Remove your air filter. Choke open (not applied). Hold throttle wide open. Give a quick shot of starting fluid into the hole where the air filter was. Try to start the engine. If the engine tries to start, let the throttle close. Do this a few times until it seems that the bike wants to stay running longer. I'm telling you to do this because we wanna keep things simple at first and I think your carbs are just empty and and need to fill with fuel. After the engine has hit and run on the starting fluid a few times, then pull your choke closed and try to start it on the tank fuel.
