so, I have 4 bikes. 2 Baja DB30s, a Baja warrior and a motovox mbx10. the last 2 I got quite some time ago and the last 2 within the last 2 weeks. I never got any papers with them, they were all secondhand. here in Michigan, to get a 'title' so you can get a trail sticker you need an original MCO from the manufacturer or a bill of sale from the prev. owner. of course all of the times I got these, I was so stupid that I never thought to ask for a bill of sale. I have no way to check if they are stolen and I would really not prefer to find out from a cop and get cuffed for having stolen property. 2 of them were from swap meets, one from a yard sale and the other from craigslist. now that I got to thinking about it, I am a little hesitant to even take them anywhere in my truck because im not sure if theyre not stolen. is there anything that I can do or am I screwed?
