Any differences in 79-83 stator?

    Thanks grimly, I'll double check next time i'm out there. I sense a little sarcasm there Tom, My father in law likes to pudder around and look at every possible problem. That's why we did the magnets comparison. Hope I don't upset anyone. Worked on a outboard last year that wasn't throwing a ignition break to the coil because the pick up magnet went bad. So he is always suspicious of that stuff..
    Great help everyone Thank you.
    Conclusion, I got the right stator . It's just a bad one

      Hmm... not unknown for older magnets to go bad, but that was pretty much a real old bike thing. I encountered it on various BSAs, Nortons, etc. Never had it yet on a Japanese bike, but I think I've heard about it on one or two of the smaller, older Suzukis / Hondas. I'm not too certain of the composition of Japanese magnets, but they're pretty good for non-rare earth.
      http://en.wikipedia.org/wiki/Neodymium_magnet which has the inception of them as 1982.

        We put a low voltage through the stator to recharge the magnets just to see if the would be a difference. We then got 25v instead of 20v at 5000rpm still not what we need but it was better.

Voltage coming from regulator is good, disconnected it goes upto 14v until 3500 rpm then drops radically, hooked up to the battery (brand new) we can barely get 12.5v when we rev it up. We took apart a couple other engines we have lying around and did a comparison Between the magnets . The suzuki one seemed a little weaker Compared to the Honda rotor.
          I have on more than one occasion fixed that by adding grounds. Not always though.

            Back to the magnets, the gaps between the magnets are inconsistent. Two magnet are pushed together almost touching. The other gaps are wider. I'm talking about the position of the magnets in the rotor. Is this normal? Sorry for beating this dead horse. Just like to confirm its stator before I go buy another new one.
