OK I'll drain the gas.
Check the air filter.
Check the tank is venting properly.
What's the quickest way to drain the gas?
check the connector on the top of the tank... a couple pins go to the fuel sender and a couple go to the pump. since it will only kick on the pump for a second or two if the bike isnt running, you'll need to find those pins and hook up your own power source. run a rubber hose from the outlet to a gas jug and apply power. it will pump out the fuel fairly quickly.
