SEMI CUSH : We filled the cush drive rubbers with silicone then swished the drive hub in and wiped off the over flow, for a semi- solid rear wheel with a little shock for the all.... broke a few RK630HD chains leaving at [ 9800-10,000 rpm, throw out the clutch on the two step ,red springs shimmed ] that went out the back and one that broke the shift shaft and case cover on ZIR. Speaking about baskets you do ding the fingers and make the disc stick in and out, de-burr finger, check tabs on disc weekly for Bracket ET bike.... on any PRO BIKE every pass.
