How do you switch to reserve tank reserve fuel switch on a 2002 Honda shadow?

To switch to the reserve fuel tank on a 2002 Honda Shadow, locate the fuel petcock, which is typically found near the fuel tank. Turn the petcock lever from the "ON" position to the "RES" (reserve) position. This allows fuel to flow from the reserve tank, which provides a backup supply when the main tank runs low. Always remember to switch back to the "ON" position once you've refueled.
