I have a 1973 Honda ST90. I’m new to forums so I apologize if this is on the wrong thread. It only seems to be charging 4 volts to the 6 volt system. The bike was garage kept and only has 900 miles on it. The entire engine was rebuilt professionally and it ran good for about 2 days after that. With a freshly charged battery it fires right up first kick, and runs for a minute. Magneto/stator look good and no corrosion. What could it be? Wiring under the seat looks rough and is all electrical taped up so I’m not really sure. Thanks!
