What a real bummer mate. I know the feeling well. I also ride an '83 base K100. Love hate relationship, but that's another story.
Look, an old retired mechanic told me once that when you get these mystery problems, they used to begin with by checking the "FACTS". The "FACTS" being: Fuel, Air, Compression, Timing, Spark. Check everything related with these systems that you can, and you must find the problem. I know it sounds simplistic, but give it a go and you might be surprised.
