Broken Chain, Oil Everywhere

All my fun came to a screeching halt yesterday because of chain failure. Ya could be my fault, but to my defense, the chain and sprockets are in great condition. I also clean and lube every 3-500 miles. I'm putting the blame on the master link....

The good news is that a tire coated with oil didn't take you down. I understand that this can decrease traction considerably! Lots of dish soap and a brush should clean up the tire. Glad the damage was reasonably minor all things considered.

OM? What type of master link did you have on the chain: rivet or clip?

Clip.

I'm not hearing anything good about these. And my mechanic buddy who came over last night couldn't believe the bike had one. Not sure what the new chain is coming with, but I will get the rivet on or screw on ML to hopefully prevent this.

there's only one relevant data point here: you lived. An oiled rear tire? Yeeks. And you didn't even kill the motor? Dude - buy a lotto ticket: stat.

Did you recover the chain and check out the point of failure? Is it possible the tension was too tight causing accelerated wear?

Yes and we found part of the master link. The chain failed at the master link. The chain tension was with in spec.

Man, there are all kinds of ways that could have ended catastrophicly! Glad it was a relatively benign event. I'm scared of clip master links, only rivet for me.

Higher powered bikes should really use riveted links. It is pretty much like an endless chain.

Agreed. However, here's an instance where even a Rivet Master-Link failed.

PNWRiders.com - Chain issue this morning

Revisiting the thread, one of the possible explanations given was that the chain hadn't been properly riveted. Another possible explanation might have been it had too week of a chain (520 rather than the OEM Specified 530). No way to know for sure, but at the least I would recommend double checking the flare of the master link's rivets to ensure that the pins were properly set.

Was the ML clip facing the right direction? Been a untold miles put on lotsa bikes and industrial equipment with clip master links, most times failure due to clip facing wrong way or broken or deformed clip, always use new clip...but yeah proper rivets are good for big HP
