    Wasn't that because the frame became an oval?

    Loose steering stem, hard braking, stoppies.

    Ok guess next question is there a fix? Is this an issue?

    A hard crash will do that too. Been there, done that.

    Yeah, and hard impact to the front end. I've heard of slivers of beer can being used to fill the gap.

    Shim stock. .002 and move up from there.

    It was common on 88/89 models, its why the factory braced the 90 model.
