You give no information regarding your Valkyrie"s age and miles, yet you seem determined to want to do something, so:
Had a Front wheel valve stem go bad on me and been wanting to change out the wheel bearings so thought this is a good time.
There is never a good time to R&R good bearings. Good bearings are good! they potentially will outlast the motorcycle!
Now you have a problem and started to "adjust".
I pulled the wheel off again and re-set the right bearing - which moved the wheel over about 1/8th inch an all seems well now.
I guess you just needed a bigger hammer!
To me it seemed the spacer between the bearings was too long and would not allow both bearings to be seated all the way to the stop in the hub. I installed the right side first, like the instructions say, and then the left and evidently when I seated the left it pushed the right out a bit.
That spacer is designed for that wheel and is not too long. If you measure the spacer, and then the distance between the bearing seats, ideally the measurements should match. The spacer will be a few thousandths longer, never shorter that the distance between the bearing seats.
Or does it sound like something is wrong here?
After all is done, now the question arises.
I suggest getting another set of bearings and hold onto them. No doubt you will be needing them in the future.
