I am hoping one of you guys can help me out with my problem. I put a Daemon engine in a Schwinn DelMar. I am having a problem with the chain's master link. As it rolls over the tensioner, it is binding a bit and snaps as it goes over the roller. The master link stays together and is not coming apart. It appears to me that the master link is a hair too wide. I am using the stock 415 chain. Any suggestions?
