okay this is starting to make me wonder alittle bit, my '02 YZ 125 after riding it after its nice and warm and I stop the power vavle breather hose leaks a tiny bit of oil. It didn't do it from new but after I got like 30 hrs on the motor is when it started. I just put in a new top end in it and everything looked great. The power valve was nice and clean operated fine. The bike is jetted great and I just put in a new air fliter. I haven't ever over filled the crank case when changing the oil either. I'm just at a loss on why it does this after every ride when its nice and warm. It doesn't do it while i'm riding just after the bike hasn't been running for a few mins 3-5 mins. The amount of oil the comes out in very small, Am I just tripping and its normal as this is what its suppose to do? Its just got me wondering cause other owners of the same bike haven't had this happening.

This is normal on the YZ 125's. Funny thing is they have the hose so is leaks all over your frame sometimes :confused:
Don't worry though. My YZ does it. And my friends' YZ's do it too. Last weekend one of my buddies with an '02 first noticed it too... and was a little worried. But it's supposed to drip out a little bit to keep the oil from getting built up on the powervalves.
