heat with a propane torch till it becomes slightly red throw a cup of cold water on it and the dent will some times pop right out and some times it takes a couple of tries but eventualy the dent will come out.
I've done it on cars and bikes it does work.
maybe it's just me, and i'm no expert, but i thought that by heating up any tempered metal (and a few bikes are tempered, I personally have an older one that is) you are weakening the metal, amking it somewhat hazardous.
