Sorry that the IACV replaceent is so challenging, but you are doing a great service to the forum by reporting the details.

Does it appear to be any easier to replace the entire throttle body assembly?

Hi Doc. To answer your question, no. I have to remove the entire throttle body assembly prior to removing the IACV, and once I do this the IACV is easily removed. The problem is my hands are too big to get to so many of the areas where there are clips, screws, and hoses to remove. It's just funny how disassembled my bike is right now (with the rear wheel removed) just to replace a single valve. I miss the good old days with carburetors that could be easily removed in the matter of few minutes. I can take the fuel tank off my 1976 C750F in less than two minutes, with no tools required. And I can fully adjust all of the valves in about an hour.
