Coolant boiling out?

Agreed. I guess I'm feeling extra anal retentive tonight. God I'm bored.

Obviously the fan would cool down the coolant in the radiator, but with the engine off I would assume coolant would stop flowing and therefore the fan is only cooling down the radiator versus the engine. Or would the minimal air being blown on the motor combined with the cooling radiator make a difference?

So it was just run off from the bottle overflow. I guess running the fan with the engine off might help but it's not the best for your battery. Next time you service the bike you could try "EngineIce" .....it runs alot cooler .

I was just thinking about ordering some. If the bike is pulling this crap now, I don't want to know what it will do when it gets Georgia HOT with 100% humidity.

Can I order it as a straight up mix?

Yes....no need to mix with anything. It's ready to go as is.

Excellent! I am about to 4k miles, and I hope to give my bike a good full service to get familiar with it before riding season really gets under way.

My SV the fan will not run after the key is turned off
On the 1125, it will... for a long time.
The fans also come early and often. haven't seen over 180 on it yet.

Put a bit of water in the resevoir today and let it idle through a couple fan cycles, no issues. Hopefully the sun with be out tomorrow and I can put some traffic wear on it.

Should order my engine ice so the non distilled water wont be in there long.

A trend that started with the Sporty-based engines. Overheating rear cylinder jones.

Glad you hopefully have it figured out.

The only time this happend to me was with a 93 ZX-11 that I had just had an aftermarket exhaust (full system) and a jet kit installed. Trailered it to Daytona for bikeweek...rolled it off the trailer...rode into town...got caught in traffic...hot as all get out in Daytona and yep...coolent started bubbling out.

What my issue turned out to be is that my aftermarket header was bigger and was too close to my "plastic" fan and yep...the fan blades melted.

The rest of the weekend was ok as long as I kept moving and kept the air circulating...no more downtown riding.

Got home...swithed to an aluminum fan and no more issues.

Live and learn.

Another tip: when using water to top off or mix coolant, always try to use distilled water. Calcium and other minerals in regular tap water will come out at high temperatures over time, and coat the inside of the radiator, thus lowering the cooling effectiveness of the system. The same thing happens to water heaters in homes. Granted, the problem will only happen over a long period of time, but it does happen.
