Maybe hes motivated to sell. He says he didn't build it so its entirely possible he just got he year screwed up. I thought I had a 2003 Aprilia for 5 years until i sold it and saw on the title it said 2001! lol. If he drops it any further I will go buy it and find somewhere to squirrel it away.
81 frame but 82 or newer motor unless newer top end fits 81 motors . I dont think they do though .
Edit That defiantly looks like a newer motor . Look at the covers . Newer style clutch cover . Newer carbs .Its not an 81 thats for sure . .Being a track bike and not much standard guess it doesnt really matter. Mine has a newer motor too .
