Has anyone noticed a wet spot underneath the breather/overflow hoses after their bike sits in the hot sun for the day? I wonder how much fuel can be lost this way?

Are you sure its fuel? I believe the battery overflow hose routes the same way.

If it is fuel, I can't imagine it being all that much. Perhaps if the tank was overfilled you might see quite a bit.

The battery on this bike is a sealed battery if I'm not mistaken, thus no hose.
I believe the 3 hoses down there are the Tank overflow, Tank Breather, and coolant breather.

As for the wet spot ..... it could have been gas. If your tank was full to the max the gas could have expanded in the tank.

Yes, its definitely fuel, and yes, the three hoses are indeed fuel breather, fuel overflow and coolant overflow. The battery is sealed and the crankcase breather hose doesn't terminate there.

Down here in sunny NC, its hot - really hot, and it doesn't matter what level the fuel seems to be in the tank. At work days end, I usually see what must be the remnants of at least several drops, maybe a wet spot the size of a silver dollar.

When my bike was new, it splooged a bit every few days. One night, it splogged a good amount of green gunk which I assumed to have been coolant... but after a while, it stopped ejaculating all over my driveway.

The Crankcase breather hose is actually under the tank, it connects to the airbox. If you have the service manual look on page 3-35 for the location of that hose.

I get that too, once in a while. Surprisingly enough, I've only seen it happen at work on really hot days.

Mine does the same from time to time. Its just marking its territory.

Seriously, mine does it when the fuel tank is full, or close to full, and it sits in the sun.

The crankcase is vented back into the airbox. More earth-friendly that way. :rolleyes
