oil leak

[HaChayalBoded]

Hey guys, I had this bike (01 monster 620ie) for about 3 months. It was supposed to be for the woman but I ended up selling it to a friend. If it were physically larger I would have kept it for myself.

Anyway, my friend is telling me it has an oil leak. Even though I parked it in the same exact spot and put roughly 1k miles on it myself I never had the issue. The bike has about 12k on the clock.

Is there an inherent issue with this model, or is this a common issue and nothing to worry about? Every bike has it's quirks, I'm hoping this is just one of those.

Anyway, here are the pics.

I'd like to bet on that oil coming from the case breather valve, more specifically the washer/seal between it and the engine. It's easy enough to replace and cost very little.

It can be other things, but try that first...

Could be the breather, could be a cylinder base leak.  Clean the area thoroughly, go for a ride, inspect.  Still not sure?   Clean the area thoroughly again, dust with aerosol foot powder, go for a ride, inspect.  The stain in the foot powder will lead you to the source of the leak.

Ya know, the first few times I popped the tank on these bikes I thought to myself "man, what brain dead idiot designed this thing and couldn't even have some sort of prop for the tank" I would always use a bungee between the top latch and the rear cowl.

Then my friend send me that picture and I smack my head....there IS A PROP!!!
