installing 883 I have 440source flywheel question

All 360's are externally ballanced. You will need to either add a bolt on weight or remove material to achieve the correct ballance factor.

werent the cast crank 440's external balance? they might have been internal i just remember the cast crank 440's have a different balance than the steel crank.

did it say what balance the flywheel was when you bought it?
