I owned an '84 700 nighthawk s whose generator chain seperated @ 20k mi.while i was starting it up. Upon dissasembly of the engine I managed to retrieve the broken pieces of the chain from the oil pan. The 5 I think side plates had broken in their middles at the exact same spots and the irregular edges (side on view) were virtual cookie cutter matches. My brother is an expert heat treat engineer and it was his opinion that the uniform weakness indicated a failure in the heat treat hardening process used. A rock caught between the sprocket and chain could cause instant failure? I've never heard of that happening in 40 years of riding. If it was too tight, enough to cause failure, the chain would make an obvious audible whine and vibration especially when coasting to a stop. I would ask for the broken chain and get it tested by a heat treat company for service spec. Their denial of defect is bogus lacking irrefutable hard evidence, else we're all in imminent danger every time we twist the throttle on this rather powerful machine.
