I was wandering if anyone runs a bit of Isoheet in the fuel to keep the moisture out...especially when getting gas at all these different places while riding. I see they make a few types and this seems like the one to use if you are going to. Any thoughts?

It works, I've used it for keeping water out of the fuel system and always keep a bottle with me. Really helps out when the carbs get frozen too, remove the airbox and splash some isoheat down the throat. ONLY use ISOHEAT (with isoproply alcohol) in 2 storkes, I've heard using HEET may cause damage to these engines.

The regular HEET is methanol, and is not good for the rubber and rubberized gaskets. The way these chemicals work is relatively simple: they can bind to the water, and also can mix with the gasoline.
Gasoline is a hydrocarbon (carbon atoms bonded together, surrounded with hydrogen atoms bonded to the carbon atoms). Because of electrostatic interactions, water H-O-H cannot mix with gasoline. But the methanol H3C-OH and isopropyl alcohol H3C-CHCH3-CH2OH have enough H's to deter the strong negative charge on the oxygen and can mix. Because of the alcohol group -OH, they can hydrogen bond to the water and carry the water into solution.
Hopefully that is clear?

I use it too. Its cheap insurance against siezing an engine due to water in the fuel.

Nice reply Kusko...couple too many H's for me but I got the point. I was pretty sure people used it and I just wanted to check. Thanks.
