Usflag rm 125 crank seals

i have a 1987 rm 125. it starts fine but is burning oil and running rough. i changed the crank seal on the clutch side and it didnt fix the problem. either i didnt do it right but i think i did, or the oil is getting into the chamber somewhere else. is the only other place the center case gasket? thanks for any advise offered.

The crank seal or the gasket - that's about it.

Keep an eye on your trans fluid level until you know for sure.

Cool rm 125 crank

i tried a pressure test but was not able to. the pressure kept leaking out the exhaust valve? i pulled the piston and the ring was damaged and some lite scoring on the wall. i am going to hone it and put a new ring and see what happens. thanks for your help.
