CB1100 Idle speed instability problem

[Cormanus]

To tell you the truth Doc, I don’t think any real troubleshooting has been done by anyone. At least not what I would do as a technician, or you as a bike repair specialist.

I wish we could find a common cause for this. So far the fixes have been all over the place. Some had actual failures (at least one IACV) and some cured the problem without really determining the failure (think Rico and the dealer changing out the throttle body), or even a software update for one member somewhere in Europe (Honda of America says there is no update).

As member’s bikes develop the problem, they don’t want to read 56 pages of comments (don’t blame them) and thus the same info, like the EOT affects idle, come out. Yes I know, it COULD be the problem that bike.
