I've got a bouncing idle problem much like the guy in this video. It happens to me once the bike warms up a bit.

As far as I know, there are a couple of possible causes:
-ECU needs to be ran through to remap itself after having the battery disconnected.
-Mixture likely running lean due to two brothers pipes (one cat remains along the bottom)
-Throttle Bodies need to be sync'd
-Idle Screw might need a tiny tweak
-Cold Weather
I picked up a Power Commander, but only recently learned about the fact it cannot change the fuel mix below certain thresholds due to the closed loop nature. While the rest of my intended fixes (throttle snatchiness, RPM deadzones) will still apply, I thought it might give me a shot at fixing the bouncing idle through enriching the mixture slightly. In this regard, I'm stuck as to if there is something else I could do to fix the closed loop portion. The only ideas that comes to mind would be to remove the O2 sensor to prevent ECU correction and allow the PC to override it, and using smog block off plates. Would either of those work? In regards to the PC3 maps and smog plates - would using an aftermarket air filter cause my mixture to run more lean, or would it be a relatively safe upgrade to allow the bike to get more oxygen as required?
I'm going to be syncing the throttle bodies soon once the weather warms up a bit, and am in the process of getting the parts together - if only the cursed vacuum connectors could be easily found near where I live. Thankfully Napa has pulled through for me and I found some proper fitting pieces that will allow me to continue with construction. This might even out a cylinder that's either surging or loping and throwing the idle off - plus improving bike handling. In addition to this, I might give the idle screw a little tweak to see if it smooths out by adjusting it up or down slightly.
Edit: Maybe plugs and coils?
Not a lot of people seem to have this issue, but it worries me since I want everything running as best it can before I get out on the road, and I'm interested in learning about what my options might be to fix it. Any further input is appreciated!
