All i gathered was a big chunk when i drained the oil so i figured how the hell can a big chunk get through the oil drain hole. Then he's saying he drained the oil out the crankcase cause he oiled the pistons up before (holy shit balls that's alot of oil). Here's my advice bring it to your local yamaha dealer and tell them to fix it in those three words cause if your speech is anything like your typing skills there gonna call the mental institute and ask if a patient escaped.
