GT Chucker XS.2 headset problems

[atugwell82]

hi i have a GT Chucker XS.2 but when i tighten up the head set the steering is really stiff, so i loosen it so it turns easier but then there is a lot of wobble in the headset. i cant seam to win. i have changed bearings a few times but am still having the same problem. i dont understand it as i have a Schwinn bike and i can tighten up the head set really tight and the steering is still fine. if any1 knows how i can sort this problem out please reply asap thanx.
