No problem. Bearings tend to whine before they fail and the bearings in the crankcase should be engineered to last for the lifetime of the bike. Unless someone did shoddy work on it or consistently beat the hell out of the engine by riding at redline, I wouldn't worry about the bearings.

The cylinders/rings are the more likely culprit. I would check it again next season and if you find the same amount of shiny bits, bring it to a professional for a diagnosis.
