I'm having a problem finding the problem to why my battery wont charge in my bike. The bike idles and runs but the battery wont charge. If I charge the battery in the bike with a battery charger and start the bike and ride to work few times the bike wont start cause a dead battery. I had to push start it to get it running a few times. If I have a volt meter on the battery and the bike running there is no charge.

Hey, repairing charging problems is just part of the fun of owning a DOHC Honda. If you just use the search feature at the top right corner of the home page here, you will bring up a few hundred posts on trouble shooting, and repairing the DOHC charging system. However I will bet dollars to doughnuts that the rotor is bad.

I like vintage bikes because they take me away from the clutter of technology that I work with everyday and back to a simpler time of mechanical elegance and simplicity.. "ninadm"

Check the resistance across the rings on the rotor. It should be between 4-6 ohms. Vibration wears the insulation off the windings and shorts them out. A nasty side effect is that they usually take the regulator out when they go.
