On my 2000k mile run recently, I noticed some intermittent hesitation/decel while at steady throttle. Pitch of the engine doesn't change. Only seems to happen after riding a bit. Couple days ago, heard some popping on decel. Not crazy, but there. Before the popping, I assumed it was a fuel delivery issue and changed stock petcock to EM. Tank vent checked and new fuel line isn't kinked. So diaphragm first?

Guessing I'm after a carb rebuild with diaphragm? Have seriously considered a KLX kit, but I'm not power hungry on this bike. I dig the range 45-50 mpg gets me.
Any aftermarket muffler can not Muffle the trailing throttle after-fire as well as the oem muffler will.

A loose exhaust header pipe or damaged header pipe gasket or crack in the header pipe will cause more & louder after-fire / popping.

A rotted/damaged/sticking idle air cut-off diaphragm will cause more & louder after-fire / popping.

The 22 cent mid-range needle shim mod or the KLX mid-range needle may alleviate your mid-range steady throttle intermittent hesitation.
