nahh. i dont imagine. cause the vapor in your tank would have to travel through your gas. through the carb. through your reeds and into your cylinder. then somehow not explode until it gets into your exhaust. i dont think that would do it. ~pat

It is unburnt fuel being ignited by the header.

IDK! The carb is loaded up w/ fuel and more fuel is entering the combustion chamber than can be burnt, it is expelled and reignited by the heat of the pipe. Just an edumukated guess!
