Greetings all, I have a dent about the size of the palm of a hand, just below the gas cap, looks like a panic flight from a green rider. No creases, what is the best way to bring this back. My sr only has 2652 orig miles, she is a gem... ![]() [/img] |

Go and see a good paint shop...ask around...they can probably push it back out carefully if it can be accessed and there are no sharp edges to it. SR  |

If your VERY careful, you can pressurize the tank with compressed air and push it back out. I have done this a few times but you have to be careful. To much pressure and you can split a seam real easy.

To much pressure and you can split a seam real easy. To the above, I would add that you should take steps to prevent the air pressure from spreading the tank halves further apart (which might make splitting the seams even easier). When there's a seam protruding below the bottom of the two halves, I've those put those seams in a large vise with just a little tension to prevent outward movement of the halves. If that isn't possible, I'd try using a couple of ratcheting tie downs around the mid-section of the tank to accomplish the same effect. |

If you decide to repair it yourself, you'll need a strong bar with a curve on the end so that you can insert it through the filler hole and reach the dent.
Wrap the working end with a bit of cloth and tape to achieve a small ball.
When pushing the dent upward, DON'T push on the center of the dent - start at the outer edges with gentle pressure and work your way around the perimeter. Think of watching a movie in reverse. You want to start your efforts on the last of the damage and work your way back to its beginning. Be careful not to apply too much force in any one particular area. Very often when you relieve the stresses at the outer edges of the dent, the rest will "pop" back to its original shape. If the outer edges of the dent have no sharp creases you may not have to repaint. Good luck!

Depending on the shape, position and size of the dent I have used a simple rubber sink plunger to pull out a dent, I promise you it does work!

Fill your tank about 3/4 full with water and seal the filler hole with a large rubber stopper. In your case, turn the tank upside to position the dent at the bottom and to keep the water clear of the seams. Put the tank in the freezer in this position. When the water freezes it will usually "pop" the dent right out. After the dent has disappeared, let the ice melt and drain the water. Dry the inside of the tank with compressed air. Fill it with petrol and you're done. We do this to dented 2-stroke exhaust expansion chambers all the time. The wonder of physics at work.
