The early models had this happen now and then. My 00 did it once in a while, but never consistently. Later models had a baffle built in, to keep the oil from splashing into the breather.

Still, if it is happening consistently, you may have bad rings and are passing compression into the crankcase....then blowing it out the breather. Check the compression and do a leakdown test.
