I just bought a new bike and its just pissing oil. I want to get a better look and remove the tank. The service manual says turn the fuel cock to on before removing everything. It also says to start the engine and get it warm and doesn't say to turn the engine off. I'm worried about leaking fuel everywhere. Is it simply removing the fuel pipe, vacuum pipe and breather pipe then taking the bolt out and popping the tank off? Do I really leave the fuel cock to ON and disconnect stuff?
