BikerT - at least based on your reported data suggests the stator & R/R both look normal
- per the findings of EnglishYankee, another problem that also often manifests itself is of the interconnects;
so important that both the 3 -way stator connector and the mult-pin input/output connector of the R/R are in good condition, with no sign of any corrosion or arcing/burning damage.
Having one of the stator connector terminals (at either interface) being bad, has the exact same effect as there being one of the three stator windings, or legs of the R/R being dead.
English Yankee - when bike is started & running, what does the battery voltage measure at both idle and say 4k rpm?
One quick ps on re-terminating wires into new connector if it becomes necessary: the stator wires can all be interchanged with no consequence; it is immaterial that they be matched to original connector location.
Also, be sure that these connections are stellar - ideally a high-quality crimp. I usually crimp my terminals and then ALSO solder them.
