so after searching and reading for about an hour about everyones trouble with keeping an F4i idling, my problem hasnt been addressed.
Like many others, after my bike warms up it wont idle at all and will die on me if i close the throttle while at a stop.
now I checked my battery and its putting out a healthy 12.5 volts and the terminals are nice and tight. I just had the shop check the rectifier and alternator when I had the bike in for its 32k service and they checked out A-OK.

So now Im at the end of my rope. Anyone with any ideas?

 

Try the idle adjustment nod on the left side of the bike if you havent or already!! Read the manual because you can turn it and adjust the idle! Or it might be your cpu...or ems...

 

I'd also think the Idle Air adjustment should solve your problem - Someone didn't try to adjust it down while on fast idle (as the engine warmed up). - If it idles fine during the warm up, but when the temps start showing up and it starts to slow down, is that when it kills?- If so, just crank on the adjust **** up till it's at 1300 or so.

 

yeah, the **** was the first thing i tried before checking everything else. turning it doesnt make a difference either way, doesnt speed it up or slow it down...

 

I haven't looked, but could it be unscrewed to the point of not engaging? or could that cable be broken? - You'd probably have to lift the tank and remove the airbox to check those things out - I still think that's the source of your problem...
