Where on the engine? The head? If so, then you probably have blown a gasket..

its not on the head. its looks like oil is getting on the swingarm and the back of the engine. in the red box area on the picture http://img111.imageshack.us/img111/6/engineiw7.th.jpg (http://img111.imageshack.us/my.php?image=engineiw7.jpg)

Oil could be leaking because of a lose bolt, try tightening up some bolts, maybe.

ok thanks. i forgot to mention its blowing oil out of the crankcase breather tube.

does it have any type of pcv valve? a non functioning pcv valve will make excess crankcase pressure and blow oil everywhere. Check there. You might have worn piston rings that are causing blow by also
