I have a 139FMB engine in my bike - trivially google'able, and despite different variations I'm pretty sure it shares the same oil for transmission and main unit. I've noticed the bottom of the engine is pretty much dripping with oil after I ride; leaving small patches below my motorbike.
Now, the obvious thing to do is to check the oil level, but that's on maximum. I am not sure if I did put too much of it; the differing manuals said something between 700 and 900ml and I put in 900.
The oil down there is pretty much the same as the engine oil, it's not thicker like the transmission fluid (but it's certainly on transmission side).
So, how do I diagnose the imminent danger of that?
