Alright, So I just bought a '93 blaster and I don't really know anything about it. Yup, Im a noob. There's a few things I think I need help with. First off, it leaks oil.. I think it might be the gaskets. I also wanted to know, what kind of oil I should put in the crank case. Can I Use 4stroke oil.. Cause I've got lots left over from my last quad.
