I inherited a 2001 soft tail from my deceased brother. It´s a beautiful bike and I´d love to be riding it. Do to the unfortunate circumstances I really didn´t get any input on how to operate it. I know how to ride a motorcycle so that´s not a big deal. Could someone please explain the best way to run the throttle? Also, which way should the fuel petcock be to allow the fuel to go? Horizontal or vertically? I know one is to stop fuel the other allows fuel to fruit freely. Any help is appreciated thank you.
