Tim,

Okay on the clearing the flooded engine drill. Next you need to check if the bowls are actually filling with fuel.

Once you emptied the bowls, you got rid of all the fuel in the carbs. To flow fuel through the gas petcock, it must be "on" and there must be vacuum applied to the back of the petcock supplied by a smaller black hose. I've seen where after the bowls were dry, people couldn't start their bikes because of not enough vacuum at the vacuum hose during starting, which comes from the carbs.

To insure you are getting fuel to the carbs, take the small hose on the back of the petcock off, stick a smaller house on there and gently suck on the hose to create a vacuum to the petcock. This will allow fuel to flow from the tank to the carbs. The best way to insure this is working is to remove the fuel line where it enters the carbs and see if gas pours out of the gas line when you suck on the vacuum hose.

Once you confirm that gas is indeed flowing, put the gas line back on the carb and as you are providing vacuum to the gas petcock, try and start the bike. You will need to plug the vacuum hose you originally took off the fuel petcock, otherwise the bike may not start or idle very rough with it left unplugged.
