My son has been trying to get his 1962 (yes that's right 1962 personally imported) Honda 90 to run but to no avail. He has replaced points, plug, condenser, coil. He has checked all the wires for breaks. The bike ran last year but quit after tooling around a few times, maybe a total run time of a couple of hours. He was running it without a battery, could that cause component failure? Maybe be rectifier failure? Some forums say these older models ran fine without a battery but I'm beginning to wonder if this thinking is correct.
