Well, if you allow me to go back to topic?

I follow this thread for 5 weeks now, and got more involved in the last 2 weeks.
From my experience with EFI, from what I have seen, from the observations and suggestions by others, plus a bit of actual measuring, I remain with my conclusion that the final cause of the stalls is a lean mixture. This was and is confirmed by measuring the exhaust of 2 bikes.

Of course the lean mixture is only at the end of the total process, and is caused by one or various reasons.
I still suspect that the mapping is set on the leans side to pass the regulations.
However, the ECU is only a part of the system, and in order to be sure that the ECU is the culprit, you must be sure that ALL OTHER equipment (sensors, connections, electric cables, power supply, etc) are fully functioning, calibrated as they need to be, clean and without any other problem.

What I see happening in the last week, is that not only the factory, but also some of you are loosing their patients.
I can understand that it all took too long, that the factory service is non existing, that that that.

But what I miss (and what I surely had done in the case I had a Jialing) is to go back to the basics first.
Clean everything, set every sensor, every switch, everything, according the manual factory settings.
This way, and only this way, you set a proper base, and allow the rest of the testing and trying to be successful.

Instead I see some people rushing from service shop to service shop.
I see service engineers without knowledge, without interest and without passion changing things, exchanging things, re-setting things, disconnection things.
The only result from all that is, that more and more is out of whack, and that any next "repair" is more a lucky shot then anything else.
We can not prevent the factory from acting erratic, but I think some of you might need to take a small step backwards, a deep breath and then just show some patients.

If I had a Jialing, I should have stripped it to the bottom already, just to be sure that the basics are correct.
I should then at least be confident that any further step by step approach was solely based upon the single item changed.
As said, only this way of working makes conclusions valid.

The above is not in any way meant offensive.
I can understand that I am perhaps lucky that I don't have a Jialing, and I can understand that some owners reached the limit. To each its own, no problem at that.
But I am perhaps also the person who can take a bit more distance by not having a bike, and by looking at it from a more technical point of view.

Guys, the winter is coming, give it 4 more months, take a deep breath, go back to the basics, and give it an other try.
I guess you all have learned more about EFI in the last 4 weeks then in your life time before .... imagine where we might be in an other 4 weeks ....
Well I will be in the tropics by then, but that is an other story haha ...
