The IAC is stable and has been so for days. Further, the adjustability of the IAC is, in a word, precise. The TPS is stable and likewise precise. Both do what they should, how they should and are adjustable like they ought to be. The only variation I have seen is the IAC will drop below 30 between 80 C ET and about 95 C ET but at 110 C ET it rises and stays dead on at 31 and stays there after the bike is warmed up. The log shows a slow moving, steady and linear movement of the IAC without jerks or spikes up or down. Amazing.
Looking at the stock TB, it appears to have heat sinks around the IAC to TB boss interface. I suspect these FINS are not decorative.
I am beginning to wonder what effect a heat insulating (polypropolyene) spacer would do when placed between the TB and manifold. The Kuryakyn will accept that spacer since Kuryakyn sells a spacer made out of aluminium which enables the TB to fit other bike models: make it out of polyp. etc., maybe like the insulators used on carburator/manifold interface. Then again, who knows.
