Oil leak F4R 2014

Hi,

Hade a pretty hard session at the track yesterday and when the 3 session was finished i noticed a had oilslash on my right lower faring. We did some quick checks and it seems it is oil from my rearbrake master cylinder as it lays a pool of oil on top of where ths hose gets conencted to the cylinder. If i wipe it of and drive again it is back when i stop.

Where should i begin my troubbleshoot? I have limited mechanical skills at most

Clean and dry the entire area with some commercial aerosol brake clean. Get some unscented foot powder spray that dries to a white film (Desenex??) and spray a film around where you suspect the leak is. Look for a dark stain to appear where the leak is.

A better spray powder is this: http://www.penntoolco.com/crown-1073...waAq0PEALw_wcB

Start the bike to warm the area if needed. Or pump the brakes if you think it is brake fluid.

Is it common to leak oil at the mastercylinder?

It would be impossible to leak OIL at the rear brake master cylinder...

It could leak Brake Fluid, but that is also rare.

Do what Ed said.

Found it. It's the engine that is leaking. It is a small leak and only appears when its really hot. Will take it to the dealer.
