Re: Need help
If you've changed wheels then that would rule them out, you could have a look at the discs or drive shafts, is anything loose or damaged, I'm sure you tyre bloke would of checked the surface of the disc to make sure it's dead flat. I had a similar problem on my 300c, in the end it was a very slighty buckle rim, not noticable when you balanced it, only when I had them diamond cut it showed up.
Hope you get it sorted, I know how annoying it is.
