    Replacement tank for an '83 Suzuki GR650

    The GR650 comes with a tank that has a capacity of about 3 gallons. I'd like to replace it with something bigger. Anybody have ideas what other tank from other bikes would fit? Thanks!

    FYI: I created an album that has photos of what I did to put a bigger tank on my GR650. Hopefully this links works...

      Yep, the link works.

      Do you have anything else supporting the weight of the front of the tank? I would think over time, that rubber might give out and drop the front end.

      Looks good though! And thanks for documenting it!

        Good point. I'll check and maybe put a bumper near the front underside of the tank to sit on the frame. Thanks!

          Results look good, though; I had some reservations about the extended front bumpers too, but I see you've addressed that with the internal bumper that will sit on the frame tube. That will take a lot of the weight, and a full 22L tank is a heavy b'strd.
