I just ´inherited´ a ´72 CB 500 as a graduation present. It has been standing out of action for two years and the engine wont turn. The battery is low but still activates the neutral and oil lights. If I put it on the charger it still doesn´t do much. I checked the fuel line and there is fuel going through to the carbs, It might be flooded bc the overage pipes leak fuel. How do I get it to go? I´m not experienced with older bikes at all and I have made this motorcycle my project for the summer. Also, where do I get new tires, fuel filters and spark plugs?
