    WOW! I wouldn't have thought it would work THAT well. I wonder if the titanium helped?

    He said he didn't have to cap it or fill it up to the max. I thought it would just expand at the path of least resistance.

    Can't wait to try it.

    Nice tip, I will try that for the right side head pipe on the airhead project.

    I saw this attempted one time on a KTM expansion chamber. When it came out of the freezer it was so bent out of shape that it would not fit back on the bike and had to be replaced with a new pipe. I also have a friend who tried the same method with a gas tank dent and ruined his gas tank.

    We all know that water expands as it freezes and doesn't it expand uniformly? If so then how does the expanding water push the dent out of the pipe and not stretch/straighten the rest of the pipe?

    We used to do this all the time to fix our bashed-in vulnerable 2 stroke pipes.

    There are limitations though as we found out with a KX125 pipe with a near flattened belly. On the third round of refilling and refreezing to try and expand to near stock spec the welded seam split leaving a 9 inch gash.
    oops.
