    I had some dents that I was able to pop out by sticking a tire iron in some of the various openings(gas ,petcock) and putting pressure on the dent from the inside. Others I used bondo.
    Also had limited success with those suction cups.
    That's three ways.

      Degree of success depends upon the severity of the dent. If there aren't any creases you should have pretty good luck. I've used a suction cup with major success and also one of those devices that involves dripping hotmelt adhesive on the surface, bonding a plunger of sorts to it and then pulling it out. If you use one of these type devices though be forewarned that they can also pull any decals off. Don't ask me how I know.

      Common sense has become so uncommon that I consider it a super power.

          Dent repair is easy…take the bike to the desert and drop a firecracker in the tank.

            Wow! Hey Ed, how big of a firecracker will I need for my tank? Or should I just leave the gas in it?

                Wow Cliff !!

                As much as I'm happy that you're on the mend, I really hate to see Jessie like that !!

                Have you come up with a list of the damage and the parts she will need ?

                I have a couple much smaller dents in my tank. I had a friend tell me to use marine epoxy. I haven't researched it yet, but it's supossed to be similiar to bondo to work with and won't ever shrink.

                  That's far bejond my limited abity to deal with. If you can't find a good used tank, perhaps there's one out there that you can salvage the right side. I've grafted a Hyabusa filler cap on the 1100 and can tell you that the GS tanks are built with thicker sheet than the new bikes, so it makes them easier to weld, or braze depending on your preference.

                    Even on a creased dent, a body shop may be able to pull it out with a stud gun - they weld metal stud to the cavity, strap the tank down, then pull on the studs with a slide hammer. Sound easier than I think it is. (Mine was apparently about three hours of heavy labour.) Then standard body filler and finishing.

                    If you want that solution, you'll need to find a willing shop and clean the tank out well beforehand.

                      I had about a 3" dent in my tank, and I had it proffessionally removed. My bodyshop used a special "spoon" specifically made for motorcycle tanks. The spoon, and some gentil heat, and he got 90% of the dent out. I was VERY impressed!

                      My advice is if you are asking on the internet "how" to remove a dent, just leave the dent alone, cause i'm betting you will make it far worse than it already is....

                        Here is what mine looks like and no one I have talked to holds any hope of repair. I have acquired another tank which is Black and has a couple of dime size dents in it. Since mine doesn't leak and functions fine, I am riding it as is until funds to repair and paint the other one become available. Besides, a tank bag camos the damage pretty well.

                        Life is a balancing act, enjoy every day, "later" will come sooner than you think. Denying yourself joy now betting you will have health and money to enjoy life later is a bad bet.

                          Hrmmm Scott, bang one just like that into the other side, and from that angle it ALMOST looks like a Bandit tank

                              Believe it or not, you are the second person to suggest that!
