With the popularity of motorized bikes and the limitations we have with these gawdy kit tanks. I think Custom Gas Tanks deserves it's own forum category. I'm currently building a custom tank. I'm using aluminum and at this point doing a lot of guessing. If you've built your own tank, please offer up your stories and advice. As well I've looked for forums on this here but haven't found any yet. If you've posted, would you please give me the link? I'm particularly clueless on how I'm going to do the gas cap and petcock So please help if you can. I've seen lots of photos of amazing tanks.....just wanna know how you went about it. I'm open to any and all advice. Attaching a current photo. Only about half way there. Those front forks need to be chopped still and a nice Brooks saddle will finish it off nicely.
