Anyone know anything about engines? I really need some help. I thought my li'l dearly beloved motorcycle was fixed when I had the oil system overhauled but it's dropping it all over the place now, and the oil it does still have in it looks like vanilla yoghurt, which ain't good. I keep topping it up with good stuff but it's not helping matters. It's an air-cooled engine so I can't check to see if the coolant's going down (cos there ain't any!) but it's looking like the head gasket's gone to me. I'm FAR from an expert on this so anyone with any knowledge please reply or PM me I've gotta get it stopped one way or another cos the oil's starting to hit the back tyre and that's a potential disaster waiting to happen, for obvious reasons!
