Bought a 2014 CB1100 EX with 6100 miles on it in Feb 2016, with over one year of warranty left.

Issue occurred three times over the last 10 months (high idle condition). The first two times, the dealership reset the ECU, which treated the symptom, but did not resolve the issue, and the high idle condition returned.

The third time I took the bike to the dealer, I demanded that they keep the bike until the issue was resolved before resetting the ECU. Honda sent a tech to the dealership and they determined the IACV motor was sending faulty information to the ECU, thus causing it to enter "limp mode." The dealership replaced the IACV motor (this was 3 months ago) and the issue has not returned.

I have 3 more months of warranty left, and I hope the condition does not return. Let me know if you have any questions.

John, to be clear, you're in the US, right? Did you buy an EX—the European model—or the DLX model sold in the US? If so, you are, as I recall, the only DLX owner to report this issue.

Cormanus, I have an all-black 4-into-1 exhaust with alloy rims. Not sure where that lands me.
