Well first I do alot of wheelies, jump train trax, and lots of stopies and it makes me wonder since we boyh have the same problem...[smirk]
As far as the job changing the bearings the hardest part will be suspending the bike so you can remove the forks, but the bearings them selves should be fairly simple... bearing pullers work ok, bu I have found in my line of work that a brass punch and some patients works very well for removal of bearings that are seated on the outer race. Installing the bearings can be done using a nylon, or dead blow hammer to start and then switching to a socket that matches the diameter of the outer race of the bearing, be sure that the socket does not hit the seal portion of the bearing or you will be doing this twice... SKF does make a special tool for this, but they can be very expensive. One other option is detailed in the service PDF using threaded rod, nuts and plates to "pinch" the bearings into the steering head simoteanously... I dont like this method, because it doesnot allow you to see that the bearings are not cocked in their seats, and has the potential for a disasterous outcome if you wreck the machined serface of the frame.
