Don't know if I'm the only one, but you don't need any extra fuel pipes/spark-plugs to accomplish flame-outs. I do it every day on my bike just to scare people-
1. On the over-run, when slowing down, when the engine rpm is around 4-5k, flick off the kill-switch on the handle-bar for a couple of seconds, then flick it back on---lots of unburnt fuel dumps into the exhaust and ignites, giving a 'shotgun' sound, plus a flame about 12 inches out of the pipe.
I'm sure this isn't very good for the engine, but its fun watchin people duck down!
Anyone else do this at all?
