    I need a set of RINGS. The guy I called, says, they are backordered.

    Anyone know if rings from a different bike would work? does the cb250 means it's a replica of the Honda CB250?

    Thanks.

    Do you mean this engine (they call it CB250-G). If so it has nothing to do with any Honda CB250 model as far as I know:

    Jincheng Monkey JC50Q-7
    Skyteam Dax replica ST110-6
    Zongshen ZS125-43
    Qingqi QM200GY-BA Super Motard
    Qingqi QM110GY

    Not sure if we have a complete service manual for your engine round these parts, but off the top of my head and according to the QingQi200 manual, bikes in this size/class range use about 30Nm or (22fty/lbs) of torque for those 4 head bolts.

    If you snugged it to 25ft/lbs it probably wouldn't destroy the engine.

    Well, seems the company I found the rings from, actually make their own piston also for that engine and the rings aren't a good fit.

    Anyone know where I can get OEM rings for the zongshen?

    Thanks.

    You may want to try ZongShen America.

    http://www.zongshenamerica.com/

    I seem to recall other people calling them regarding a Sierra 200 and getting a live person but that was a while back.

    If they can't sell you the parts directly, maybe they can give you a reference to someone who can.
