CB1100 Idle speed instability problem
(10-09-2019, 07:29 PM)zirconxi_imp Wrote: Bikes at 33500km mileage, rode for 6 hours under hot weather last Saturday, while returning home the bike suddenly gone into high idling while waiting at traffic lights to turn into my housing area. 1st time it happen. Stop engine and restart doesn't solve it. unplug and plug back EOT then she return to normal (I had my finger burned trying to do this).

Trying to find the cause online and end up reading 61 pages in this tread for the past 3 days (not giving up yet, will continue again). From what I have read, it seems like this problems can be from multiple fault, but all giving same symptom. hence some method works while some don't. Anyway, i updated the spreadsheet with my details (I deleted some lines which are empty without any data. i double triple check and its all empty row. hope i didn't delete the wrong thing.). hoping others can find their solutions.

My friend's CB have the idling too slow and engine stalled problem as well before this, but he solved his by spraying something into throttle body, to clean it he say...

zirconxi, as one who had high/low idle issue, sorry to hear your bike is acting up.

I think it was SportsterDoc who came up with a trouble-shooting list of where to start from simple to more complex possible causes--I searched but couldn't find it. Dave in San Diego outlines the more complex fix--the IACV.
