Bert, taking the motor off a moby is so simple. it drops weight so you can spin around the frame.
I used the 3 step process that they sell to clean out gas tanks and I hung my moby up in my garage from the garage door tracks and through the opening for the tool compartment (which I removed). It allowed me to move and spin it around without having to fight the weight of it. It really helped out for getting to the hard to reach areas (ie the very top of the tank next to the handlebars).
I'll see about showing up to GR on monday but I have a feeling I am going to be in the darkroom all day.
