I bought a 77 cb750 that has a Illinois title. The seller and I live in FL. So I took the Illinois title, and the bike to the local dmv. They said I need the seller to be there as well to sign off on the paperwork to getget changed to a FL title in my name. I can't make contact with the seller. I do have a bill of sale that I forgot to bring the first time. If that doesn't work do I have any options, or am I stuck with a bike I can't ride?
