Default 09 kingpin a never ending cold start idle

Actually, when I first start it up, it idles through warm-up very nice at about 1100rpm, then after i take off, it will not idle back down, it idles anywhere from 1600-1800rpm. After a while, if i blip the throttle a couple of times at a stop light, it will come down to a normal 1100. Vic shotgun pipes and the factory map for it are the only changes to it. Also, it i am going 25 or 35 mph in third gear, about 1800rpm, it kind of surges up and down a noticable amount. I checked both the bolts to the throttle body and the clamps to the rubber manifolds and both are tight, as are the exhaust header nuts. I have done the thrttle point reset numerous times, and no change. I also installed an arlen ness big shot tuner trying to tune it out, and no setting i have tried make a difference with the idle. I read about a procedure that Lloydz publishes for calibrating the throttle position sensor and was wondering if anyone has tried it, or has anyother suggestions. The bike runs perfect everywhere else and the milage is mid 40s. I havent tried squirting starter fluid around around the intake to check for cracks or leaks, just visual check , and havent pulled the tank to look for leaking connections anywhere else either. please let me know if anyone has any experience with this problem

IAV might be not working or there is a leak in one of the lines. I don't know how you check it to see if its bad but your dealer could tell you how. It must be something doing with vacuum to check the IAV

On the left side of the throttle body there are hoses 3/8 plastic going in front and back. Most likely the rubber fittings that go from the hoses to the throttle body are cracked, and leaking

I'm not an asshole...I just type that way

Thanks, Vision John for the reply, you are the only one to. But I was out in the barn taking a real good look and I figured it out. If you have ever other threads where someone has an eractic running motor, and people send in their opinions as to the problem, and then out of the blue Kevin chimes in with something totally another direction. From what I have read this is the number one thing he always says.
The rubber intake manifold to the rear cylinder is CRACKED!!! And it is from being misassembled. The manifold is on crooked causing the clamp to not be properly seated creating a almost fold of rubber material against the clamp which is where it tore. For as many as i have heard Kevin identify, that is a real problem Vic has with their manufacturing.

OMG!!!!!!! Yesterday, I am waiting for my parts to arrive, I took some silcone and plugged the tear in the manifold just to confirm the problem, after letting it cure for 24, I took the old Pinball for a run, that thing has never run or idled or anything like it did, it must have had a leak since i got it ( I bought it with 2000 miles and 6 months old) and just gotten worst in the last month. It idles so smooth its almost boring. The best is when going through the no wake zone (driving through my neighborhood to get to the main roads) at 30mph in third (basically a no load situation)and no more surging, just smooth, steady thumping. I cant wait to get the new manifold and seals on and have everythng positively sealed up. I have one
Screaming Eagle dyna, with his ported heads and 110 cu in that was a absolute even run, that I need to have another talk with. I appreciate everyones input because even if it wasnt the problem, I keep it in the back of my mind of things to check in the future.
Enjoy your rides, I know i will even more today
