Motorcycle Repair: Bike not starting/not fully charging, v45 sabre, regulator rectifier

Question
Hi there,

First of all, thank you for offering this service. Well, I have a 1982 Honda 750 V45 Sabre and have been having issues with it ever since I bought it a year ago. The issue is that the bike won't start own its own. In order to start it, I have to charge the battery up (it only charges to about 8 volts when the charger says its fully charged) but then the bike dies after about an hour of riding. And the cycle continues. I have had a new battery put into it, two new starters, starter solenoid and had the carburators cleaned. After all of this, I am still back to the same point (needless to say, I am a little frustrated with the recommendations from my mechanic). Anyways, the last time I had the bike out, the regulator/rectifier burned a hole in the bottom of my seat. I'm wondering if this could be the whole issue and should try and replace it. I would love to hear your input and any suggestions you might have.

Thanks,

Nick Walker";  

Answer
I usually only answer questions on harleys, but I might be able to help you.
First, you have a problem with the charging system and that is why the battery goes dead. As to what part of the system I am not going to be able to help you, as I only know harleys.
Second, if what your telling me is right, then I would not take my bike back to that mech. The 2 starters, starter solenoid and the carbs have nothing to do with the charging system.
Good luck and happy riding
Mike
