GULG has a listing on the forums that tells you how to do an installation using a long bar and socket (32mm).

"stand on the right side of the bike, bike on the sidestand, in gear and stand on the brake pedal, reach over the bike, and pull on the strong arm (that is connected via a socket to the sprocket nut), it works perfectly. If you are worried about your back, rest your chest on the bike and use your shoulders/arms."

Now this was all well and good until the moment that decided to really pull up hard, forgot that the right foot was cramped up for a reason (covering the rear brake), the moment I moved my right leg, that let the bike roll forward off the side stand and almost toppled over.

Luckly nobody around to laugh.

It has inspired me to write a ditty to the pentamic meter of "the 100 green bottle" song.
