ID pipe cleaning (removing carbon)

[croat1]

various tools and tricks are used when trying to remove the carbon from the inside of our pipes.  shown below is the assortment of the tools that I use with the aid of easy off over cleaner (use the name brand stuff and not the generic).  caps to seal off the ends when the oven cleaner is doing its magic (bb's poured in and then lightly shaken).  wire brushes in .010 and .020  wire diameter and various shank mounted brushes.  I was lucky to have worked for a brush making company for 10 years so I did accumulate a lot of deburring/cleaning brushes.  at one time I even made up some tapered brushes (all gone now...worn out).  we have discussed this topic elsewhere....so what are other guys using/doing?

Old MX bike racer once told me that back in the day, they used to plug the one end of their pipes and then dump a big bottle of Coca Cola in it with a handful of marbles, plug the other end, shake it up and let it sit in there for awhile.  Every once in awhile they would shake it up and roll it around, put it down so the mixture was sitting on a new part of the pipe.  Said the marbles knocked stuff loose and the Coke ate everything else.. Dont know if its true or not, never tried it myself, but he swore by it.. I think it would be a good idea to count the marbles when you put them in to make sure you got them all back at the end..

In all these years of 2 strokes being around, looks like someone would have built a tumbler that the pipe could be mounted in, small odd shaped pointy rocks poured in, ends sealed up & tumble them over night to remove the build up inside.
Few years ago, if your pipe was painted, you could take it to an auto engine rebuilding shop & have then dunk it in their hot costic cleaning vat, but you better wash it off quick & get some oil on it fast before the rust set in.
I've seen some of the uglyest dirtyest engine blocks go in & come out brand new gray iron, clean as a babys butt.

I have not tried it yet, but have heard about taking a 5 foot 1/2" round metal stranded wire cable with the end frayed and chuck up the other still tightly wound end in your cordless drill and let it bounce around and clean the pipe.
Painted pipes I just burn the carbon out, but on nickle or chrome pipes it is tough and not much will cut thru thick carbon
