I am always mounting front racks on the strangest friggin bikes imaginable, the kids that come to our touring company bring some screwed up rigs....

And I always mount em, see how far off they are, grab the front hoop, and bend. Go slow, with even and steady pressure. They wont break unless you try to bend them past the wheel or something.

Most often this has to do with the fact that there is no jig to weld on the eyelets for rack mounting, so they are not perfectly square. Unless you ride an Indy Fab, Bruce Gordon, or Rivendell, then you will most likely have to bend a bit. Even on my LHT I had to bend.
