CB1100 Idle speed instability problem
Hi Nemo and thanks pdedse for the list, actually 2 iacv replacements have been succesful, johnf replaced by dealer and magnus done by himself came right after some time after replacing iacv, both are still fine to date.
Dave is in the process of replacing his iacv and would be the third one if succesful, as you may know the iacv is not expensive, just a lot of work to get to.

What may help you in the mean time is using the "engine off" switch on the right handlebar when it has high idle, it resets the iacv position among other things.

It would be interesting to know for us if the high idle is present all the time or starts some time after the engine is warmed up, so starts at 1500, settles at 1050 and then gets " stuck "at 1500 again after some time?
