Hey I’m really in need of some help. I have the 1982 XS400 Seca and I want to put a tank like the same Shape as as SR125 on it. I have read so many forums but I cannot find out what other tanks would be capatible with the frame. I’m so stuck could you please email me if you know anything or anyone who can help. I’m trying to do this bike up and I’m really stuck.
