I struggled with my stand for a while and I got so tired of calling to the girlfriend to help me pull it on the centerstand....kind of embarrasing in public you know :-)
I finallly figured the trick.
Step on the very bottom (back) of the stand. The part that touches the ground. If you do that, get a good grip on the crash bars and get your weight right the bike should roll up on the stand fairly easily.

Since my newly acquired Ambassador is a first 'loopframe' for me I just would like to ask one question? How in the heck can you put it on the centerstand? Is there a trick that is learned?
