2005 R1 water temp

I have no experience with Yamahas other than with this bike, which I now have 4 days on it.

Anyone with either an older gen,or even the newer bikes - what is your normal running water temp? My CBRs that I've owned since 1998, all of them have been 175-220 normal water temp - with moving always near 180. Granted, this is highway or street riding, not track riding, but my 600, 954, and both 1000s have always been the same numbers.

Does anyone know what water temps they have been getting on these things during a track event?

Ooof.

I was watching my videos from Summit on Monday, and I was 175 at pit out. 180-190's for the first two laps. Then lap 3, she clicked over 200, and then goes from 210-221 until I park it.

I am running straight water myself. I've noticed she makes a light (Not obnoxious, but I'm aware of it) popping on decel sometimes when over 200. I assume the bike is running lean - which would give me the popping and the high water temps.

Plenty to look at. Lean. Air in coolant system. My bikes run anywhere 180-220 depending on what they're doing.

It does have an aftermarket exhaust, and to my knowledge has an unmodified ECU. That would bring it lean most likely as well.

I mean, it is hauling around my fat butt, but Im a little surprised to see that sort of temp!

I don't think so. To be honest I did not look that deep into the engine at all. I bought the bike in April and our first track day was in May so I really didn't do much to the bike yet. The guy I bought it from, it was his third backup bike, so it was not used very much and mostly stock.
I would assume it does not have the block offs. I did just add a power commander and updated the map which definitely did change the fuel curves.
The decel popping is only once the water temp gets above about 205.

I didn't read much above so I'll just spout off. My 2018 r1 is around 180 when circulating on hot days. Add some water wetter or equivalent in increases the surface tension of the water and allows it to transfer more heat. If the bike has an exhaust and intake and isn't tuned it is most likely running lean making more heat due to the lean mixture.

Running lean has been my thought as well which is why I did the Power Commander. Yeah I was seeing water temps up in the 210s to 221 as a high last time at Summit (August)
