Well since I got the bike there was always a little bit sticking up out of the top of the tree maybe 1/2 inch or so.....yesterday I saw in the manual that it says that it should be flush so I moved the forks down so as to be flush and the only thing I really noticed is now I need to adjust my bars and/or seat back a bit to compensate......as far as the way the bike handles I don't feel any real difference. Of course we're only talking 1/2 - 3/4 inch difference.
