Do not disregard the possibility of loose flywheel bolts (slightly,not very).This happens often when someone has left out the dowel when reinstalling the flywheel and crank grinders love to lose the dowel so it is forgotten on reassembly.
Get a bar on the flywheel rim and test for slack in the FW/crank/balancer assembly.
Or just wait---like pregnancy it will show itself clearly in time.
