cleaning carbon

[ESR250R]

i was wondering how you guys clean carbon outta your pipes. i have a esr trx5 pipe that has a bit of carbon buildup on it, i took this thing apart to do some cleaning and wanted to get this out.

feed a piece of steel wire through the pipe, hook a washer or bolt to the wire to hold it in the pipe, on the small end, then hook the other end of the wire to a drill. wear some glasses:cool:

Try some spray oven cleaner and let it sit for a while before washing out.

break cleaner a few smallish rocks or marbles, shake, rinse, repeate.
