One more thing to check is the connection of the yellow wires from the alternator to the rectifier/regulator.  3 yellow wires.  If it goes through a connector, check the connections for corrosion or rust.  If the corrosion is not too bad, clean them well with contact cleaner and put on some dielectric coating before connecting them back up.  If they are very badly corroded, then one option is to clip the wires going to both ends of the connectors, and solder them together.  I did this on my Shadow, and the charging system worked MUCH better after that.  You can look around on other threads for Honda and similar motorcycles: just search for "3 yellow wires".
