CB1100 Idle speed instability problem

[Riko_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.

since the replacement none at all

bring it to the dealers and show him my vid



than ask him to fix it under warrenty and to make an official complaint.

There have been complaints made in Thailand, Taiwan, France, Germany, Belgium, Holland.

Honda can perhaps find the issue if everybody turns in their throttle bodies for inspection and hopefully find the root scource, wich finally can result in a recall for better parts.

Dealers can be asked by Honda to bring in the parts they changed to check if the dealer didnt replace anything they shouldn't based on a spotchecks.
That way Honda can compare similar cases and inventorise the cases.
According to the dealers they have 6 months to do so, afterwards those parts are destroyed because they obviously can't keep the parts.

You can imagine if Honda gets a lot of these expensive replacements (whole throttle body is worth more than 2600 euro's) the whole process will go faster!
So make it official and don't do custom repairs.

As far as possible solutions, a whole throttle body replacement is the ONLY 'solution' to this problem.
I base this from experiences read on the 2 Asian facebook pages of our bike, Thailand and Taiwan.
Also some suggestions on the French and German boards did not work such as disconnecting the battery for a short or long period.

Ps are you on the english board as well?
How come all those members are the most passive bunch I've seen?

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.

I do have a good relationship with the dealer, so hoping that will see me thru.
As it's a common problem and a recognised fault... even if un-known fault, I'm hoping that the mods won't matter. If it were just me then they'd have a fair point, I'd say.

Thanks for that Riko,

I started a warranty claim yesterday, and I'll forward your vid and findings.
Defo. something a miss and they need to sort it out...

I've just heard back from the Honda dealer about this issue. Apparently a bulletin went out to dealers about this problem a couple of weeks ago and they are planning to install new mapping to the ECU. A disk is expected at the dealer in a week or so. Apparently, the stepping motor is shutting down too quickly or by too much, causing a low/erratic tick over.

I'm not sure what that exactly means as I've just got off the phone to them. I'll have a look in the manual and see if that sheds a little light on it...

[Riko_imp]

Interesting, its ECU related....curious to know if there will be call backs

[beardyweirdy@me.com_imp]

Possibly, if it's a ECU software thing then you'd think that all the Twin Exhaust, EX models of that age would have it. They probably have but unless you run your bike in the city then it most likely won't effect you.

I've had my ECU re-flashed by Guhl Motors. I'm wondering what effect writing the new mapping to the ECU by the Honda dealer will have on the data written on there at the re-flash.

Might contact Guhl Motors and see if they have any idea...

It will completely overwrite it. Your reflash will be gone and you will be back to the stock OEM mapping, with whatever changes Honda made. I believe Don will reflash the thing for you again but if you have had it flashed, I doubt whatever Honda is going to do will be of any additional benefit.

That kind of work is usually done online. The tech plugs your bike into a computer, which is connected to the Web, and it checks for the latest firmware and programming for your VIN. If there's a mismatch it'll update your ECU to the latest version. The tech will probably never even see what is done, nor have any idea of specifics.
