I have a 1977 R100S that won't start. The starter cranks strong, but the motor won't start. not even a hint of starting. She started right up after I installed the battery the other day. I cleaned the bike, went to go for a ride yesterday. She started fine, ran about a half minute then stalled. I tried to start again and she made popping noise, now nothing. Just cranks and cranks. I had a reputable shop install an electronic ignition last fall, but the bike started and ran fine until put away for the winter. I'm stumped.Any ideas here?
