Well I went to jack frost yesterday with my 416. Its running extremely lean.
I got a fcr39mm carb as most of you know. 185 main jet, needle on 4th groove, and air screw is pretty far out.
Now I am thinking to myself a 185 is way too big for my setup. So I think were my problem is, is the air mixture screw.
Now let me get this straight, When the screw is all the way in its at its leanest point and when its all the way out its at its richest point?
Let me know how far out you guys air running your air mixture screws. i never counted the turns I just stopped tunring the screw whent the bike ran the best.
