It's a misconception that anything that does not match, right from left, in the front end will result in "pulling" or off balance riding.
As much as I hate to beg to differ (having read a few of your posts), I have to beg to differ...one fork being higher than the other, CAN and WILL affect pulling or off-balance riding. I have experienced it first-hand, on a Honda CB750F, on which we inadvertently placed one fork tube higher in the tree. Handling went from great, to zip, until rectified. As in the quote below, it causes an offset, between front and rear wheel, which affects handling:
WHEEL ALIGNMENT: (1): In the most basic form it means that the front and rear wheel are in-line. That is, they point in the same direction and are not offset from each other. (2): A more constraining definition of the term also requires that both wheels are in the same plane. That is, one wheel is not vertically tilted with respect to the other. On a motorcycle that is not properly set up or has a bent frame, forks or swingarm (1) can be true without (2) being the case.
