Markus,
Woo!, good information. Thanks again. Unfortunately it's not mine yet. I am considering purchasing it. Since that engine could be original, maybe a full restoration is in order. The only problem is I like to hotrod my stuff and that bike seems to be mostly complete. I don't want to bastardize (improve) something that is reasonably original to start with. I know we are talking about mini bikes and not some low production car, but still, the karma gods may frown upon my means and methods. I need to give this some more thought and come up with a plan if I choose to move forward with this project.
