Default Overheat Prevention

So I know F4i's are known to run hot when riding slow or at stoplights or in stop and go traffic and I've got a secondary fan on a switch to use for these occasions. Unfortunately, its not quite enough. Is there anything else cheap I could do to keep the temp down?

Define "not enough" as my bike is stock and AZ gets to 115* for months on end and I have no problems.

while riding, im fine. bike runs between 190 and 210. but when i start slowing down/stopping, it gets up to around 230, and often 240. Once it hits 250, i pull over and shut down.

Um that's not normal...something is wrong with your cooling system...I too live in AZ and its 115 degrees out and even at this temp I cruise at 172-185 and stopped its at 200-225......The fan on my 01 goes on at 220 and I've NEVER seen it above 225...even after sitting at a light for 15 minutes in 115 degree dry heat.

If your bike keeps rising above 225 and you dont hear the fan then somethings wrong...

You didn't say whether the fan comes on automatically at around 220F or just with the switch you installed. Also, have you ever changed the coolant? If so, could there be air in the system?

Some owners say they have good results with Engine Ice. I've never used it but there seems to be lots of info if you do a Google search for something like motorcycle engine ice.

I replaced the fuse to get the fan going a while back, but havent thought to check against the secondary fan. I also did a coolant flush about 2 months ago and made sure there were no air pockets. I may have used the wrong coolant. i'll check the fan and try to pick up some engine ice and re-flush it.

If the previous owner of your bike didn't keep up on the servicing then the radiator might be slightly plugged. Also make sure the fins in the radiator aren't all bent. Engine ice isen't needed if the system is running properly.

Coolant change for sure. Engine ice is very nice stuff.
