Hey there, just bought a sweet Heritage,1992 and she was woking fine then ran like crap, missing back firing,, swapped the nose cone sensor, nothing, new coil from another bike, nothing,, put in new ignition module and she runs like a dream. Start it the next morning, she runs for 5 minutes or so warming up and it just slows down and stops. Will not start,, turns over and then one big bang. Downloaded the manual and did all the testing they list and everything is good.
Question, do nosecone sensors, new ones, just up and die or am I missing something. I did find some bad connections on the white wires at the coil and fixed them, and the meter confirms no more grounding in the harness wires.
I'm freakin' stumped and could use some input.

Thanks

Doug
