Hello!

I have checked both vent tubes and the one of the right side (the nipple that points upwards) was completely clogged, so clogged that when I was cleaning it broke in half... I have bought a new one and I will test the bike but I hope that with that vent nipple unclogged and a new gasket the bike will stop ruining my shoes

As far as I have seen, at least in my engine model (ec250 2001) the left side vent is only for gearbox oil, and the right side one is for the powervalve so I think that the black spooge of the left side powervalve cover does not get out.

So thanks for your help!

The right side nipple is for the transmission vent. Left power valve vent.
Be aware that the two nipples have different orfice sizes.
Bigger orfice one is for the trans vent.

Hello, I had checked in the 2003 gas gas partlist pdf and both nipples had the same code "ME25710012", when it arrived to home I saw that the vent hole of the nipple is much more tinny that the one that the bike had, before mounting it I will probably make the hole bigger with a drill.

If something goes wrong I have 2 units.

Thanks for your info!
