Thre is something you have forgotten. I used to try to lift it up by pressing hard on the centerstand, but you have to make sure that BOTH centerstand legs are touching the ground. I generally park the bike on the sidestand. Then, on the left side, left hand on the left grip, right hand on the grab handle, and with the right foot push the centerstand down lightly. Then I tilt the bike to the right (as I'm facing it's left side I should say "I push it", without taking the foot from the centerstand, till I feel that the other centerstand leg is touching the ground. That is the moment that, with the back straight, I lift the bike with the grab handle, push the centerstand down hard and pull the handlebars to the back. Once the bike is on the centerstand I retract the sidestand (if I remember).
To put the bike down I just mount and with a forward motion of the whole body I take it down. If the bike is parked facing a incline it is real hard to take it down for the not-too-tall (as we can't push hard with the feet tips), that whay I put it down from one side, with the sidestand down just in case, and making sure that once the bike is down it won't go further from me but towards me. If I can't hold all its weight the centerstand will keep the shiny side up.
