Since changing to synthetic oil, I have a large amount of oil leaking from the front/top of my engine. It is mostly spewing out the heat vents in the right lower fairing (RT), and some is pooling above the hall effect hatch and dribbling down the crank cover.
I removed the crank cover, timing chain cover and valve cover, and I removed and cleaned the gaskets and channels (both mechanically and with solvent) then siliconed them on each side of the gasket.
The sensor in the timing chain cover has an oil seal around the crank boss, but I noticed no oil inside there.
The oil is leaking at about a half a litre per 100km. Where could it be coming from?
