Hi, what are those 2 plugs for on the left crankcase on a 2019 CRF125F?

Welcome to the site !!

I am not familiar with that model , but in looking at pics of it , I am guessing that most likely the small top one is to see and align the timing mark on the flywheel ,and the larger one is most likely to put a socket on the flywheel to turn it to align the upper marks for doing maintenance , like setting valve lash , etc.

Thank you JimDirt!
