no,dont take them off.use a flat bladed screwdriver.on the left hand side,right at the bottom you will see one screw for each carb.undo these screws and hopefully,all the old fuel will drain out.Thanks for your replies! I am going to try what you said.
I have a 1980 CX500. I do not know much about motorcycles, and I am learning every day. In order to drain the carbs, do they have to be removed? I have a service manual that I will look to for some additional help.
