Can I ask why this would happen? I was shocked I could spin the outer race with my finger with no effort and pop it out by hand. To see two hubs, one with only 16K on it and the other with 40K with exactly the same bearing issue leads me to believe this may be more common then not? If it does solve the issue then I think you're going to see a lot of hub bearing swaps on here in the next few months. I think I could do one with my eyes closed now, I've had this primary off so many times.

IMO I think this was your issue , but there is no garuntee of course. I've witnessed clutch hub cause some weird vibes that you would never suspect would come from the hub/bearing. Like I said in post #10 at the begining of this thread I had a feeling it was clutch hub bearing related. Again this might not have cured your vibration , but it was definitely an issue that needed to be fixed. I am pulling for a positive cure here though.
I wish I could find a better explaination of why this happens or one that seems a little accurate. Steel vs Aluminum at the bearing bore of the outer hub , steel inner hub shaft pressed into steel bearing with a tighter tolerance , the fiber plates locking in the outer hub , steel plates locking in the inner hub (the two clamping it all together), and somewhat of a "side load" is all I can think of. I haven't saw it that often on stock bikes, and I'm pretty sure it has happen on mine because I beat the **** ot of it haha.

You could probably cross a bearing over with a larger OD. I think the problem of steel in aluminum is more of the culprit IMO though.
I want to machine a "tight clearance" fit steel sleeve with a stepped face that can be locked via set screw/? to keep it from spinning in the bore. This will not only eliminate the steel aluminum contact , but allow for a tighter tolerance for the "press fit" around the OD of the bearing. I have an extra pre 98 outer hub set back for this project , but haven't been able to locate this "extra time" thing people speak of.
Hell my FXR has gone through a complete front to back, top to bottom, inside and out rebuild. All I'm lacking is wiring but can't seem the time to complete it with my work schedule. Maybe one day ha.

Not fixed. Just took it for a ride. I give up. Thanks to everyone who helped out anyways. Maybe I'll be back when I save up enough to cut my losses here and buy something that isn't broke.
