Vintage BMW Motorcycle Owners

Thanks Bill.

I know that during the motorcycle production, this wheel was balanced.
The question is, today, after about 70 years, should I invest time and money and find someone who knows how to test and true it?

As part of the front main bearing assembly process, with its bearing cover/house, there is a provision that says it should be heated and then mounted on the crankshaft.
