Hello, I recently acquired a Yamaha 250 from my cousin the steering tube is stamped DT1F-153645 11/72 (867). The bike ran a couple of yrs ago I would like to fix it back up, I rode it a long time ago and it was a fun bike. I have a parts supplier in Rush City MN but I can´t find anything about this bike, where do I go? I´m not sure if the fuel tank is supposed to be plastic or not it don´t look write sitting on there and there are no lights of any kind so i´m sure its a dirt bike only not an endoro. any info would help Thank You.
