What are the exact measurements of 49cc piston ring?

[daninthesand]

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.

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.

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 !!!)
