So I had a shop give me keihin jets. 170 main, 55 pilot. Needle on second clip. 500 above sea level. 421 assassin, 38mm pwk carbs, cool head, cpi in frame, shearers. Anyways, I went riding and was lean as hell. Moved the needle to 4th clip and it helped but not much. My kx125 beat me in a race. Wtf? Sent from my SM-N920V using Tapatalk
