Default High cruising temp, overheating and fan problem

I need the help of the forum members to diagnose this problem i have with my 02 f4i. Cruising on the freeway, the temperature will be around 210. Sitting in traffic is dangerous as the temp will reach to over 254 and the dash lights start blinking. The fan doesnt kick on at 220-225. It turns on at 240 and turns off when the temp gets back to 240. I've already flushed the coolant and using engine ice right now.

You already figured out the problem. Make the fan turn on at 220 again. The cruising at 210 doesn't really tell us alot. My bike cruises hot as well when its 115* outside here in phoenix, situation the same for you? Otherwise check the flow of coolant and check the thermostat.

Sorry about that. On the freeway, my bike is at 220 when it would normally be at 178 degrees. This is on a 70 degree or cooler day. I can't take the bike out when the air is warmer or else the temps will stay high. what are ways to check the flow of coolant? I think I need to start there.

Sounds like a potential thermostat sticking. That would be my first thing I did was swap the thermostat right fast and giver her a whirl. With temps that high it may be getting stuck closed, hence the lack of flow causing unusually higher temps. Besides its a quick and cheap fix, if you do it yourself.

Yeah man, After the swap take it for a quick ride and let me know how it did. If it still rides hot I would see if you have flow to the tank. You can let it warm up then pop the top off the tank and look for liquid within the tank trickling like its flowing. If not you got a bad pump, however 9x out of 10 its the t stat.

Thermostat not opening properly sounds to be the cause. They are relatively cheap and fairly easy to replace. Be sure to give us an update.

Hey guys. You wont be too happy with this update, but i haven't swapped the thermostat yet.

I finally got one and I'm ready to tackle the job. Do i need to drain the coolant to do this? I'll be putting my bike on a rear stand so it will be level while im working on it.
