Hi Maux,
Sorry for the late reply, been away for more than a week now. Can't see your bike, image not attached properly. Upload to some hosting service like http://host.fotki.com/ and paste the link between [img] and [/img] tags.

I’ve had the Long March for a little less than a year now, approaching 10k now. I basically chose the bike believing that I’d have problems with any china bike. I might as well start somewhere and learn how to do my own repairs. You consider a big fat tank and the rack not to be deal makers, but I’ve had very hard time customizing anything in China. Once I called up some suppliers for aluminum pipe, and they said sure, how many tonnes do you need? Never heard from them when I said I just want 20 meters total. The basic DIY stuff you could find down at the local hardware store are more than difficult to get in China. But then again, your millage might vary; I haven’t toured all China yet!

Tank, racks and the WWII bike messenger basic looks were the deal maker for me. That, and also when I tried the Qingqi 200 Enduro, I found it to be tiny (I’m only 176 cm tall). I don’t know about the 250 Enduro. Till today, I’ve had a love-hate relationship with the bike. It takes me everywhere, runs for 16 hours a day no problem, but overall it’s much less of a bike than should be. Even if it’s just a 200cc. Small things that add up like the shift lever getting stuck going from 2nd to 3rd sometimes. I just have to push it back to 1st, then still with the clutch pulled in go back to 3rd. The seat doesn’t sit securely on the bike. It’s bolted on and relies only on the torque of two bolts to hold it from going back and forth. The rubber mounts that should reduce vibrations are getting torn off from the seat moving back and forth all the time. Seats on other bikes just click in, have just enough space. I had to change the seat as the stock padding was way too soft. Small things like that, I just need to know a few friendly mechanics or have my own tools to sort out. But really, I think all China bikes will have same problem.

After I changed the 56tooth rear sprocket to a 46tooth, bike doesn’t vibrate that much. RPM stays at ~5k cruising comfortably on the highway. But I haven’t compared with GPS yet. Also, I haven’t tried it off tarmac yet. But overall the bike feels much better already. Accelerates nicely out of traffic, speedo needle doesn’t wobble anymore, at least not too much. Still, for a bike from made in 2010 it should be smother that it is. But that doesn’t really bother me now. If I’m happy with cruising speed on the flat highway, and still have some low end torque for the trails, I’m more than happy with the bike as is.
No rust so far and it’s been in the rain a couple of times. But I always store it out of the rain. Seems paint quality and coating is good.
Planned Improvements:
• redo the wiring
• fit HID lights
• get better tires
• spark plug
• mirrors
• exhaust
