1. Cracks in the rubber carb mounts. Lets in air at idle and messes up idle. Also makes the bike run lean and hot, and it will take longer to warm up.
2. Carbs out of sync with each other.
3. Valve adjustment out of tolerance, believe it or not. Messes up air flow at low speeds.
Have you drained the float bowls to check for dirt or condensation? There is a drain screw on the bottom.

look for a weak spot in your ignition wiring, such as the hot lead connector to the ignition, Hi-tension leads loose or over tightened and pinched. Plug caps not firmly attached to the plug wires, sparks appearing on the outside of the plugs, etc. Also, a weak spark coil, or a misfiring Hall Effect ignition trigger. Any of the above will be way more noticeable at idle speeds.

If you have a different coil give it a try, or I would be willing to send you my old one. That is an easy item to change before swapping out the entire ignition.
Plus what Vance and JPanyon said ^^^^

Since it's a Ural, first look for the simplest item being the cause of the problem!
Next: Look at whatever was last touched.
Those two categories usually solve 95% of any challenges I'd had on our Urals.
So, the first item I'd look for is air leaks in the rubber carb mounts, as Vance recommended.

This "NORMAL" you speak of, doesn't sound very fun...

Dropping idle...Cool! Just run the idle higher...let it go down once warmed-up...Unless you want it to idle like the [misinformed] Harley Kids.
Otherwise...I would be looking at the Enrichers...Make sure they Seat when off...
