CB1100 Idle speed instability problem

[ericlo69_imp]

Update:
Here in Taiwan, recently HONDA released new (revised) ECU program to solve CB1100 idle speed problem; some owners start to send their bikes to dealer side for new ECU program uploading. (BUT there is not RECALL from HONDA Taiwan dealers). One owner mentioned that his bike (EX model, Throttle body assy has been replaced before because of idle speed unstable) is getting smoother and more powerful after uploading.
Just for your reference, and I will keep it updated.

This owner just said that idle speed problem happened again after new ECU program upload, it seems THIS "new" ECU program is not the right one for problem solving!?
BTW, another owner (14' EX model, this case has been mentioned in my previous posts #31,84) suffered this problem seriously for a long time; few weeks ago HONDA technician replaced the whole ECU (not cheap). he said: improve significantly & so far so good, but need to keep testing.
