for my money, I'm betting TPS.

SPRAY linkages with lube(wd40) also lube stepper motor and make sure when you turn on key stepper moves out and back.
had the prob 2000 rpm hang up a couple of times and cleaned linkage and stepper motor and no prob since.

ok here is the TPS # T 1245113

He is a good dude and is very helpful.
Now I can see where it might be the TPS playing up or the idle stepper motor is not set up right and you should do a full ISCV reset to see if you can get any changes. I always carry a TPS with me on trips just in case but if yours is not idling I keep asking myself why and besides the TPS I keep wondering if the gap between the idle speed control cam and the throttle roller are set right. If you pulled the stepper motor and then just bolted it back on I bet it is not correct. if it is go by a Mega Ball ticket because you have a good chance at winning.
Idling problems can be picky to work out when you start understanding how many variables can creep in and mess with you. This is because of tolerances in setting the sensors and stepper motor gaps. Not to mention there is only one throttle body that is rigidly attached tot he Primary TPS which is #3 all the throttle bodies have individual throttle plate shafts and they are tied together by the two adjuster screws. If you think about it if your balancing throttle bodies and you only have to adjust #3 then you are moving the TPS sensor when you adjust the screw. So the TPS volts moved and are not in sync with the original setting done at #1 Throttle body. Of course this can be negligible and stay in tolerance or not depending on the movement.
My point is it sometimes take a little while moving back and fourth until you get the optimum function.
As stated above about cleaning and lubricating all the springs and linkages can and will make things work more consistent. If I know I am going to mess with the TPS primary or secondary, or the Stepper Motor and perform a ISCV reset I always clean and lube the linkages first.

Hey another newby Welcome to the Forum tells us more about yourself over at the intro's and get ready for a barrage of Welcomes

Thanks for this info, when I removed the stepper motor I didn't mess with the adjusting screw, I just unbloted the 2 screws and slid the linkage off, maybe it did get out of adjustment but bike was having "no idle" issue before I did that.... I don't know really...

Yes your right but my point also is did you check with tune ecu to see if it was set right before you pulled it? Of course I believe in having a spare TPS but maybe while your waiting on it to arrive you should start from scratch like your installing a new stepper motor and do the ISCV reset to see if your problem changes, goes away or is still there. Its just time no cost while your waiting for the new TPS sensor

of coarse you can always do the easy stuff after you put on a new tps.

Ok...so I pulled the TPS off, fiddled with it a bit ( not much you can do to it), sprayed all throttle linkages with WD40, reinstalled TPS and set to .6V, ran ISCV adjust.....she fired right up and idles great, I'm about 8 mins into 12 min tune.... but I have the P0122 TPS low voltage code, how do I clear it?

when you reset the TPS did you do it with the Stepper motor withdrawn or did you jut set it. Sounds to me like you just set it.
So you can clear the engine code via Tune ECU but if the error has not been corrected it will com back. I think this is because you set the tps to .6 volts while the stepper motor was in to far. You set the TPS to .6 during the ISCV reset. This way the throttle plates are in the closed position. if not and they are open some then when start the bike up the stepper motor move away to let TB close fully which is the much lower then .6 volts.
This link might help you understand the ISCV reset process.

I hope I am not confusing you. Keep the faith it sounds to me like your moving in the right direction.
Oh and error codes can be cleared in tune ecu go to the tab ECU and then down to clear error codes.
If you had the Secondary TPS out and did not put it back correctly then you will throw an error code. It doesn't just go straight in, you have to compress the spring so that the return spring is under tension (or pressure) at closed throttle.
