I recently mounted a digital water temperature gauge on my '07 650R which comes stock with an idiot light only. Judging by my '07 and a number of other watercooled bikes I've owned, 104C at a light is normal and since your fan knocks the temperature back quickly you've nothing to worry about. If/when temps hit 110C or more you'd better check the coolant level and overflow tank to make sure you're not low. If you don't like the difference between running temp and the dramatic rise at a stop you could add a handlebar switch to proactively activate the fan.
Running hot or not
2021 650 Ninja
So when I am on the highway it runs @ 88C at 120 km then run thorough town @ 30 - 50 k for about 3 km .
When I stop the bike in my driveway the temperature climbs to 104C in about 30 to 45 seconds then the fan comes on dropping it down to 98c, this is on a day when its only 16 degrees out.
Then when you shut it off sounds like the exhaust system is pinging from being hot.
I have changed the coolant & thermostat
Is this normal ? or are we running hot?
