JH600 stalling

ECU box number:

More specific? The number in the biggest fontsize with the Jialing logo in front of it?

** UPDATE **

Jialing (Chongqing) is "getting back to us." We've also had pretty good support from the Beijing Service Center, who has written an "official letter" on our behalf. I don't envy those guys at the Service Center - I have a funny feeling that CQ isn't really that helpful with them, either.

Motokai, thanks for organizing the data compilation - I'll fire mine off soon.

Eric, again ... thanks. You certainly deserve some ice cream from us.

Well, I am afraid it is not over till it is over ... but who knows?

I certainly should try to make the database as big as possibe.
I saw various other threads of riders (overseas) who have one or two, like the guy in Holland who has a single and a sidecar version.
You might browes half an hour the forum to search them, and approach those guys as well.

Good luck, on stand-by!

** Jialing (Chongqing) Update **

Jialing (CQ) senior people have responded to a joint submission from the Beijing Service Centre and myself. Jialing is aware of the "problem" and is actively working with Bosch, as well as other "potential causes", and has given a firm commitment to resolve the problem. It is aware that this is a problem across almost all bikes, and that the stalling problem surfaces most commonly in the 5K to 8K mileage range. It is also aware that the current "fix" (part replacement) will result in the problem having a recurrence in the next 5 -> 8K range.

Jialing (CQ) has instructed me to hand over the most serious stalling issue bike (which would currently be my "A") and it will use it as one of its test/research bikes.

Jialing (CQ) has told me that once a permanent solution is developed, it will make arrangements for all affected motorcycles to be repaired/upgraded.

Hence, at this point, it seems to me as though Jialing is indeed making a genuine effort - the coming weeks will be more informative. I will turn my "A" over to Jialing later this week.

Cheers.

Great progress indeed, LJH!
I am wondering if the response from Jialing is a formal letter or not. If it is, is it allowed to be shared?
I am also wondering how we can get Eric involved in this Jialing effort, given the fact Jialing has been working on this issue for so long without much to show and some fresh new ideas from someone with extensive experience working on many big bores probably won't hurt.

Well, that is already one step further then expected, congratulations.
You must have a great wife who got so far with Jialing!

I just wonder if they not only acknowledged the problem, but gave you a hint on what they think is causing the problem?
Cause I guess if the workshop just receives your bike without proper instructions from Jialing, they might just start to change wheels and so, preying it will solve the matter ....

As to Milton's remark:
I guess the above is the most important.
If Jialing has a clear idea what the problem is, and how to solve it, it might go pretty straightforward.
I still believe strongly that it is fuel related, but I am by far an expert on the Jialing bikes, so let see what they will come up with.
As long as you keep me informed, I can act as a "background" think tank for Richard and you, and give you my view on the case.
As long as we force them to give straight answers (Like: What should the CO % be at idle), I guess we can kind of control.
Of course I don't mind to eat my ice-cream in the Jialing factory as well ...

Thanks LJH!

Was out riding with my duc friend (little 600 Monster) the other night and my JH was stalling at every other intersection - frustrating.
Also, was experiencing something new for my bike - the Idle Stall: While sitting at the intersection waiting for light to change it would just cut out (this was not a low idle stall, but a true "cut" of the ECU). Anyway, if CQ needs a 2nd bike to work on, let me know. While I'm hoping for a solution, I'd settle for the temp fix just to get another 5K of solid riding! It's a great bike.

You forgot to mention how smooth that great "little" Monster was running

Dear LJH,

Good news indeed. Makes me wonder whether someone at Jialing perhaps learned a little English and has been lurking in MCM. Actually, I hope that's the case, and that they indeed are motivated to burnish their reputation with their customers.

Like Milton, I too hope that they let a little fresh air in and share their findings with all of us.

I also still believe in the tooth fairy.

And I also like what Motokai said: (Apart from the stalling, and the fork dive) It's a really great bike!

[998S]

Apart from the stalling, and the fork dive

If you have a problem with fork dive, you can experiment with some thicker fork oil.
This will stiffen up the compression and rebound, and you will notice a less pronounced dive (but also a stiffer bike in general - good if you join us on the F-1 circuit....).
