Looked into that. Some parts are close, but not close enough.
The ducati motor is similar to an early Morini 3M. But the Ducati cylinder has the intake cast into it, and the push me pull me shifting is totally different, as well as the rear brake.
Gotta hook up cables and a chain to figure it all out.
I mentioned it earlier, pedal backwards, some how it pulls the cable for the rear drum. Weird.
