I've rode this motorcycle many many miles. No speedometer. No tach. No gauges. I know what the motor sounds like when everything is spot on. I inspected the plugs - I set the valves. Guess what? My breaker point gap had narrowed . . . .014. That changes your dwell (measurement in degrees my #2 cam rotates with the points open). Like a mother that knows when her baby is a little sick - I knew something was fishy in Denmark. I don't need a prescription for this one - all home remedy !
