At home flywheel balance....

If my math is right, at 70mph, your tires are rotating in the neighborhood of 800 rpm.

Your flywheel balance is a little more critical than that given that it can turn upwards of 6-7k.

Think: tire is balanced to 1/4 ounce increments that aren't even spec'd by moment.
the flywheel is hopefully balanced a little better than that!

To balance something is easy. To reach a specific imbalance is a little more difficult.

And those bearings are WAY too stiff for balancing. Just take it to a shop, unless you're planning on balancing stuff for a living.

OK, tell me... how much resistance do you think that bearing will have? and how much affect will it have on the balance?
How much weight do you think I would need to place on the flywheel if it was neutral to make it move to a different location?
How accurate is the factory balance.?

If you going to question what I'm doing ,then you need to have some numbers or data to back that up.
You also missed the part in my previous post that's says the wheels will be checked on a electronic balancer when finished.
