Any advice on what you did to fix the issue would be greatly appreciated. Im interested too in if you replaced the race. I just re-set mine back where it should be. Im waiting on the bearing and the retaining ring that seem to be so impossible to find anywhere.
I needed new fly wheels. When I realized the bearing race wasn't in the proper place on the shaft I pulled the engine and took it to a shop for machine work. The shop discovered that the shaft on the cam side was bent and it caused the bearing race to walk on the shaft.
I have an engine rebuild thread going here: https://www.hdforums.com/forum/evo-c...evo-build.html with more information. The engine is back in the bike but I don't have it running yet, other things keep coming up.

Thats horrible news. Good to know but horrible as far what this is going to cost now if thats my same issue.
I don't know why you couldn't check the flywheel assembly while it's still in the case, put a dial indicator on the snout and roll the engine over by hand to check the run out.
Of course, you'd still need some way of getting that bearing race returned to the correct position on the shaft if the flywheel is true.
If you do decide to check the runout I'd pull the primary down and check both sides.

I already pulled the whole engine out of the bike and split the cases so I have access to the primary side. I took a pipe the same size as the race and tapped it back to where it was supposed to be. I basically ordered everything I needed (gasket, new bearing, retaining ring, new gears that got chewed up..etc) to redo everything but if my pinion shaft is bent thats another issue.
You have done nothing to solve the issue of the bearing moving on the shaft, so don`t be surprised when it moves again...
I get that, trust me. I just put the race back to where it should be. Im still trouble shooting stuff to understand why it moved in the first place to Im going to check to see if the shaft is bent with an indicator dial when I have a chance.

The pinion shaft may not be bent but the flywheels might have shifted on the crankpin . Check the pinion shaft runout with a dial indicator.

I just checked the runout at the end of the pinion shaft and it was 0.018. Doesnt sound horrible to me but I have no idea what the shaft runout tolerances are supposed to be.
