I recently did the swap as well. Zero indications that the aluminum flywheel was about to fail. But I was having shifting issues which I'm nearly certain was due to clutch drag. FWIW, after swapping out the gear selector springs, new gear box oil, bleeding the clutch lever, and putting in the RAM clutch replacement, the bike has never shifted better or smoother. Worth it for that, and peace of mind that I was no longer sitting on a time bomb.
