Well Basicly my compression plug from the head popped out and I did catch it right away but could not find it. Now I killed the quad right away and went to a local yamaha dealer and the did have 1. I put it back in but the machine seems to be getting alot hotter and I can also smell coolant being burned. We hosed off all the oil on it that spit out but it seems something else is wrong.
The quad is bone stock down to the filter with appox 30 hours on it its a 04 YFZ 450
It still has power and runs good but the motor seems to be slightly louder then it used to me
Anyone have any ideas why it may be getting alot hotter then normal and why it smells like its burning coolant but you cant see where its coming from it just seems like its coming from the head/header
Sorry for the crappy details but its all I have for now. I hope I didnt hurt the motor and thats why the plug popped out
Thanks guys
