Centerstand, getting it up

All correct. First make sure the feet are both on the ground before you pull back and step down. Best aid is the Wunderlich lifting handle.

Let me guess, you are a 6'5" weightlifter? No way in hell I could do that. Hell, my toes barely touch the ground.

Boxes make it hard, harder, hardest.

Just do like spongebob…

I have a 1" thick piece of plywood, about the size of a deck of cards. I roll the back tire on to it then put it on the center stand. My 1200GS was lowered 1" and it works for me.

Having the bike in neutral or clutch pulled in makes all the difference IMO

Rolling off the center-stand can be more of a problem. The bike should have no steering or vertical tilt and remain that way until off the stand and stopped. Any tilt will be magnified on the bike's movement forward, likely causing it to fall away from you.
