So I just bought this 06 600rr. It's been great until this morning. When at idle or below 35mph, it starts heating up. This afternoon it got to 270 degrees while on the freeway because i was only going 25mph. I had to pull over and shut it off and let it cool. Once I get above 40mph, it will ride perfect between 180-185 degrees. The lady I got the bike from has the maintenance records. A complete tune-up and valve adjustment and everything was done 10k miles ago. This is my first bike, so this is all new to me. Where should I start looking?
