we own a 1971 honda cb100 and it is original that mom and dad bought it new - we have a problem right now and the bike will start however while running if you turn on the lights they work, but the turn signals won´t blink.l Wehn you turn off the lights the turn signals will work, however when you do all that you run down battery and it dies. We think it is the magneto would like to know if anyone else has had this issue.
