Hey guys, I was just wondering how much oil you guys put in you 07/08 wr450's. Whenever I put a whole quart in, the thing pisses out oil from the breather in the air box. ***. I have been using about 80% of a quart for a month now, but I don't know if that's right. Any help would be appreciated. 07/08's only though, the 06 and older have a different setup.
