Took the head off the bike and can't tell what is causing the oil consumption.

Have a look at these pics and tell me if you see anything wrong.


Cylinder looks great:



Compression ring looks good:



Oil ring looks good:



Do these valve stem seals look properly seated? Not sure about this one?
Intake side valves:



Exhaust side valves:



It's definitely burning oil, lots of buildup on the piston and the face of the valves.





The back side of the intake valves looks pretty gunked up leading me to thing the intake side valve stem seals are leaking?
