Hello I have a 1983 YZ490 that I payed 300 bucks for. It's in pretty rough shape. It's a 1983 from what I can gather from the serial number. But it's white and also jade the red shock, shock covers, and red Mono cross stickers. From what I know the 83 was yellow but I also know that there was a white euro model out in 83 too. I'm planning on restoring it. Just wondering if anyone else knows more about what color it's really supposed to be and from what I know the frame was supposed to be red for the euro model of this year but its black. Thanks
