I made mine a few years to dial in the carburetor and basically check things out before going into the street. Saved a lot of pedalling.
It's just some 2X4s bolted together to form a cross, a rear fork made from some metal strap and two rails to keep the front tire straight. Two eyes to secure tie downs to the handlebars.
The forks holds the rear tire up. I made special rear axle nuts for all my motorbikes to fit into the stand. Very solid set-up when standing up to pedal start.
Folds up neatly for compact storage.
