CB1100 Idle speed instability problem
(01-13-2017, 09:04 PM)Lord Popgun_imp Wrote: I wonder if there could maybe be an issue with the plastic throttle body warping causing a binding of the IACV operation. Just throwing it out. I'm not taking mine off to see exactly how it works.

The throttle body is made out of plastic? Yeah, after taking a look at the '13 service manual, it looks like a big job to inspect/replace the IACV.

On page 5-6 of the '13 service manual, if idle rpm is too low, the IACV may be stuck closed. If idle speed is too high, the IACV could be stuck open. It seems a "sticky" IACV could be causing some of these problems.

[url=http://cb1100forum.com/forum/showthread.php?tid=9520&highlight=oil+temperature+sensor]kmoney was having problems with high idle speed and found that by unplugging the connector to the EOT sensor, the idle speed return to normal. However, I couldn't find any post by him to see if replacing the EOT sensor solved the problem.
