Some people want the extra hp, so there are companies that make a kit to delete the balance shaft.
Yeah the whole assembly weighs in at around 20 lbs. The shafts themselves aren't that much and it only really frees up around 3-5 hp maybe. What it is really good for is freeing up rotational drag and allows the motor to respond faster.
