This is what the oil coming out of my catch bottle from the crankcase ventilation:
My bike have always consumed a little oil like half a liter between oil changes.
But this winter while the carbs were apart it was some sticky gunk in it so wanted to see what the crankcase spit out hence the catch bottle.
Since the balance shaft seal
is easy to replace I wanted to do that before digging deeper.
From the ride home (20 km) it looks good no sign of anything in the catch bottle but want some more riding before I call it a success.
EDIT: might add that I see no signs of water in the oil like any milky stuff on the clear clutch cover or flickering oil light and water pump was recently replaced.
