Now when you keep refering to power loss do you mean actual power loss or do you mean it simply revs up to where you want slower?

Once your up to full revs do you feel you still have lost power or did it simply take you longer to get to full revs?


My limited knowledge of engine physics would lead me to think the crank pulley would rev slower initially due to the extra mass but once up to higher revs the extra mass would tend to keep the it spinning easier and smoother.
