Having touble getting my bike to move forwards
Ola,
I suspect there may be some problem with my bike that I haven't found yet. Bit of background first, this is a Zongshen 200 gy-2, about 8 or 9 months old +- 30 000 km's on it and has never been crashed, services regularly etc etc. The bike starts "fine" tough does sound a bit off, slightly rough earthy sound if that makes any sense. now the real problems starts when I try to disengage the clutch and move forwards... I get a horrid grinding sound and the bike just shudders without moving at all. I recently had the bike services due to some electrical problems and just cant figure out what the problem might be. Have attached some photos in the hope that one of you might be able to stop a problem lol what happened is that the bike was having various electrics and stuff fixed as well as having the head gasket replaced due to an oil leak, in order to replace the gasket they had to take the engine out of the frame. As soon as they unbolted the engine form the frame it fell apart. Looking at the rust on the break itself I am guessing it happened months back and the engine basically held the bike together. moral of the story, Chinese bike are most likely worthless :o Just glad I wasn't riding the thing when it fell apart, or even worse my girlfriend. Tis still under warranty, for like 2 weeks!!! rofl so I get a new frame D |

YEP, thats what I would call a catastrophic failure.
That gives me even more reason to try and close the frames up on ours. (they just got to last long enough for operation DRZ400s & TW200) I wonder, did you ever have to replace to engine mounting bolts or were they all sized correctly from the start. On our bikes the engine mounting bolts were smaller to adjust for the lousy fit of the engine to frame.This allowed the engines to move around and shear off the bolts and lossen the chain. I wonder if ours has any metal fatigue at that point in the frame? |

Was this bike ever "jumped"? I can't imagine this happening with "normal" riding....but then too they are made in China.

Maybe two up? I'm searching for excuses...I do know that this is round tubing whereas the backbone on mine is rectangular. I sure hope I don't get surprised one day.

Its obviously due to lack of maintenace and operator error.

(still looks like operator error) |

ok lets explore that option for a second. How would I weighting in at 75 kg's manage to place enough stress on the frame without lets say damaging the shocks, the bolts mounting the engine, the rims, the spokes, the handle bars......... :?: |

30,000kms in 8 or 9 months, In South Africa could do it. I dont even have 30k on my 1980 Kawi..

That's from excessive stress. Rust would have thinned the tube out. The one picture/angle that would make it obvious is the one that's blurry.
Probably done on purpose. |

I'm so glad ours arn't made like that other one.
(wifes bike) Not that this design will be any better but if I close the frame in it should help. plus we arn't as likely to have operator error either |

Most of the Japanses DS bikes I've seen don't have 30K on them, let alone that kind of mileage in less than a year.
If you want to crap on your bike , fill your boots, but to crap on Chinese bikes in general on this site because you had a bad experience is not recommended. Despite all the issues I've seen in this forum with respect to Chinese bikes I've never seen a a broken frame tube. It's an anomaly to say the least. Do I think you abused the bike? Probably not, other things would've probably broken first (rear subframe, suspension, rims, etc....). That's a thick piece of frame tubing. Let's keep it civil. To me this is a manufacturing defect.
