Hello all! I know operating temps have been gone over and over here, and there’s a huge variance in them. At any rate, I need some help/advice. My brother bought an 07 ZX6R yesterday, and while riding home he overheated. Temp hit 241F. Shut it down and let it cool and topped off the coolant. Didn’t observe any leaks at the time. That was within 20 minutes of purchase. Rolled on and made it another 40 min before overheating again. This time was in traffic. Got it shut off around 230F. Temp light was flashing. Fan was running. He called me and I came and got him and the bike with my truck. He used less than half a quart of coolant, but there was a definite puddle under the bike when I got there. I’m thinking thermostat, but I need some ideas. Is there damage to engine Likely at those temps? Could the radiator have a hole/crack? I saw wet on the exhaust headers, and the inside of both fairings. It looks like it could’ve come from radiator, hit the fan and slung everywhere. I’ll be striping the bike this evening to get a better idea of leak. Just curious if anyone has any ideas why it would overheat while still having coolant in the bike. Sorry for the book. Just trying to be descriptive. Thanks y’all! FYI in North Texas and temps outside were mid 80’s yesterday.
