I have the same thing. Used Mobile One twice. Then, switched to Yamaha last change. Gas is getting in my oil now. Overheat alarm sounded twice last time out. Dip stick shows more "oil" than I put in and checked meticulously several times. Overheat alarm happened at higher RPMs then goes away. Heard anything?"

It is at dealer now been there two weeks but i don't think they have looked at it yet. I have seen a few post of people saying that they had same problem with this engine--but have not been able to get an answer yet. I don't think the oil was the culprit but an internal problem yamaha may be having -I will let you know
