Just wondering what the life is of the updated chopper bearings. Has anybody here had them fail? We have 3 8240's with 1200 sep hours that have the updated bearings and have not have any problems yet. We've been greasing them at least every 80 to 100 hours. Debating if we should change them before they cause problems. I believe a kit with all 3 bearings runs around 500 from our local dealer.
