I start by assuming the deceleration popping is just the effect of the AIS (Air Injection System) on the gen2 KLRs. Mine does it when I close the throttle and decelerate in gear with the clutch engaged and keeping the engine turning at speed. A little fresh air is injected into the exhaust manifold to help burn any raw gas in the exhaust.

I think the best way to adjust the idle mixture screw is to turn down the idle speed stop to the lowest rpm it will run at the turn the mixture screw in and out to the highest idle point. Then lower the idle speed stop again and readjust the mixture screw. Do this a couple of times and then set the idle speed stop back to normal (1,100 to 1,300).

Three quick comments:
I had nasty popping on decel, and it was almost time for a valve adjustment. When I adjusted the valves, most of the popping stopped.
I then removed the AIS using Eagle Mike's kit. The rest of the popping stopped.
I read somewhere (maybe on Watt-man's site) that there is a stronger-than-expected relationship between idle speed and engine temp. His advice was the same as the advice you got from GoMotor - keep idle low.

Fast, good, cheap - choose two.
