Okay, displacement is governed by cylinder size which has no gyroscopic effect that I know of. I always thought that the crank and fly wheel were the main gyro culprits. Theoretically, a 600 or a 1000 "could" have the same sized crank couldn't they? 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.
