Sounds much like my 85 Virago, built in late 84 as an 85 model and without ever being titled or registered I nearly sought it's title as an 84. Fortunately research showed there was no 84 Virago 700 and I made the right call after deciphering the VIN number. DMV would have easily let me title it as an 84. A data loss at DMV, a lost title, a new title could be created with an error easily; the important issue is there is a clean title in hand without lien. The mystery may never be solved but it still rides, that's what is important.
