I just picked up and 03 WR 450. I traded my 08YZ 450 for it. It's Plated for The road and it's been good so far, anyway I came to work and noticed that down on the back of the crate c anyway I came to work and noticed that down on the back of the crank case I had oil leaking. Some Of my suspected areas are The crank case gasket (because it' seems to be seeping out of it), the oil drain plug (because the oil runs undrrneath), the counter shaft oil seal, or possibly oil just blowing out of valve cover breather. I cleaned oil up good 2x. Can't track it. The second time I pulled the breather hose and moved it to the front of the frame with a zip tie. But it's still getting wet on the back side of the crank. If any of this makes sense to anyone and knows something let me know. Thanks !
