you should look on the fram of the bike right in front of the gas tand on the side and it should tell u. 1977 250 YZ250D 1W3-000101 6520 NOTE: This Is The First Year Of The Plastic Tank, Used On All Bikes Except The YZ80, YZ100. It Was Also A Completely Different Frame/Monoshock/Engine Design For The 125/250/400 Models. Bob (Hurricane) Hannah Raced An Almost Completely Stock YZ250D In His Sucessful 1977 Season. From this very helpful YZ identification web site. Hope this helps http://craigmac215.tripod.com/yzmodels.htm

The serial number plate is on the front of the frame below the handlebars, behind the headlight. For 16-digit serial numbers, go to the Yamaha web site. For serial numbers less than 16 digits, take the number to a Yamaha dealer and ask for a search from Yamaha Japan.
