No WAY! I've got a '79/'80 Indian in SF!!! My first moped. Fixed it up myself and had it running until something went snap rattlerattlerattle a few weeks ago. I'll be opening it up, anlong with a spare engine I picked up, and you're welcome to come by and work on yours too.
Here's some stuff to help you along. Read and research a TON. I knew NOTHING of mechanicalness until this project, but the info is here, and the feeling of getting it to run well is....yeah. You do have to be willing to make some mistakes, but that's what the parts link is for.
Check out the Indian Goodies thread thread for crazy insane amounts of info.
The best resource I found for Indian parts was The Parts Store
There's also a guy named Bob who was way helpful and apparently has tons of parts, but he seems to have other stuff on his plate, and fast shipping isn't.
