Up for sale is a gas tank removed from a Yamaha XS850, year unknown but I believe that it will fit 78-81 models. There is surface corrosion all over the tank and 2 spots of bondo but there are no cracks or dents other than a slight bend on the front as shown in the close up. It is in good solid condition and ready to restore. I do not have a key to the cap so I was not able to check the inside of the tank, but it is likely that the inside of the tank will need to be flushed or sealed due to rust. Thanks for looking!
