Crossfire 800 diamond drive leaking

I've got a 2010 cfr 800 with 4800 miles, On my last ride last year I noticed my diamond drive spewed oil all over its cover and everything around it, since I was riding it hard that day boon docking/ tailwalking and things like that to the point it actually blew the top end I figured maybe it just pressured up and all came out through the vent in the threads or somthing( I've seen small amounts come out of here lots but never a large amounts) so this summer I rebuilt my top end an decided to just clean all the oil off of everything and refill my diamond drive to see if any leaked out while it sat for the rest of the summer rather than splitting the case witch I just did last fall to do the 6203 bearing upgrade and replace all other bearing and seals to freshen everything up, witch held up for 800 miles last year until the point on my last ride were 6oz of the 15oz leaked out, so seeing no oil from sitting all summer I stuck to my original thoughts of how it leaked out and began breaking in my new top end going back and forth in the feild today, nothin crazy, after about 20 miles I stoped to check everything out and sure enough there's a fresh coat of gear oil all over the dd and surrounding area. I'm having a hard time telling were its coming from cause it just seems to fling off my driven clutch and not stick to it. Any ideas?
