[NO SLO PK]

Zero balance is preffered. But the balance on the flywheel and balancer have to match balance on the crank/rods/pistons. They all have to be 50 oz. Or they can all be 28 oz., or 0 oz.

If you have stock crank/rods/pistons, then your balance is 50 oz. You should add the corresponding weight to the flywheel.

I'm not certain about adding weights up (?)
