Fuel screw? WR400 99 Which way is lean and which way is rich? I messed with it and now have a little off idle stumble. Please don't just direct me to another thread I have a lot of gettin' ready for a race. So please give me the quick low down. Also I took the plug out and found that it was 1 heat range colder CR9e vs CR8E which is stock I am planning to mx this weekend any input and I'll kiss ya'll's a$$ on main street at high noon! THANX FELLAS!
