You need to remember that on a hot day, the fuel you put in the tank is also at an elevated temperature, so riding immediately really isn't an issue.
This is incorrect. The fuel you put in your bike is much, much cooler than summer ambient temperatures as it is stored underground. Actually, a fresh new tank of gas between the legs is a welcomed feeling on a blistering hot day!
I don't know what the thermal expansion numbers are on gasoline, but it wouldn't be too hard to get and calculate. My guess is that we're not talking about a lot.
