I'm short circuiting here. When you do an oil change ('07 WR450) and get the level right where it needs to be on the plug's level mark how come when you then remove the oil check bolt to drain off any small excess it drains, and drains, and drains, and drains, etc..... I can understand a small amount of drainage to level off but I'm talking about a lot. If I drain the excess until it stops coming out then, if there's anything left in the crackcase, it wouldn't even show up on the plug mark. What's going on here?
