JH600 stalling

[Lao Jia Hou]

I don't think the JH600 has a high compression piston running 97 octane will not do much for engine performance although it should burn/ignite better.

We went that route for a while, suspecting improvement from 97, but nothing really changed. The JH600 has a low 9.7:1 compression, which was one of its attractions to me, given the low quality gas found throughout China. When one gets up into the double digits compression, fuel becomes a huge factor.

Has Jialing or any Chinese motorcycle manufacture ever had a product recall not trying to be smart just wondered.

Alot of euro and Jap manufactures are slow if at all to implement a product recall.

Not that I have heard of - I have seen a few automobile recalls in China.

Last time I rode with LJH, he definitely wasn't enjoying the JH600. He did more stalls than clicks that day I guess.

Yeah, and that was on my "A" ... my "B" was considerably worse until this total makeover. Now, the "B" is stalling only a couple of times on each little trip. I took it out again today, after receiving it back yesterday. Ran it from home to Tiananmen and back. A couple of stalls in each direction, one at a very bad time (3 lanes merging into 1 and I was getting squeezed ... and the bloody bike stalls).

Anyways, at the suggestion of some other JH600'rs, I've made some videos of these bikes. I'll post them after I figure out how to edit them, cut down the file sizes and upload them to Youku.

... any stalling that's not related to driver error is unacceptable. I'm in California riding my KLR right now, and it idles like a purring cat. Never ever stalls. What a difference! Motorcycle engines simply should not stall of their own accord.

Most of my life, I've been poor ... riding buckets of bolts held together by nothing more than a prayer ... but I've never experienced anything even remotely similar to this. Bikes should not stall, especially EFI bikes. Man, I never thought I'd be fondly remembering quirky carbs as "the good old days".

LJH,

Did you ever try giving Mr Li a call over in Hefei, Anhui Province? He has lots of experience keeping the Military bikes going.

I only experience the stalling once in a great while. Last half dozen short rides have had no issues but I only have a couple thousand kilometers on my bike.

Maybe it is the location and fuel differences. The local Ford and Mazda engine guys who have factories in Nanjing go nuts with different province fuel qualities that actually require different ECU setup depending where the cars go. IT is not widely known for obvious reasons but maybe we suffer same thing with the JH600 depending on the fuel for ECU to be at certain levels that are not maintained.

Anyway, I would call Mr Li and try to get him to come to Beijing if you can. He has been the solution to my problems.

Thanks TA. Actually, the Beijing guys are rather decent, also looking after the military bikes. But I kinda get a sense from them that no matter how hard they squeeze, lemonade just isn't coming out.

Both of my bikes were ok, at first ... but with miles, the stalling just got progressively worse and worse. Now, the "B" is completely rebuilt with all new/updated parts. It stalls only once or twice every few kms. I've got about 6,000 kms on each bike - which, in my books, is still brand new. I am totally anal about servicing and adjustments - my bike never moves unless its chain is adjusted perfectly, etc, etc, etc.

As a end note - before my "B" went in for its makeover, I took it around on some errands. It was a cold day. It only stalled half a dozen times (normally, it would stall this amount before getting out of my parking garage). I immediately suspected a dirty/faulty Mass Air Flow sensor, or maybe the ambient temp sensor. Alas, the next day (also cold), the extreme stalling recurred.
