Idea for pulling dents from header.

The difference between a car panel and motorcycle tanks is significant. At least for KZ's, my Yamaha tank is tin foil next to my KZ's. I would try it on junk header first of comparable wall thickness. I saw other members here mention using large steel ball bearings in varying sizes to take out dings. I would they would start off with smaller diameter first and then gradually move up. But I have never seen or read how they use these bearings. Should try finding out.

Edit: Opps, I guess I type and post too slow LOL. Thanks Patton, I have always wondered how they use them.

When water freezes, it expands about 10%, so this fix relies on this physical property. Fill the dented pipe with water. Wrap the dented area with a rag for insulation. Leave the ends uninsulated. Stick the pipe in the freezer with the dent centered as the lowest point. The ends will freeze and create a plug on each side, and as the water freezes it will build pressure high enough to push the dent out. We use freeze seals in the nuclear industry and depending on the length of the seal, can hold upwards of 3000 psi.

You will want to thaw from the ends first as to prevent creating a vacuum if the middle were to thaw first.

I have done this procedure on a Superhawk header and it worked great. The only sign there was ever any damage was the scratch that was left from the damage.
