I have a 1984 Hond Nighthawk 650. CB650SC. It was my dad's only new bike he ever purchased. He rode that thing all the time. I think it was his only get away from working his ass off most of his life to be sure I and my brother and sisters got what they needed. He gave it to me a few years back, wanted to take it to Cycles-R-Us in Medina and drop it off, and I would not let him! It's been in my garage for a few years now and I have tinkered with it from time to time. But, I have no knowledge of this thing! He stopped riding it when it died on him at my uncles house. Would not refire. I put the jumper cables to it and it fired right up. However, it will not stay running and has a miss. I have replaced the rectifier and the stator (with the new upgraded design) supposed to be a better one for that bike)and a coil pack. Still same issues . DOES anyone have knowledge of these issues with these bikes? I would love to make it streetable again. Truthfully I would love to return it to him so he could ride it again... Any help would be much appreciated.
