CB1100 Idle speed instability problem
Dragging up a bit of an old thread here, but...

I'd noticed recently that my Idle speed wasn't as smooth as it was. It was a bit like having an old school choke where it wasn't happy when running from cold. Once warm it's all good, so it's not massive problem. I also noticed that the sound of it operating when you first turn the key was quieter than it used to be.

Thought maybe it was gummed up and though about stripping it down to inspect it.
I had already been thru the diagnostics with a meter, as per the manual and it all checked out in spec.
As the results from the meter were good and it wasn't a massive problem I decided that I was being a fuss pot and it wasn't worth the Agg. of stripping it all down, so I've left it till, it gets any worse.

Reason I'm posting is that I looked up on the parts list how much a new one would cost, if it were knackered, and saw that Honda have changed the IACV on the new 2017 models.
New part number and £160 as opposed to the £106.
Could this be the cause of the problem we've been having?
Pure speculation and gossip mongering but thought it was interesting to change such a part.
