I just traded a 91 Chevy Blazer that I got in a trade for my 97 Banshee. Well the guy says it's a 2003 Craptor, but it looks pretty worn, so I'm guessing that it may be a little older. So could someone give me the chart for the years of Yamahas and what letter or number it would be. I think you go by the 10th or 13th number, I forget. Anyways, any quick response would be appreciated.
