I bought a bike several months ago and got a bill of sale ($500 purchase) no title. Owner was a retired fireman and I belive the bike was not stolen. What's the easiest, quickest, cheapest and all around best method to get a title? The tricky part is that I already restored this bike and now it's worth thousands of dollars, if that matters. I did take pictures of all 4 sides before resto. App for duplicate? Abandoned vechile?
