Hey, I have just bought an 2004 Honda crf450r, and it has water in the oil, as well as oil in the coolant. So my question is, is it the head gasket or the water pump? Or maybe something else? Is the crf450r a good bike, or should I just fix it and sell it again? I haven't been riding in maybe 8-10 years, so got a lot of catching up to do.
