250-500cc WR250 - oil from the power valve cover

Hi All,

Brand new here. I've got a 2008 WR250 with 19 hours on it (honestly, it's factory fresh) but when I gave it a short run (tarmac just to warm it up) I notice a small drop oil seeping from bottom right of the power valve cover. I wondered if the gasket has perished with age or lack of use, or is this nothing to worry about?.

Many thanks

Myles

I'd pop it off and give the power valve assembly a quick clean. Then seal it up with an rtv sealant. Or a new gasket gasket if u wish.

Thanks, I will give that go. Having come from 4t s the sight of oil worries me but less so with 2t!

Don't worry about it they all do it. Just make sure its tight.

Thanks for the info guys.. It' good to know it's not damaging anything. I’ve read about air leaks but I guess that’s anything before the air and fuel has gone into the cylinder, rather than waste out the other side.

The 125s have drain hoses.

The 250/300 just leak it out there....

I find if I use Amsoil dominator the spooge is reduced.

Also low speed running makes more spooge.

Being new to 2-strokes I was pretty freaked out by spooge. I use Goo Gone citrus cleaner. It takes spooge off with a paper towel really easily. Soap and water just smears it around. I'm careful not to get it on the o-ring chain or near the brake rotors because its pretty strong stuff.

Thanks for all the ideas guys - great forum!
