Hello everyone, I was hoping someone would be able to share a little knowledge and point me in the right direction. I have recently acquired a 1982 DT 125 Lc mk1. It is the first and only bike that has come into my possession thus far. It has been stored in a barn for the past ten years and unfortunately the fuel tank has some pretty aggressive pitting in it ( put away with fuel in tank I think). The rest of the bike is in good shape. My predicament is my knowledge or lack there of regarding yamahas. I'm wondering if there is a place where I can see all the compatible tanks for this bike. Does this exist? I've exhausted my google and eBay searches and was not able to find even aftermarket tanks. I'm not looking for a oem resto (as of yet, maybe never) but I am super excited to get it running and learn how to ride. The gentlmen who gave me the bike said it was a great bike to learn on Anyways I apologize for the lengthy post. Any ideas or info or anything would be greatly appreciated good to be here and I look forward to chatting with you. Thanks Greetings from Canada Max Blasto
