Can you make a square pin the same size as your drive cables? If so, you could check it into a drill and drive both speedo and tach (slowly) to see what each component does.

Great work on the bike so far. I just gotta say this, though, I hate the headlight on these bikes. I've seen them through the years and it is always the first thing that catches my eye. To each his own but if it was me, it might me the first thing I would change.
