OK, that dog ain't gonna hunt too well.
All KLRs, 1985 to 2018, have a three-phase alternator. The stators are wound in an 18-coil format with three sets of six coils (there are phantom coils '85 to '07 where the two exciter coils are, but electrically it is built as if the three missing coils were there). Those three sets are, electrically, offset by 120 degrees. Thus the 'three-phase alternator'. They are wound with a "Y" configuration with the three wires coming out and going to the rectifier/regulator.
What does all of that mean to you?
You have an '84, which was the only KLR that was kick-start only and the only KLR that was built with a single-phase alternator. It is built as a 12-coil stator with all 12 coils wound in series, thus it only has two wires to go to the rectifier/regulator.
I think you can make it work by installing a three-phase regulator/rectifier. The 21066-1038 that was used '85 to '07 is an OK unit.
The '84 rotor is unique also, so there's no way you can swap in a later rotor and have it work. However, it has 12 magnetic poles just as you would expect ti to. Magically and mystically, the later rotors also seem to have 12 poles (though my impoverished education would have led me to believe that an 18 coil three-phase alternator would need 6 poles) so I think that the '84 rotor will work with a three-phase stator.
That's two "I thinks" coming from a guy who prefers "I know" or at least "I'm pretty damn sure", so you'll have to try it to find out. I'm going to be trying it soon.
