I have restored a 70 Bonny. Installed a Boyer MK3 ignition. 6 volt coils. Everything seemsto be wired properly. Problem is that after running about 100 miles the bike starts to run like crap. Battery seems to lose charge. Checked charging system and all looks good. Putting out 14.5 volts +. After sitting for a while the battery drops voltage. I have checked and rechecked the wiring and nothing is miswired.Battery is new. The only thing that was not new on the bike is the stator. Would a new high output stator solve the problem. Am putting it away for the winter now and want to ride this thing as trouble free as is possible next year.
