you can do the obvios and just buy the mgp fork, but if you dotn want to spend money and wait for shipping you can find someone with an old bmx threadless unsealed headset, there is a piece of it that center's the fork its like a ring with a slit in it and is a cone shape, if you place this into your headset instead of the bottom lock nut with the bearing holder thing, and use enoguh spaceres, it will stop that problem you'v had, and then put on onyl the top locknut and it will solve your problem. also if your smart enough you can ghetto rig a crown race to be placed upside down on the top instead of a cone ceterer thing, and still do the spacers thing if you cant find someone with an old headset.
