I went and looked at a yfz 450 today, it ran out fine and all. Needed minor work, but i noticed the vin was scratched and only had the first 3. The bike has the Florida DMV offroad sticker, which you have to have the vin to get one. He doesnt have title either. So my question is, he's got the sticker, but no vin, should i get it and use acid to recover the vin, or let it go?
