Nice 490 j.d....I do believe someone changed the color scheme to blue, but it was never yellow and black. Yamaha had abandoned this by 1984, and went to white fenders, with a red seat etc...but I do agree the old yellow and black looked cool. In fact they are making some retro graphic and fender kits for the new yamahas that have the old late 70's and early 80's bumblebee thing going on lol. I bet since that 490 has a four speed and is geared so high in first, you are going to have to end up gearing it down a tooth on the front sprocket for riding around west tn. LOL shoudln't cost too much to do and try and see if you like it
