I guess i'm dense. As long as the crankshaft is turning, isn't a spark still being produced? So if some amount of fuel is still being sucked into the engine on downshift, why doesn't it just combust within the cylinders, instead of being passed into the pipes?
I had already plugged the hoses coming into the reed valves, and it was still popping. Tonight, i turned the screws out to 2.5 turns, and the popping on decel stopped. It's now idling around 1100 rpms, definitely smoother, and just a bit higher than just under 1000 before I turned them.
There's obviously still a part of the combustion process that I am just not understanding. I'd kind of like to understand what's going on in there, even though it's working fine.
