Anybody ever replace the winding in a generator rotor?

 I have a 1980 CB750C with an open-circuit in the generator rotor.
Before I go plunk down $160 for a rebuilt one, I was wondering if it's at
all feasable to rebuild one myself.
(I've got two, so even if I tear one up, I still have one for the
core-charge if I buy one.)
It looks like the hardest part would be getting it apart.  I found the 4
screws under the front surface, but I guess there's more holding it together
than that.
I hear it's supposed to end up around 4 Ohms.  If it's 18ga. wire, that'd be
about 700ft, which I'm guessing would be about 1000 turns, which could be
sealed with epoxy.
Thoughts anybody (yeah, I'm a cheapskate).

 
An eternally-broke acquaintance tried rewinding his Suzuki stator with
transformer wire he bought from Radio Shack.

Transformer wire is insulated with a reddish brown enamel that will
not survive immersion in hot engine oil.

Suzuki's supplier (Denso? Nippon Kogyo?) used some kind of wire that
was insulated with a green plastic when winding
their OEM stators...

 Would a stator typically be immersed in hot engine oil?  This one's outside
the seals & is dry.

Honda's did it that way on a *ton* of their bikes. The XR/XL from 75cc
up to 350cc for sure. I haven't looked at the later models but they are
probably the same. Lots of early ones too like the Trail 90, Monkey
bike, et cetera.

Probably already guessed this is why he remains eternally broke. Radio
Shack transformer wire is incredibly expensive and you can only get
maybe 30' per roll. I have some here but I don't feel like looking for
it to make sure of price and length.

It really isn't feasible to use Radio Shack transformer wire for
rewinding anything. While that is what it is labeled, I think it more
for winding RF chokes or low value inductors. i.e. 10" of wire wrapped
around a pencil kind of stuff. Really, give the guy a break and tell him
not to buy it for stators.

 I've known people who wound their own coils for building electric guitars,
so anything's possible...
