really need to sort it out.



Its just I dont want to make is worse.
