so a buddy of mine's brother just bought an EX in great shape, but it spits a good amount of oil out of the crankcase breather. the person who owned it before removed the plastic catch container and installed a mini filter breather (knowing it was spitting oil), and after actually getting to ride it for awhile today it really is putting out oil.

what could this be? he is going to check to see if the oil level is too high, but what other possibilities are there?

providing your oil level is correct,
it is probably caused by blow-by.

do a compression check and see if it up to par.
