what you want to check is the small vacum line coming from the back of your cylinder its a trans vent if there is vacum there your crank seal is out had a problem like this last time honda reworked my 450er hope this helped

Same thing happend to a mate. But it turns out he was not draining all the oil and he didn't realse there are 2 drain plugs on a 450r. But he was refilling both oil fillers and needless to say one was chucking oil out like you wouldn't belive.
