CB1100 Idle speed instability problem
I didn't have to remove the rear wheel. I kept the throttle body assembly attached. I think I posted a picture somewhere in this long, long thread.

John - did you remove your rear wheel to get the fender out? Did you remove the entre throttle body assembly?

I reinstalled the battery last night and tested the old and new IACVs side-by-side. I must have cycled each one thirty times, alternating back and forth. In all honesty, I cannot detect any difference in the way they operate. But this test only checks what I believe to be only a small portion of the full operation of the IACV; I'm sure you guys who are much more knowledgeable on this topic would know how to perform a more thorough inspection.

The valve is metallic, so I assume it is aluminum. The port in the cylinder is completely clean and there is no obstruction.

My plan is to get the new IACV installed tomorrow. I will perform a valve clearance inspection while I have the tank off, but I don't know if I'll have time tomorrow to do all of this (other chores and responsibilities are calling).

Thanks again to all you guys for all of your support!
