Just bought a YZ426, new from dealership. I'm breaking her in with caution and babying her for the first tank, half throttle and all. The problems comes in when the bike had only two hours on it. I had checked the oil level the next day and the dealership had put too much oil in upon prep stage. Alright now I'm thinking about gaskets blowing or something else. There was oil oozeing down from the head gasket area. I brought it back the next day and they wouldn't let me back in the service area, so I can't say what exactly they did. (by the way I know about the dry sump oil level checking process) Anyway they had kept them for 4-5hrs. in their shop. When I picked them up they said all they had to do was "drain the oil and refill". When I ask about the gaskets they said they were not harmed. I do not consider my self a mechanic but understand basics of engines. *** THIS IS WHERE IT GETS INTERESTING*** I askes where the oil is coming from and thay said there is an over flow hose coming out of the valve cover. Then when I get it home I took it around the block a few times then parked in the garage, only to find a white foam dripping from the over flow hose they were refering too. I have ridden it two more times and happens everytime but only oozes after it sits. I know that the foam comes from gas or water mizing with the engine oil. The dip stick looks normal like honey but why is this happening??? Please advise fellow thumpers, I'm pretty new to this seen. Is there something I should look for or be carefull of? Any information is greatly appreciated!!!
