I have not read through the entire 50 pages, sorry if this is a repeat.
To remove a centerstand from a bike, you will need to take off the centerstand spring. They are strong springs, and difficult to pull off. To easily remove, set the bike on the centerstand. The spring will be streched. Reach under the bike and insert 5 or 6 coins (nickels quarters , etc) in spaces where the spring has been streched. Then when you push the bike off the centerstand the spring will still be stretched, and should easily unhook from centerstand and frame.
