WTF is wrong with these “certified mechanics” I have had these motors apart many times. Can someone show me a plastic bearing cage in a Ducati engine besides the small gear roller assemblies which are way too small to produce the plastic pieces shown in any of these photos. Also if one of the small gear cages breaks, you will have the rollers clinging to the magnet.
I have found in my Ducati travels that probably 90% of certified Ducati mechanics have never done a V2 or V4 tear down which accounts for the continued stream of dog .... information they hand out to their customers. Look at the very first post in the thread “the tech said ceramic bearings and cages in the crank and gearbox”. That clown has never seen the inside of a Ducati motor.
