Qingqi QM200 USD forks info?

Does anyone know anything about the beautiful 41mm USD forks used on the Qingqi-Qlink-Pulse-Sinnis-Ramzey-Yuki-Hooper-Kreidler-Sundown QM200GY-B Super Motard?.
The parts manuals only show the complete fork, without details. There's very little about them on the net.

I'm looking for details such as dismantling procedure, oil type and capacity, etc.

These forks are (or appear to be) beatifully made, with an outstanding turned and ground finish and their action is very good, albeit a bit soft, yet no one knows who the maker is or any other details.

Their size is 41mm which seems very generous. This size is shared by such bikes as:

Yamaha YZF 750 R
Triumph Daytona 675
Kawasaki ZXR750
HONDA CB600F Hornet
Hyosung GT650
Kawasaki Z750
Yamaha 1670cc Road warrior
Yamaha R1
Yamaha YZF-R6
Yamaha YZF 600 R6
Yamaha YZF 1000 R6
Kawasaki ZX-6R Ninja

This is what they look like:

I only ever found this picture of a dismantled example, but I think they're for a Zongshen Sierra GY200:

It's not that we don't want to put up any info but that the info is not available. I'm sure if someone knew they would pitch in.

One could also dissasemble the forks, document the procedure and measure the amount of oil taken out of the fork upon dissasembly to get a rough measure. Things like specific spring weight info may be hard to come by.

I will try to write the guys at QingQi but asking them specific questions like "How much fork oil do you put in your inverted forks on the 200GY-A(B) model" might slip through the cracks because I don't communicate directly with the engineers. I'll give it a shot though.

Thanks Carl. That's probably the most important bit, as the oil quantity is usually critical. Measuring what comes out will always leave you a little short as lots of oil clings to internal surfaces, and even if you got it all out, a little paranoia could always creep in about wether the Chinese put the right amount in.
The dismantling procedure can be worked out.
I have tried to locate a workshop manual, but even the importers here in Spain say there isn't one available. I can't believe that.
I did get one for a Suzuki DR200SE but it has different conventional forks.

I can't understand why the maker of such a gorgeous component does not stamp his name on them somewhere, are they not proud of them?, I certainly would be. On top of that their price from the Spanish importer is only 200 Euros...(316.875 USD) which I find very reasonable. For the Zongshen 200GY version the price in the UK is only 111UKP, about 223USD.

Hi Forchetto! Just don`t forget the Genesis, KMF (Honduran) and Euromot (Chilean) brands of this model.
Jokes aside. I agree with you in regards of the beautiful machining involved in the construction of this forks. I should dare to advice that, if no official information is found, you should try the dismantling and measuring oil method, and if the action of the forks felt decent previous to disassembling them, and you only need to get some stiffer action (to help rebound), you could probably won`t go wrong with adding a little more oil than measured (providing the forks were not leaking before, of course), and also you could play with different viscosities and/or brands of fork oils. Aditionally, you probably add more preload to the springs with some teflon spacers. In the end, common sense should prevail.
Enjoy your ride.:riding:

Thanks for your reply. I suppose you're right. No oil has leaked out so the chances are that measuring what's inside and maybe adding a few cc for what is left clinging to the parts should do it.
As for the machining and finish, I'm still impressed, although today I saw a bike equipped with some ÖHNLINS USD forks and they were so beautiful I stood there for several minutes just looking at them with my jaw opened!.
Thanks also for the other alternative names this bike sells as. I have quite a collection now. See the list on this thread:

http://www.mychinamoto.com/forums/showthread.php?t=76

I do wish the Chinese importers stopped messing about calling the same bike completely different names and models. It only muddies the water and makes it difficult to unite information from forums, locate spares, etc. In the Chinese bike world you have to be a bit of a detective to find out just who makes your bike...
There are people that claim that the whole Chinese bike thing is "just like the Japs 40 years ago...blah, blah, blah". Not quite. A Honda CB72 or whatever, was just that all over the world. If you need spares for a restoration or repair just Google that and the bits or technical help comes from all over the world.

I truly believe that Chinese are capable of engineering astoundingly sublime things (The Great Wall) as well of technological marvels (the practical use of powder). The problem is, in my humble opinion, that they are still happy with making things in volume... just for profit, massification. There´s really no feeling of brand pride imbedded into them... with the very rare exceptions that confirms theories. When the times comes "les caerá el veinte" (as we say in Honduran Spanish), and they could (and I believe they will) rule the marketing world. Maybe it's due to their cultural idiosincracy at the moment. Or maybe we are wrong and it may be a very genious approach to marketing in our present times (?). But, same as you, I wish they should start to do things right now with a little more sense of Pride, not just merchandising. A popular joke here is that you could put any truly blasphemous word as a brand from a Chinese manufacturer if you buy enough containers to make the fabricators happy. Sad! Hope our rides don´t end up being lemons. We`re still happy with them, but...:confused1:

Good news folks!

The factory got back to me with the specs for the front for oil capacity.

330ml in each fork tube.
Oil type used is Shell #32-#46

Also got the specs for the pressure in the rear shock...and will post that in the questions to QingQi thread...

Thanks for that exploded drawing of the USD forks. My copy of the parts list only shows the forks fully assembled.

Which bolts do you need the torque figures for?

I find I use this simple chart which shows torque for different grades of steel, very useful:

I search for face values for:
1. еngine head
2. cylinder
3. cross-piece (fastening of the fork, траверса)
4. covers of the block еngine
5. axis of front wheels
6. axis of back wheel

Guys few days ago I finally found time to open front suspension. Good news is we have two springs. So both sides absolutely the same. Was nothing special to disassemble it. Major task was to replace oil. I fill with new Motul fork oil 10W. Well this viscosity just good for some one who ride into town and some offroad. Any one who not only ride but go to jump time to time on cross track need at least 15W. I'm planing to replace my oil again. And my choice 20W. I like to jump.

I am a big boy and my bike bottoms out quickly if I have to brake quickly with any kind of speed, so I am going to get in with a heavy 20 weight oil pretty soon. I will let you know how I go when I get around to it.

Don't forget you can also put spacers underneath the fork cap to tighten up the preload. You loose a bit of travel but it may be worth it and it's not hard to do if you're changing the oil anyway.

That is true CC, but I will see how the 20W oil goes this weekend. Adding spacers is a much simpler process than changing the fork oil, so if I am still having problems I will just throw some in later. :scooter:

Ok, so I put a 20 weight oil in my forks on the weekend. Did it the easy way, and just put the fork upright in a vice, loosened the fork nut, lifted it and poured in what I took out (+10%), which was only 175mL which surprised me. Maybe I didn't get it all out? I dunno, but it certainly seemed like I did.

Anyway, the improvement in handling with a stiffer front suspension is incredible. Not just for stopping either (which I can now do safely without bottoming out) but also for cornering and bumps. I am very happy with it . If you are a large westerner (like me) I can wholeheartedly suggest changing the fork oil. It will give you a much better ride, even for just around town and any idiot can do it (like me). :thumbsup:

The other thing I did while the bike was up on the stand was to turn around the kick stand kill-switch. I find this little device very annoying. Although I understand that is designed to prevent people riding off when the stand down, it is very useful to be able to start the bike up while it is still on its stand so it can warm up while you are gearing up and generally fit-farting around :goodtime:. If you ride off with the stand still down, well, then you're an idiot (like me). :riding:

I was going to remove the switch all together and join the wires together to keep the circuit closed constantly, but when I tried to get the plug out of the housing I stripped the head of one of the little screws (peice of sh*t!) making getting the plug out impossible. So, not wanting to give up, I simply replaced the switch backwards so now it doesn't engage with the stand down.

NOTE:

The first ride after removing the front wheel I lost my front anxle bolt. :confused1: When I put the axle nut back on, I can't remember if I tightened it up properly or not (I probably forgot :asshat:) but just have a look after you take it for a first ride. I have replaced the axle nut with a nylock nut and am using a standard washer and a spring washer. That baby is not going anywhere anymore:gun_bandana:.

The factory reckon the fork oil capacity is 330ml in each fork tube. I think you're supposed to "pump" the forks to expel the oil from the inside of the damping cylinder rather than just let it drain off.

You SHOULD be able to start and idle the engine with the stand down as long as the gearbox is in neutral or the clutch lever is pulled in if it's not. That's how mine is wired up.

Hmmm, I did pump it slowly. But no more was coming out. 330mL seems like a much more reasonable amount. Maybe I should've pumped for longer? Well, I am not too worried about, even with a half oil change the suspension has been greatly improved.
