Balancing and i5

[Darrell Boehler]

 Hi All,
    I am a newbe to the i5 look for balancing experience.  I recently had the moving parts on an MC engine dynamically balanced.   I
notice the shop took  quite a bit of weight off the pulley /vibration damper  on the flange side. The flange or tang is what a
special wrench would use to hold the crank from turning while removing or torqueing the pulley bolt.  Is it normal that a  balance
shop would remove a lot of weight in this area of the vibration damper.

Thanks
Darrell
