On a GS, I've never had much luck catching the edge of the lower race, even with a "bent chisel" sort of tool or any of the commercial "bearing puller" tools (none of these contraptions I've tried actually, you know, frickin' work). I just go straight for the Dremel now on steel frames. On modern bikes with aluminum frames, there's usually a slot cast into the bearing seat area that makes this easy.
To install, I use a set of tapered aluminum bearing and seal drivers from Harbor Freight. The aluminum discs can't damage the hardened steel of the races:

These things are ridiculously handy. Grab a 20% off coupon from the nearest mailbox or magazine and get you a set.
To get the races started, use two of the discs with a length of threaded rod and some nuts and washers. You probably won't be able to draw them into place all the way like this, but you can get them started straight and seat them by hammering.
I also have a large copper hammer I inherited that is just the ticket for bashing bearing races into place without damage. Not a common item in most garages.
Looks like a good thing to have.
