    Wobbles feel as bad as they are not good... When you changed out your front end, did you keep an eye on the trail? Have you checked the fall-away? Steering head tight enough? Tire pressure good? Tire balanced?

    I ain't a good wrench, so these are just the basics, but it's usually the basics that cause the biggest problems...

    When you changed the front end out, did it come with a rake (ie: 3, 5, 7 degree, etc.) to the trees? if there was a rake and you didn't compensate for the trail as well, this could be the source of the problem. High speed wobbles are the source of "widow-makers". Get it checked out by a reputable builder / shop, and keep the speed at a minimum until then. Also may want to check out the spacers on the front axle. Make sure they're right for the wheel you're running.
