CB1100 Idle speed instability problem

[Ulvetanna_imp]

Wow, I just found this thread. I've been having the exact same problem for quite a while. Same, when in heavy city traffic, 20-30 mins in. I've been turning the ignition Off/On to re-set it. That worked as the kill switch on Riko's bike.

I had it down to lots of things, all of my own doing, PCv, Flashed ECU, Air intake mods, Cat Free Exhaust... etc...
Quite relived to find it's not down to my tinkering but obv. not happy to have a faulty bike. Esp. as the Warranty is up next month.

I have the same model as the other faulty bikes, EX 2104.

Riko, have you had any trouble since having the throttle body ass. re-placed?

Thinking I should start some sort of warranty claim before it runs out.

The reflashed ECU will void your warranty. If you reflash it to stock before going to the dealer you might be all right with that. I am uncertain as to how the removal of the catalytic converter and other modifications might affect the warranty, but the reflash will definitely have an adverse impact in that respect.

I know of some riders who keep a second ECU around (purchased on eBay or similar) to install to meet warranty or regulatory requirements.

On the other hand, if you have close relationship with your dealer you may be able to find a way around all those modifications.
