In the era of 10% ethanolic fuel, the answer is simple:  your pilot jets 
have gummed over.  You can try a double dose (2oz/gallon) of seafoam first, 
but the most foolproof way to fix is to remove the carbs and physically 
clean the pilot jets.

Good luck.  Not a difficult problem to solve, but it does involve removing 
the carbs.  In my experience the hardest part of the entire job is getting 
the upstream boots (from the airbox) back onto all four carb throats.  A set 
of dental picks helps a lot.  So does patience and beer.

Word(s) to the wise (and anyone else who will listen); use a fuel stabilizer 
on every fillup all year round and store with your fuel tank full when not 
riding, even is season.  This will cut down on your fuel related carb 
problems by 90% or more.  Use a 1/2 label dose of stabilizer in season and a 
full dose out of season for every tankfull.
