    gas tank switch

    Hi all. I`m new to this forum but have a question that I hope you gents and girls can answer. I have a 1981 GS 1000L were I want to replace the fuel tank with a tank from GS 850G or 1000G. Are there any specific problems doing that or are there some other gas tanks that would be a better choise?

    L tanks have different mounting points, so a G tank mounting will require some welding

    1981 GS 850 (anyone want a project?)

      Also note that even though the side cover only says “GS1000L”, it’s actually a “GS1000GL”.

      May not sound like much of of a problem, but that G indicates that it is driven by a shaft, rather than a chain, which is a major difference.

      Besides the difference in mounting points at the front, unless you change the entire fork assembly, the forks will dent the front of the G tank.

        Thank you for that. What about the petcock and all that? Does that fit between 1000GL and the 1000G tank?

            Unfortunately, they are not the same. The petcock on the '80 was fortunately only used for one year. The bolt spacing is not the same.
