Have some oil mist coming from breather filters, just wondering what some causes are or if this is possibly normal, to a degree.

 

Make, model, miles(KM's)??

 

120 Ultima, Evo style. 600 km but just finished the rear cylinder top end, but mist coming from both vents. I was concerned about rings but I would think anything in the combustion chamber is being burned.......

 

Your crankcase "breathers" can mist some. Unseated rings can produce crankcase pressure along with too high oil level. Before doing anything, I would remove 1/2 qt from crankcase and try it. I do not know where the Evo's vent, but you can vent down and out the bottom of the bike or into a catch can.
