I just got my wheels back on my moped, since I replaced the tires, I put the chains back on, went to start it, and snap! the master link broke on the one chain. Anyone know what size chain it is so I can find a new master link? It's the chain on the left side if you're sitting on it that goes behind the big pulley. The rest of it is fine, one of the pegs in the master link just sheared for some reason... Thanks in advance for any help!
