Gentlemen,
While checking the installation of a new Banshee-type flywheel (an XS Charge unit with a Woodruff key), I noticed that it had a noticeable amount of runout when the motor was turned over -- both axially and radially. Total movement is about 1-2 mm measured at the outer edge of the flywheel. I could also see that the gap between the flywheel & stator coils would vary as the crank rotated.
Nothing is touching or getting too close (as far as I could tell), but it made me wonder how much 'wobble' is permissible with these flywheels.
Will the wobble cause vibration?
Are the flywheels balanced?
Has anyone else noticed something similar?
The flywheel was carefully installed and torqued. (And fussed with & rechecked.)
The crank appears straight.
Any input would be welcome.
