I have a Huffy. I didn't pay close attention to the headset adjustment. It loosened after several years. It was too late to tighten the bearings, because the races that are pressed into the frame became loose in the frame. I replaced the races/bearings and fork (the threads on the fork became mangled due to headset looseness). Now after several weeks, the races are loose in the frame again. I removed the races from the frame and inserted piece of sheet aluminum around the race and hammered the races back into the frame. The races are now tightly pressed into the frame, but I wonder how long this "fix" will work.
