I'm not being constructive, but I think it's funny that you can't say petcock as two words. Pet ****.
Anyways, maybe you could disconnect the fuel line and let it drain? I'm not sure if that would work or not.
Or you could tape the throttle open the whole way and then start the bike in neutral. Leave the garage open and hit the couch!
Don't listen to me.
Most fuel injected bikes don't have that. They have a fuel pump mounted in the tank, and a direct line from there to the injection. Pulling the fuel line only empties the line, the tank won't empty without the pump running.does it not have a pet ****?
if it does just take the hose off the pet **** and run a different hose down into a gas g\can and turn the petcock on..... it will take some time but it will drain..
also make sure your gas cap is off. makes it flow better
