Hello everyone, so I just bought a 1982 Honda CB 650, although I
overpaid a bit for it, due to my huge desire to have a bike to ride
this year... I ride it home, but on the way it starts dying.

I've been reading all about the electrical and charging issues these
old Honda's have. I've heard all sorts of replies. I started checking
what the problem is, I ordered the Haynes repair manual, which should
be hear soon, but in the meantime I want to know:

In this particular model, if everything is working good, if you
disconnect the battery while the bike is running, will the bike die or
not? On newer bikes it doesnt die, but i'm not sure for this model,
because mine definately dies immediately.

I checked the voltage yesterday while the bike is running, and
reving... 8 volts or so, I took off the stator cover and sprayed
electrical parts cleaner and used some high grit sanding paper to clean
off the stator/coils... now when i'm running the engine its at about
12. I know I need about 13-14v to successfully be charging the battery.

Any ideas? I mean... something changed. Possibly a loose connection
somewhere or high resistance somewhere? I am thinking of sodering
anything that looks suspect. What wires should I soder, which wires
shouldnt I?

And if it comes down to it, where would I buy stator/coils/etc for it,
aftermarket or OEM?

First off, if your battery is only giving 8 volts, then you definitely
have a problem.... how old it the battery? its its older than 2 or 3 yrs, I
would consider a new one... they are only about 35 bucks.....I would also
try charging the one that is on there first to see if it even holds a
charge..... your charging system might be good, but the battery may not be
holding a charge....if your bike reads around 13 volts while running, then
your battery should be good and then you can check it after you shut it
off..... if the voltage decreases while you are checking it, chances are the
battery is no good anymore.

Good luck
