Also, don't engine designers purposefully install larger than necessary fly wheels to produce a desired effect which would increase the gyroscopic effect, right? I always thought that race engine builders typically "lightened the crank" to reduce gyro effect and increase hp. I'm not sure, you seem to be the resident expert. Oh and don't discuss "gyro" effect around all these new V-Twin-aphiliacs around here.

Technically a 600 and 1000 could have a crank with the same weight and throws, but then the motor on the 1000 would have to be wider to accomodate the bigger bores needed to make up for the extra displacement.
