Identifying TC Sprocket shaft bearing

[alakso]

Mike, you said I should have the SE black lefty sprocket shaft bearing already installed from the MoCo on my bike.

Is there a way I can find out from the Moco if this is the case?

Is there a VIN number from when they started installing the black lefty bearing upgrade?

If not would I be able to indentifying the sprocket shaft bearing I have in my bike by pulling off the primary, rotor, and sprocket shaft seal?

It's really important to know so I can figure out how much HP/TQ I can build into my motor without doing the bottom end.

Looking at a case here, it appears that you can see enough of the bearing outside race to identify as black vs natural steel on earlier versions (with seal and spacer removed) The new bearing will have a black "anodized" color outer casing. Be sure not to confuse the outer casing with the roller seperator. Other method is to contact your dealar (where originally purchased) and ask if they can call h-d to confirm.
