Default Re: Vibration - what is normal?

By adding or subtracting weight to the crank assembly you can move the peak vibration frequency around but you can't get rid of it without redesigning the engine.
Remember, the amount of vibration is inversely proportional to the rigidity of the mounts.
If you had a 10000 lb. model A with rigid motor mounts, you probably would not feel any vibration.
