No, there are many different kinds of gas caps and you need to know what kind you have in order to replace it. Older model motorcycles have bayonet / cam-style gas caps (sometimes referred to as ¼ turn gas caps) that engage using a notch and a twist. Other gas caps are threaded and they screw into the tank. Not all manufacturers use the same threads so you need to find a gas cap that is made for your particular bike. It’s also important to note that some gas caps have vents that help eliminate vapor lock which can stop fuel from flowing properly.
