Brian,
Most of the time vintage machines trade hands without titles. I only have a title for one or two of my machines right now, and I have a lot more than that.
4-strokes are more trail friendly and have better manners when trying to creep along. Also, 2-strokes are very loud and difficult to travel slowly with.
Shipping a 6-wheeler is easy. I use u-ship and always buy a machines based on an estimated $0.50/mile to get it shipped to me. I don't think it's ever came to that much, but it gets really close sometimes. Also, the shippers will start out way high on their quotes usually. Don't be afraid to wait it out or ask to have it shipped for your price rather than theirs.
Good luck,
Drew
