I've got the bobbins on mine. One still needs to be careful about lifting up when loosening the axle nut as BT mentioned. With a little practice, putting the bike on the rear stand isn't too bad. I learned to take my helmet off first. My chin gaurd partially obscured my view and I had a close call by not having on of the brackets on the right side bobbin correctly. Almost lost the bike on it's right side. That's a big almost, luckily.
