    I need to replace broken piston rings for a Chinese built "50CC" 2 stroke. Mine are broken so its virtually impossible to measure them accurately. Can somebody please give me the measurement of theirs so i can send the specs to a piston ring place and have them match them up. thanks.

    The best I can do to measure is 42mm OD, 38mm ID, 2mm thick. but it is not exact since the ring is busted and hard to measure.

    THANKS EVERYONE.:jester:

    PS. Yes, vendor i purchased motor from would be the best solution but they have now and in the past been extremely slow in responding to e-mails.

    I have since been able to contact the vendor and have ordered new rings. But i'd still like to know if anyone has the dimensions.:D

    each factory will have different dimensions
    they may look alike, but that's where the similarities end :(

    Thats interesting...I assume then that each vendor would likely order their spare parts from the same manufacturer as their motors.

    or they rape bad/returned engines for parts (I have gotten parts that were obviously used !!!)
