So is that air filter still in your Amazon cart or did you finally install it?
Could be a bad batch of gas.
What's the warm idle speed?
Could be water in the gas.. Could be a lot of things.
Has been more than one tank.
I think about 800rpm? Cold seems to be something like 1100. Are those even externally adjustable? I seem to remember looking for an adjuster and couldn't find one. Even if it is just a stop gap, it might be worth messing with.

Hmm, I will investigate.
I know That is why I am a bit concerned. It isn't a major problem, but it is annoying.
Yes, it is externally adjustable. In fact, Kawasaki ran a cable down the left side of the bike and put a knob on the end of that cable so it is easy to adjust. Look around the drain tubes in front of the left peg, just inside the mid fairing panel and you will find that cable.
In major maintenance inspections at 25K and 50K miles the only thing I found changed significantly was the throttle body synchronization. The mechanical linkage between the two T.B. banks, 1&2 and 3&4 wears a bit and so the two groups of two T.B.'s get slightly out of synch. This hurts both idle and off- idle initial acceleration at low throttle openings. Otherwise, there was nothing that needed to be changed on my bike even at 50K miles.
come on Max... 40k miles... no valve inspect.. and air filter still in package waiting for that elusive valve interval... It's time man... get'r done dude.. don't be the poster child for "it ran great right up till she blowed up..."
I know, I am so bad. I have never removed the gas tank before (even with all the farkling over the years) and I am very leery to do it without my friend helping. Otherwise I would have at least replaced the air filter, coolant, and dumped the gas tank on my own. Really, the ONLY reason this stuff has not been done is because of him not being available and my not trusting the dealer to do it right. I wanted to do it all at the same time (I have quite a list now- all that plus leaky cam seal, valve adjust, TB sync, header bolts, windshield lube, inspection of stuff). I will start actively pestering him again.... I think he is much more "stable" now.

Is it behind the panel? If so, that might be why I remember it but didn't find it. I would check now, but it is raining AGAIN.
OK, it stopped raining long enough for me to finally look and test. First up- the idle adjuster. Nope, there isn't one (just like I thought). So I have a feeling it has some how ended up behind the fairing. There is no easy getting to that any time soon. It is going to start raining again in probably an hour.
Next, I videoed starting the bike cold so I could study it and time it. 73F ambient, 75%RH. After starting, it hovers erratically between 1300 to 1600 rpm. At 40 seconds it starts to lower slowly until it hits 750rpm at 1 min 10 seconds. That is where it stays, just barely running. At 2 min I reved it some and it returns right back to 750. At 2min 40 sec, still at 750 and I turned it off because it started raining (of course). I really wanted to let it run longer to see where it would end up as it got warmer.
So.... Although there is a list of stuff that certainly needs doing, I think I need to get to that idle adjuster.
