Hello,
I'm a total beginner to bike repair. Does anyone know or have a video that shows how to replace my old petcock with a new one (which I have purchased)? I'm clueless how to drain the gas, remove the tank (if I need to), and install the new gizmo, but I want to use this as my first foray into leaning how to work on my bike rather than trying to find someone nearby who I need to pay an arm and leg to. Anything that really breaks it down and assumes no prior knowledge would be incredibly helpful.
Much obliged,
