It was the thermostat causing issues with my bike, It would overheat in traffic and spew coolant out the overflow on hot days. But if your bike is staying within normal range and your fan is working then it's all good.

 

@RedBaron so how did you end up fixing it? because if there's a bumper to bumper situation my bike gets near the H it has yet to reach the actual H but I don't want to wait for that to happen

 

I've owned several different model sportbikes from yamaha, suzuki, honda, and
one kawi zx-7r...every one of them rocketed
toward the H at idle in traffic, perfectly normal...as long as the fan is working. It's been many years since the F2 was my trusty steed so hopefully someone else can chime in. IIRC there are two coolant drain screws pretty much directly above the headers and one on the water pump thats on the left side of the bike as you sit on her. You'll see the return line from the left side of the radiator leading to it. Unscrew those 3 bolts (either 8 or 10 mm) and let the coolant drain out. Be sure to remove the radiator cap while doing this. Once drained torque those bolts back down (i'm not sure of the specs for them but it isn't much). Now you refill at the radiator cap opening with your prefered anti-freeze. DO NOT use dexcool or any variation of that crap. Pure ethelyne glycol like Peaks with distilled water or one of the 50/50 mixes like Prestone is fine. I personally use Engine Ice..great stuff, I highly recomend it but at $20 a gallon it's not for everyone. Anyways, top off the radiator and fill the overflow tank to near the max line. Almost done..to be sure you've removed any air pockets in the cooling system you need to fire her up and let her idle until shes good and hot. While shes idling when she gets up near the H the fan should kick on and confirm it's doing its thing. Easy to check that, you just listen for it, can't miss it. If that checks out shut her down and enjoy your cold beverage of choice. Let her cool down for at least an hour and repeat the heat up/cool down two more times. When shes cool and before you fire her up check the coolant level in the overflow to be sure it stays near the max mark. After 3 runs you should be good to go with no air pockets in the system. Shes locked, cocked, and ready to rock! Like it was said before we all started not knowing
much and this really is as easy as an oil change. You can be proud you did it yourself and save a load of $$ on labor
costs for that nice shiny new piece of hardware for her. Hope this helped and good luck!

 

Good write up fob^^

@USMC_Arango basically I just did a coolant flush like Fobwareagle explained, and put in a new genuine thermostat. The new cap I bought wasn't sealing properly so I tossed it and put the old one back on, and it all seems fine now as temps stay between normal on the gauge, and doesn't overflow coolant.

But they do get pretty hot in traffic which is ok, as long as the fan kicks on and it stays out of the red.
