hey there, just picked up a 2001 ttr125 for the kid and am trying to get it all tuned up before I give it to him...nothing like a broken present. I was woundering if someone could help me out with jetting the carb. right now the bike is stock. I am planning on doing the airbox mod, stock exhaust, and we are at about 200-2500 ft above sea level. Any help would be greatly appreciated...what size jets, how many turns out on the fuel screw etc. Hope to hear soon, birthday is quickly approaching!
