Hey guys I'm new here. Hopefully this is posted in the correct place. While riding yesterday I was crusing a long in second gear, and shot the gas to it, when I did the drive chain broke and binded up in the front sprocket, breaking the chain gaurd in the process. I put a new chain on it, and now while I'm in second gear and hitting the gas, there is a clanking/chattering sound, but only when hitting the gas and only in second gear. My questions are what could have caused a brand new chain to break like that, and did the chain breaking cause the noise I'm hearing now? Or did something breaking internally causing the chain to break. Any ideas on what the noise I'm hearing now is would be very helpful. Thanks in advance.

I'm guessing something in the trans broke causing the chain to bind and break. I would tear it down and take a look.
