chain lube from the front sprocket cover? you've checked the oil level?
well i took my bike around to my friends house after i lost my fight with tears and gained a lovely black middle finger (cant wait to show it my bosses) he found that i have WAAAAAAAAAAAAAAY too much oil in and ended up draining nearly a litre out.... his thinking is that possibly i had too much in causing too much pressure and forcing the hot runny golden stuff out..... im keeping my eye on it for now....i'll let you all know... got a feeling i will have to replace that crank seal thou.... will hgave to be a job for after next week when i get paid....
