I have a 04 400ex. Can anybody tell me if u have to put oil in 2 seprate spots. I know it has the bolt on the side of the lower crankcase but im not sure if u have to put oil in that or if u can put it in the oil cooler spot and it will get to the crank case. I really need help on this so if anybody can help that would be great. I also just broke that bolt on the side of the crank case that u check the oil at. Very dumb of me. Does it have to have a heli coil. And is this gunno be a spendy repair. Any help is apreciated. thanks.
