Hey guys, I recently picked up a really nice 06 yz450f and am in need of doing an oil/filter change. I forgot to get the manual from the guy i bought it from but I called and he is mailing it out. I just need to know like step by step directions for draing the oil. I came off a 02 yz250f so i know how to do the filter and such, but just dont know where to drain the oil from or how much to put back in(Ive heard 1qt???). Thanks in advance for the help.
