i was told the head gasket was bad. the local yamaha dealer has been getting complaints with blown head gaskets.

 

that' a new one on me. sounds like a dealer's tryin to make a little money....

 

I guess my shee overheated cuz it was making that "percolating noise" I just let it sit, sprayed out the radiator with a hose.. put some anti freeze in it, and let it sit fer bout an hour, and it worked great after that. I was just riding down the road when it happened.. I thought I had hit a bump with some water in it.. and I looked at my expansion chamber, and it was covered with green stuff.. I said oh **** and haulled azz home. It was the first time it has ever over heated, and I didn't know what was going on.. sorda scared me. haha. Well, later,

 

This site has information on relocating the coolant reservoir:

May or may not apply to you.

From the site...

With the factory tank location and breather tube routing, it doesn't take much down slope to put the reservoir above the "high point" in the tube causing a situation where the coolant can gravity feed right out of the tank. On top of this problem, the low spot in the tube acts as a trap and fills with coolant that sloshes into the line. When the radiator vents pressure, this trapped coolant is pushed out.
