CB1100 Idle speed instability problem
Just did a 60 mile round trip on my bike; mostly freeway (70+mph), but a few miles of stop and go. The bike ran perfect, idling smoothly at (approx.) 1050 RPM at every stop. So I decided to give it a test and rode through the city, doing about 15 minutes of 1st and 2nd gear speeds, with a lot of stop lights. The bike ran perfectly all evening, actually it has never run better. Usually the stop and go traffic, and slow speeds, would bring out the idle problem (both the low RPM / stalling, and the high (1,500) RPM conditions, but not this time. It could be because it was cool out tonight, or it just needs more time running in these conditions to bring the problem back, so I won't say the problem is cured at this point. But, I don't think that my initial thought that the WFO ride cleaned the throttle bodies out is accurate because as I reported previously in this thread, disconnecting the EOT sensor caused the bike to run perfectly every time. So, is it possible that the computer somehow adjusted something that was connected to the WFO ride? I don't know enough about these systems, but maybe someone else on this forum has some insight? I will keep this thread updated.
