Anyway I thought it was flame from successful combustion following on behind the unburnt fuel in the exhaust that ignited it?.
I believe its something along those lines ?♂️
What I don't understand is when I was having my bike tuned the guy made sure to get rid of all the pops and bangs because, as you say, its unburnt fuel exploding too far down the exhaust system which in turn means the motor isn't running as efficiently (ie perfect power/torque etc not emissions wise) as it could be. Make sense.. all fuel should be getting burnt in the cylinder and not making it into the exhaust
Yet when I went to BSB last year most of the bikes were popping and farting all over the place?
Now I would have thought those bikes were tuned for the maximum amount of efficient power? I can't imagine their engine management teams would have the engine set up to run anyway but the best it can be?
