My 850 MKII has a good amount of oil leaking happening left side down around rear side of primary case. However I'm not convinced it's chain case oil (I'm using same as engine oil at this point) getting out the rubber perimeter seal. Checking carefully with a mirror and lamp laying down beside bike on CS, I can follow the oil path from header pipe bottom side, drops along chain case seam, to a little river running vertically down from the front sprocket drive chain casing flange. Chain is putting up a lot of fling and looks a bit wet after riding...the stock chain oil was disabled by DPO...yet I also see the remains of that system, up high in front of rear mud guard. the felt containing tube with associated clamps, appears quite wet with oil....so could that be the ultimate source here?
