I don't notice it at idle but coming down from speed with my 2007. But parodically have to clean the IAC port. Behind air cleaner, 11 oclock port, spray sensor cleaner in as you cycle power. Should hear little motor.
I notice my idle dipping as I slow down to stop. May not fix, but is good to do. I think there is a bulletin.

Reading comprehension is not your strong suit, he already said the IAC was replaced.
Now, go back and read LINE BY LINE........go back and think about what you just read, close the thread and go back to mommies basement

OP, How many miles on the bike?
Check the TPS sensor on the throttle body first.
How old is the battery?
Charge it if you can and then take it to a local auto parts dealer and have it load tested.
Seen some STRANGE things happen with a weak battery.

TPS check was good
I wasn't there when my friend replaced the pump and filters . I've seen some others say it could be the pressure regulator leaking or hose after regulator.
That's my next check

If it's low you should NOT hear any fuel spraying in the tank when you turn on the ignition and hear the fuel pump prime.(You can also use a flashlight and SEE if there is any fuel spraying)
The spray wont happen with a full tank as it's covered in the fuel, only shows when the level is low and below the bulk of the fuel system.
If you DO hear some fuel spraying, then I'd day there is a leak in there.
I doubt that's the case as installing those new parts pretty much insures they are tight, IF he did replace everything in the tank, Filter, Regulator, screen and hoses.
Its bit of pain getting the whole system out and back in as it has to be folded INSIDE the tank to do that.

And in my experience the leaking in the tank was a hose rubbed on a brace and got a hole in it.
When changing the hoses and filter and such you re-route the hoses away from that brace so it doesn't happen again.
And the issue produced hard starting, not rough idling.

Very happy you got it running.
Ya know now that I think of it, there was a thread about the cracked regulator occurring frequently about 12-13 years ago.
Totally forgot about it.
Ride on man!!!
