Too much oil perhaps.
lol.. not that simple im afraid.. but thanks for the suggestion..
to be sure though, i drained all the oil and only replaced 2 qts.. still the same phenomenon..
clogged oil filter inlet?
checked that.. it was my first best guess after a bad separator..
Either that or just design...
Could plumb it to the road...
"plumb it to the road".. help me there, i dont understand..
as to design.. the oil seperator/reservior makes no sense.. the porous cast filter obstructs nothing.. in fact the path that the oil/oil vapor takes has no obstruction by design..
IMO, the vent to the airbox is breaking out of the wrong side of the reservior, (or the separator filter plate is designed onto the wrong side of the reservior) and doesnt even utilize the cast filter..
anyway.. back to the crankcase pressure issue..
ive been doing some more research and have read that rings are the most likely suspect in a high compression motor..
the articles mostly referenced large bore v-twins, or high compression single cylinder motors(quads)..
i cant find an easy way to determine that as a fact until i pull the top end.. i suppose compression testing could find a "lazy" cylinder, so ill start there.
ill keep adding as i find more, but suggestions are certainly welcome..
