That would mean the crank is heavier and theoretically less performance IMO they need the weight's to perfectly balance a more highly modified crank with bigger bores and turbo scope
If I am allow to open the backplate and pick engines, I surely will pick the one with none or less weight on the crank!
thats what their websites are for you can do all the comparison in front of the computer
But thats only if they keep the correct info on there
f you are getting an engine with a balanced crank (most likely mod engine). Less or none balance weight are always the better cranks. It means it is natrually balanced!
or not perfectly balanced just close enough
