CB1100 Idle speed instability problem

[Riko_imp]

or the kill switch acts as a kind of reset for whatever is faulty with the idle speed?

anyway, i red it here, someone used the killswitch to make the issue (temporary) go...

I think its in this topic

Okay so today I brought the bike in, and told them the issues, but they didnt know...they were clueless.
btw I just said my problem, they did not look at the bike.

Mean reason for the visit was to make an appointment, so I made a deal that at the end of this month I will bring the bike in, so they can figure it out for a whole week.
Meanwhile I will make a video to show the issue.

I fear when that week is over I will not have a 100% working as it should-bike.

At the mean time, they did make an official complaint to send of to Honda Worldwide...so the whole procedure has started about this issue I and (so many?) others (in Taiwan) have.

I feel this is going to be a long term thing to deal with.

Fortunatelly, I can ride the bike for about perfectly for about 90% of the time tbh.
If I do long trips the bike is 100%, but if I do only city riding when the issue appears, I can somewhat anticipate by pushing the killswitch, at an convenient moment. hmmm

Luckely the time the bike wants to die, there are already moments in advance you see its struggling...so its not that bad that the bike is completely unrideable and I just wont let it come so far that the bike dies.
Bottom line at this moment: anticipation is the key.

When I have made the video for my dealer I will share it here as well....I would not be surprised if the issue will arise on more EX models.

But still, this should not be happening to a brand new bike from Honda..

this is the video I made that will fix my bike, do you hear this Honda, FIX THIS!!!!!

Riko, this video shows the problem very well. In my opinion, this really is a safety issue!! Honda needs to look into that and maybe even do a callback when they find the root cause.

I hope the problem can be fixed for you, but I also understand your frustration about the CB.

many greetings, fruno

ow well, i try to see the positives in all this

Its convenient you replied, because I was wondering if there are any cases like this to be read on the German forum?

Could you be so kind to open a topic in the technical/ mechanical section of the board about this issue and perhaps share the video.

Same on the UK forum, no cases....on the French board however there are cases and some are showing my video to their dealer.

Excellent video, Riko. It shows the problem very well. The part showing that the kill switch fixes the problem temporarily should provide them with a good clue as to the source of the problem.

Good luck!

That is just plain unacceptable! I hope Honda solves the issue fast. Strange only on the EX models do far.

Some mechanics i spoke with strongly follow the hypothesis its bad lambda sensors.

That could explain the issue.
Giving wrong info to the ecu causing it to idle low.
Doing this only after its on temperature, so not immediately.
Using the killswitch resets the values send from the sensor.
No error codes on the ECU.

Thinking about perhaps going the O2 eliminator way....

But later today I'll to disconnect the battery since that solved the issue for someone according to my taiwanese facebook connections..i doubt this is true, but I can only exclude that option by trying.

Most EFI systems run idle and WOT in open loop mode, and only use O2 sensors for part throttle mixture control. It's possible the CB is different, but I would be surprised if it was the oxygen sensor causing this problem.

Riko, it's interesting that turning the kill switch on/off temporarily solves the problem. I noticed in the video, you didn't try turning the ignition off and then on. Will that also solve the problem temporarily or is the kill switch the only thing that works?

Good video and I think it's good that you posted it on youtube. It may be more effective in getting Honda execs attention than going through "proper" but nonpublic channels.
