remember that all Gen2's have an AIS system that produces decel pops by design. The stock silencer muffles them better than the aftermarket units.

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.
So I've kept bike stock in the exhaust / carb department, because I enjoy the distance (mileage) the stock setup gets me, but I understand what you're saying. I'll look over the exhaust side.

I'll give the carb an inspection. It's a new symptom and it seems a bit progressive.

Coasting enrichner. I'll have to research.

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?

DPelletier my first thought was tank vacuum as well. The next time it does it, open the cap and see if the problem goes away.

lineman1234 I kinked my/1 of my vacume lines after installing the front crash bars. It ran fine on a 50 mile trip with the wind, and died out 4 times on the way back against the wind.
With help from hear, I found the half bent vac line, and all was well after I unkinked it. BUT, soon after did a pet-cock vac delete.

ILove2Ride2Wheels When you say carb work ... do you mean they rebuilt it? New gaskets? New diaphragm? Cleaned all the jets and passages? It they just adjusted idle and/enrichener?

Did you also pop the gas cap to check for a vacuum? It can happen. If you have a vacuum petcock, that too has a vaccine line and if it is pinched or has a hole the fuel will not flow.
