Good idea Rob, the weight you save on the cam gear...
oughtta make up for the the covers and mounts you'll be adding! HA!
(Granted one is an inertia item... and I dunno how much impact yur gonna feel in the seat of your pants... but you alone might know, and that's what counts! Right?)

Seriously... I dunno if you know or have done this... but having 3 - 4 pounds shaved off the flywheel and then rebalanced IS SOMETHING you can see, feel and hear!
