Checked needle - ok. Just seems to be running lean mixture... Will get to adjusting it first thing tomorrow morning.
This procedure, each time before you go to work, you can do step by step, or more precisely, tight (to make richer mixture) or loose (to make a leaner mixture) mixture screw in steps of, say, 1/8 of full circle (at least I did that way), not at once (unless you have experience with carbs... or "Colortune" kit.... or CO2 analyser...).
A quarter of a turn of the mixture screw solved both: the white smoke problem and the unstable idle problem. The bike's torque curve became more, well, curvy and less flat. Thanks all :)
Do you think that you solved the problem? You may have alleviated the symptoms but not resolve the problem completely.
I would still check color of spark plugs electrodes. If you are not pouring some local OM gasoline with only-God-knows-what-kind-of-supplements, grime on the electrodes is a very reliable indicator of air and fuel mixture.
took the plug out, seems to be ok...
Take a job big or small do it right or not at all.
Plug Chop
Sure. Did the plug chop test yesterday with the new plug so as to be sure of readings. Brownish color - seems to be fine. White smoke's gone. Stalling gone. Stable idle, doesn't cut off at sudden stops. Way better than it was.
Bet that your relieved, now you can just enjoy it.
I am :) Except for one thing: the rear light assembly somehow loosened itself and just fell off hanging by the wire. TIC. Should have checked all the bolt connections and probably loctited them. It must be vibration that did it. Tightened it up yesterday hope won't happen again.
If you're going to take out tool box, use this opportunity and check all the rest screws and bolts.
BTW, you wrote that behind you more than 500 kilometers. Have you changed oil so far?
Changed oil 300km into break-in. The next change is pending at 800km.
Since the bike seems to be running fine and I've tightened everything up, I decided to treat it to a couple of bags.

You miss only a sheep skin seat cover to complete the picture. :riding:
Let me guess: you had some trouble to find suitable side bags?
No, not really. Just typed in "leather side bags" on taobao and got like a thousand offers. these particular ones aren't for this bike exactly. Though the front one is universal, the side bags were advertised as specifically fitting a CFMoto "Baboon" bike. I gave it a shot and I like what came out of it.
I asked this because I noticed that the rear turn indicators are placed not quite "sidebags friendly", not allowing installation of some bigger bags.
Right. In fact I had to bend the blinkers a bit to accommodate the bags. They bend quite easily, btw. Could probably remove/re-fit them altogether but didn't take the trouble doing that - those bags are enough for a raincoat and a full-size lock, they're leather, they look sexy. 'nuff for me.Quote:

Which might have been the design inspiration for whoever crafted them :)
OK, so the bike's been fine. More than that - I rode it to 马鞍山 and back without any problems whatsoever. Sits happily at 80km/h two-up. Can go more than that, but that really strains the engine. I guess will cruise at about 100km/h solo easily.
BTW, I somewhat cafe'd it just for the fun of it.

Those handlebars were about 130 yuan from taobao. Good quality, fast shipping, easy setup. Look nice too. Actually, the repair guy said the bars were better than OK and he saw those for the first time. They're 31mm so I guess will fit majority of 150-250 cc bikes. Had to be carved out for my bike, though.

Bar-end mirrors are Rizoma ripoff, almost 200 yuan, CNC-d. Look kickass, definitely a headturner. Thought they'd be inconvenient and now I understand how wrong I was. Those mirrors give a wider viewing angle that the regular ones do and they have some reflective or light-absorbing coating (I think the call it anti-glare, but I'm not sure), which is very helpful riding sunset/night.

OK, so today the almighty QingQi lost spark right on the road. Which means I was late for class which means trouble. The bike's new, hasn't been abused, hasn't been ridden hard, has been properly maintained and taken care of. Now, QingQi, I got a question here: WTF?
Check your ground on your kill switch, maybe it was weakened, and subsequently lost with the handle bar change. If not then you or your mechanic have to work backward from there to figure out what is failing.
Thanks, will check it after 20:00, after I get off work, that is.
And buy decent quality CDI, coil, spark cap and cable. They are cheap and might come in handy.
Isn't Qingqi had warranty http://www.qingqi.com.cn/sanbaoxize.aspx, just go there for a FREE checkup in spare time.
OK, so things are as follows: there's a plug from CDI to wiring harness located under the seat. Apparently, when the bike was assembled the plug was plugged but not plugged "to the click". So it unplugged itself. No worries - plug in, click, bike starts. CDI, coil, spark plug and cable seem to be of decent quality and aren't yet subject to replacement. Seem to be OK for the moment.
P.S.: stupid me :)
It is usually something simple it just takes time to figure it out. The Qingqi bikes are decent bikes.
I would like to have one of these and with the 200cc engine blacked out.
Qingqi had a 150 which known as K157FMJ http://www.mtuo.com/news/html/201207...34651107_1.htm
That engine can found on these bike:

MJH, that Suzuki bike is one awesome classic! Does it have any other kind of wheels, though? Like spoked ones?
humanbeing, Yeah, QingQi does have 150. Wonder why'd they put the 125cc engine on this machine?
Мaybe I missed explanation, but I must to ask: why in China there are almost the same models of motorcycles, with similar performances, one with 125 cc and other with 150 cc?
OK, why these categories there existed, for example, in Italy, it was clear - by their laws, with 150 or more cc can you ride on the highway, with less - no. Is it the same case in China?
No it's not. Here no matter how large/small your bike's displacement is, you can't take the highway. Which means that even if I get a touring Harley I still can't use that convenient new expressway system. I'll have to take those bumpy rural roads that all those 3-wheelers, cabbage bikers and horse riders take. Those roads have recently been improving but not much. Oh, and the speed limit there is 60-80 km/h.
Then again there is no license restriction, like LAMS for instance. Once you get a motorbike license you ride anything no matter 50cc or 2000cc. I think that's because until recently everything above 250cc was banned.
I can't be sure but I think that 125-150cc diversity is the result of trial and error policy that many (all???) Chinese manufacturers implement. I don't know of one Chinese company that would have a clear roadmap with milestones and coherent development plan. They produce "whatever" and then guinea-pig the market observing what of their "whatever" customers enjoy most. Then they cut off everything else and "focus" on the product that is welcome. Customers lose interest - product run is claimed complete, the product is phased out, another batch of "whatever" is launched.
I saw that happen with Chinese mobile phones, cars, bikes, furniture, TV, computers, laptops, clothes, websites, toys, shops, schools and what not.
In a state-run motorcycle company, you make motorcycles. Lower-case motorcycles. Generic ones. Just like everyone else makes. You have no incentive to make something better, to get close to the customer and understand their needs. So you just copy whatever seems popular, and make it in the millions, cutting corners to cut costs. So everything is basically a crappy, lower-cost copy of everything else.
To my knowledge, China has never had a "ban" on bikes over 250cc; that's an urban legend that is obviously refuted by the CJ750 among others. But because of the industry's utter lack of marketing savvy, and its lemming-like replicative nature, all bikes are in the 150-200cc range because that's what's already out there to mimic. To make a different bike would mean doing some marketing, some design, some innovation, nay, some thinking, and, of course, that means to stick your neck out. Why put your 2500 rmb/month salary at risk by doing that? Just copy what's out there, and cut corners to make it cheaper, and be safe. It's the Chinese way.
Every notice what happens when, say, a Sichuan restaurant gets popular somewhere? Three other Sichuan restaurants open up nearby, and within a year, all four fail. Clever strategy!
Have a look at MJH's indefatigable postings about China's motorcycle production numbers. They are falling, falling, falling, even as China's economy supposedly booms. Hopefully the emergence of the Chunfeng/CFMoto and Qianjiang/Benelli 650s signals a dawning awareness that the way to succeed is to make something fresh and different, and even command a premium for it. We know for a fact that Jialing and its JH600 are feeling the pressure from these new mid-displacement models. It's an open question whether they will be able to respond with intelligence and skill, but I'm not holding my breath.
cheers!
