Broken piston ring.

Thanks all for the help in the previous post. Here is something interesting..
Anyway the $40.00 Spree ran well. So I put in a new battery and rode the bike around the yard and in the street. The max speed was about 25 mph however it had trouble going up a slight incline. The speed would drop to zero!.
I read up on the tech stuff and decided to decarbonizes the exhaust.. sure enough it was more or less plugged. I put the exhaust in the barbeque and stoked up the coals. 14 hours later the exhaust crap was burned out.
I also cleaned the exhaust port.. being very careful not to nick the piston. Gave the carb a quick clean. And put the bike back together. Awesome performance the bike ran like new.!
The next day the bike wouldn├óÔé¼Ôäót start. I checked the compression and it was only pumping 30PSI. Off came the engine and I pulled the head and cylinder to check the rings.. sure enough the second ring was broken. Very odd.
I ordered up a ring and gasket set the bike should be running within a week.
Any theories as to why the ring broke?
