How often do you need to change a Yamaha 4-stroke dirt bike's oil? I thought I heard either every 2nd or 4th ride or is it like a car, and can got a while? The reason I ask, is becuz a guy friend of mine blow his up, and had to get all new sleaves and pistons and all that good stuff, and the reason was, the oil was bad or something, he didnt change it often enough....Serious answers, and please dont be afraid to explain engines stuff, just cuz I'm a girl, doesnt mean I dont know anything about engines....Thanks in advance!!!!!!!!!
