2003 sportster wont start after it gets hot..fine if it sits for about an hour, has plenty of spark when it has a no start and smells of fuel

Sounds like the fuel in the float bowl is percolating. This means the fuel in the float bowl heats up and boils when you shut the engine down. Don't worry, it won't explode or anything. I've seen this quite often even on carburetor equipped automobiles. In a car, it's called a "vapor lock". The trick is to get the engine to run cooler. You engine is jetted very lean so that it meets EPA emission standards. Because it's fuel air mixture is so lean, it's running hot. Take the bike to a performance oriented shop and have them richen the carb up to the next richer slow speed jet and readjust the idle mixture screw. They may want to put a 0.020: shim under the needle to richen up the mid-range mixture a bit as well.

Good Luck
