Maybe you got a leaky gasket... BUT where is it coming out at??? If you havent allready, get the entire motor spotless clean, then run it and see where it is coming from... it will help us get a better idea of whats going on....

What year is your YFZ??

The 04-05 models have a plastic plug to plug up the decompression hole that is used due to the design from the dirtbike motor.

just like what 2 fun said its that plug, i had the same problem with mine. vitos makes a metal one that holds up a lot better.
