Your right, it won't be going anywhere. What happens is that the stretch bolt already being stretched moves a hair. This causes the crank pulley to spin out of balance and....YIKES. Think of it this way. When you get our tires done, they put small pieces to balance out the wheel under 1600 rpm. Now, a little out of balance on something that is spinning at 6000 rpm.....not good.
