If the starter motor is spinning then it works!
possible slipping clutch mechanism on the back the of the rotor

Well I took the side cover off and found the flywheel is spinning free and will catch sometimes. I'm guessing it's the woodruff key. The flywheel spinning is what I was hearing.
That is a good call. The 03 WR was noted for having a woodruff key defect. I believe there was a recall on that when the bike was new. Not sure if you can collect on it. They fixed the problem on the 04 and beyond.

I was just going to add something, but I think you figured it out
I had a harley sportster that had a steel ring gear pressed onto the aluminum stator
The press fitted gear was slipping and not turning the engine over
drove me crazy !!!
Sounds like you have something similar
