Do not loosen the bolts at first. I never thought about what is exactly happening. I was just wanting to straighten it out.This will give you the results you are looking for. You are straightening the forks. I have done this before. I might not know what is exactly bent, but the results that are obtained from doing it is all that matters to me. As long as you do not loosen the bolts up first, you can not make things worse, unless you have a problem that is needing to be found out before you would want to ride it. On Puch mopeds, the bolts that were to be loosened up, have a TOP THREADING COUPLING that can strip out, and/or the bolt can strip out, and cause this problem to not be fixed by this method, because those bolts have to stay tight.
