@nottsbiker its not totally wrecked, has some pitting where the thrust washers are and some slight pitting on the stator side where the seal is, been running fine like that for 18 months, just wouldnt mind a new one next time i rebuild it
Engines back in the day didn't use to have balancer shafts.
Obviously it's going to have a dramatic effect on bearing life and, since there are no rubber engine mounts, a dramatic increase in vibrations through the handle bars. It becomes quite unbearable after a short amount of time.
I would say there are better things you could do to increase performance of the engine over removing the balancer shafter, like lightening the flywheel.
