Okay so I have a 1982 seca 400, the tank is basically trash. It leaks out the cap it has a new leak out the side of the tank. It’s just done. I can’t find a direct replacement any where. What would be a tank I could get from another bike that would fit? Any help would be much appreciated! 

Hi Mors welcome to YOC the best place to start is new members sec, just a quick hi where you’re from in the world, bike experience etc. You’ll get a much better response as it helps other members help you. It is a tricky one as the frame is unusual on your bike but I have seen them with the pre division xj600 tank on. it’s not a straight swop though and obviously you’re gonna loose your side panels. Have a look on xs400.com, plenty on there with mods.

Thank you very much. Yeah I am not seeing a lot on my bike as far as tank swapping. But I will look into that
