No, it is not common, but not serious. Oil is getting past the rings. If it still runs good and has decent compression, it is a cheap and easy fix. Just a new set of rings and a quick cylinder hone should solve the problem. If the bike has not run for a long time, an oil change and some miles may reduce the issue.
