White goop coming from breather hose

2 posts in this topic

I own a 2000 YZF 426 that started to leak a white goo from the crank case breather hose. I know it is common to leak a few drops of oil, but this is more like 10+ drips. I have owned the bike for 3 years and never had this happen. The bike was in storage for about 4 months, but I did a full service on it before I rode it (change oil twice, radiator fluid, fork oil & seals ect..) It was cold the day I rode it, about 40 degs, and I don't know if cold weather would cause the oil to pick up moisture and turn white. Any help/avice would be great. Thanx!

Search for this topic. It has popped up a few times over the last few weeks. If your oil looks fine and your anti-freeze looks fine then it's condensation building up in your valve case. No big deal. It does it on my 07 YZ450F every once in a while.
