09 1125cr. Had this bike since new on 09 just shy 20k miles on it.

Was out riding yesterday and after a hard fast section if curves I looked down and the "cold" warning was on in the cluster...? I tried to scroll to the batt/temp display to look at the coolant temp but being that the cold warning was on it only gives you the gear option or the bright option to look at. After a while it went off and I was able to display the temp and it was in the 150's. It kept switching the cold warning off/on for the ride home. I haven't looked into it yet but I wanted to check in here to see if anyone had seen anything like this on the 1125? It was not cold out. Probably 70ish degrees and after an hour of riding.

Check the temp sensor.

Thermostat could be stuck wide open - often the classic cause of running cold.

No need for a thermostat when you live around Pheonix. Same thing here in South Louisiana.

the thermostat is there for a reason. it helps the bike warm up faster even when its warm out, and maintains engine temp at the proper temp. like they said above, id start with the sensor and then check the thermostat itself in a pot of water on the stove.

You don't need to pull the stat to test it. In order to pull the thermostat, you'll basically have to drop the motor to get to the hose clamps holding it in place.

Easier way: Flow through radiator should be near nil at start up when system is cold. Just pull radiator cap and look in - If you see flow when engine is cold, then thermostat is open.

Normally, as the engine water jacket gets up to heat, the stat will open and direct flow to the radiator. Monitor CT and see when flow starts.

Just an update:

I rode the bike a few times and it acted totally normal, the it started acting up again giving me the cold message periodically while riding and fully warmed up. I would switch to the temp display and watch it and it would fluctuate from 185 to below 150 where the cold message would come on. Then very rarely it would jump to 229 or 227. Started looking for a connection issue at the temp sensor but it all looked good.

Put a temp sensor in it and it's all good now.

Sensor is located in the front jug below the throttle body and injector housing, you have to access it from the top. Bosch sensor part# 0280130093
Was in stock at the local NAPA.

Did you have to rotate the engine or pull the frame to get to it, or was pulling the air box and throttle bodies sufficient to gain access?

Once the throttle bodies are off you can get to it.
