Hello I have a 2002 v star 650 that is leaking oil out the final drive breather vent, can anyone tell me why? I filled it to bottom of threads like it says to do.
Is it cold weather where you are? When it is cold, the oil can froth as it heats up and leak out the breather, it is why its there. Do you have synthetic oil in there? It is less prone to that problem. I use Motormaster 75w-90 synthetic gear oil in mine and don't have any issues.
