Hey Gene...I had the same problem when I first got my bike. I replaced the battery with one from the Honda shop and that was all I needed. I'm sure that for those who ride mostly in town where the charging system is not operating enough would also need the regulator/rectifier too. It's a good idea and a good investment (if you have enough scheckles). How much was the one that you bought?
